The Nix and Zapruder Films: 1. What is the difference between Nix and Zapruder films? The Nix film was filmed by Orville Nix, just on the opposite side of Elm St. from where Abraham Zapruder filmed his. More precisely, he was located at the corner of Main and Houston Streets. Both films show various details of the fatal head shot though, to be sure, the Z-film (as the Zapruder film has been called) has been the more extensively studied, and is perhaps the most analyzed film in history (5, ibid.) A frame from the Nix film(+) may be seen in 7, p32. Best of all, try to view the entire intact video. The best version I have seen (intact) is in the Italian made (1976) video 'The Two Kennedys'. One can clearly see a smoke puff rising from behind the fence of the Grassy Knoll - just as described by a number of witnesses standing on the Elm St. Overpass including: Richard Todd, and S.M. Holland (see, cf. the video 'Rush to Judgment' and segments of interviews with Holland, Todd, Lee Bowers and others therein. In the intact Nix film, clearly visible, is the fragment of skull bone, seen rocketing over the trunk of the car as a direct result of the head shot. In 'The Two Kennedys', this fragment is ringed for easy identification throughout its trajectory. There is not the least doubt in my mind that this is indeed a dislodged bone fragment, and more than likely the selfsame fragment (occipital) found by William Harper subsequently, about 25-35' behind where the limo was when the shot was fired.(Also noted by Mr. Charles Brehm - who was standing only 30' from the limo at the time, but never called by the Warren Commission). A missing occipital bone would also comport with the hole in the head as described, for example, by Charles Crenshaw at Parkland (10, p86).(See also details given in previous section of FAQ). From a purely physics point of view, the motion of the fragment over the trunk clearly shows the direction of momentum. Its motion is also perfectly consistent, and matched to the other kinetics visible (i.e. the head shot, direction of head motion , etc. ) This also indicates irrefutably, that the shot that produced this backward propulsion of bone had to have come from the front. (Note Jackie can also be seen in the film moving over the trunk in an attempt to snatch the flying fragment (cf. Z-film 7, p38, lower right, p192, bottom) and her own testimony appearing in transcripts (WC, Vol. V, p. 180) indicates that is exactly what she was doing. Charles Brehm in an interview ('Rush to Judgment', 1986) also notes the displacement of what he believed to be a skull 'particle' to the left and rear of the limo. Reference has been made to Martin Shackelford commenting that "it seems like a skull fragment flying through the air would be in more than one frame" (3, p76, 77) - but it is clear to this observer that what Shackelford was looking at was *not* the original - intact Nix film, but rather a doctored substitute that emerged after "the original film was lost during the HSCA investigations"(3, p78) Certainly, the version of the Nix film I have (on 'The Two Kennedys') shows more than 'one frame' and, as I indicated, it is tracked with the aid of a reference circle (estimated duration: 0.5-0.6s or 8-10 frames). It is evident to me that more than one version of the Nix film is in circulation, and that there is no assurance that anyone looking at a copy will see the intact version. ('The Two Kennedys' is dated 1976, or two years before the HSCA investigations where "original copies were lost") Orville Nix himself (interview, 'Rush to Judgment') notes that there was an original of his film (which went to UPI) and a copy of that - which went to the federal investigators. When his film was returned to him (the gov't version) Nix pointedly noted that it was *not* the same as what he had originally given them. In fact, he observed "a frame here and there was missing". Assuming that no one knows his film better than Nix himself, this leads one to suspect that at least three versions of the Nix film are in circulation: - The original (UPI) unedited version (also in 'The Two Kennedys') - The tampered version returned to Nix (frames missing) - A 2nd tampered version - after a copy 'disappeared' during the HSCA In his book 'Killing the Truth', Harrison Livingstone notes (2, p77): "Doug Mizzer reports evidence of forgery with this film, with a frame having been removed following the headshot. His theory is that the first frame shows the vapor from the brain shot at the moment of impact on the front of the head, and the following frame shows a large piece of skull fragment in the air coming from the back of the head. This would be conclusive proof that the shot came from the front." It should also be noted that an original film by Marie Muchmore also caught the critical instant - and was film facing the Grassy Knoll. Unfortunately, her film was confiscated, and when returned the key frame had been mutilated (cf. 7, p37, middle) Certainly, and remember this is a *conspiracy viewpoint* FAQ, the cumulative tactical 'hits' on the evidence must set the nerves of the sincere truth seeker on edge. While critics carp about a mere 'set of coincidences' or 'oversights' and the 'inability of the government to do anything right or keep secrets' - it is clear that whoever is behind the pattern of evidentiary compromise has had an uncanny ability to target the most critical evidence (films, etc.) and render it near useless or absent. As these instances proliferate, the 'psy ops' theory of Livingstone (see 3A of FAQ) escalates to ever increasing prominence and credibility. Fortunately, in the case of Nix's film - not all copies have been 'adjusted'. I have seen at least one version, in the Italian made video 'The Two Kennedys' which shows the flying bone fragment with a reference circle through its whole trajectory. There is no doubt in my mind that: a) it is a genuine object - not an artifact (since Jackie is seen actually reacting to it, pursuing it, and b) there are no frames missing from the sequence. Mark Lane also notes, in regard to the Nix film, that it (11, p.57): "provides graphic evidence that she (Jackie) apparently was reaching for a portion of the President's skull that seemed to be driven over the back of the automobile. This possibility is supported by the testimony of Clinton J. Hill, a Secret Service agent, who ran from the left running board of the followup car back into the limousine. He told the Commission that it appeared to him that Mrs. Kennedy was reaching for something flying over the rear of the car." By contrast,. the version of the film shown at the beginning of Part 3 of the Nigel Turner series 'The Men Who Killed Kennedy' is decidedly different. It is shorter (estimated 1/10 sec - 1/20 sec) and the bone fragment cannot be seen other than in the very initial part of the sequence, maybe for 1/10 second. Indeed, the fragment shot is so ephemeral that one could indeed come away with the impression it is an artifact or 'light trick'. (Though if the blown up view is studied carefully and re-run, this is dispelled.) Obviously, however, the perpetrators have not been able to get all copies replaced, since - as I indicated, mine shows the whole trajectory. However, their ploy has managed to arouse ambiguity and obfuscated the identity of the real Nix film. As with every other piece of evidence that 'seems' to have made it though the covert net of concealment, the fallback defense is one of neutralization by counterpoint and spurious information. This has been the ongoing predicament faced by conspiracy theorists. The psy-ops warriors and pawns who have deliberately tainted the evidence, have kept the didactic dynamic in a state such that "anything can be believed" but "nothing can be known". 2. Was the Zapruder film tampered with? How? Yes - "the only available print of the Zapruder film at the time was extensively tampered with. Frames 155 and 156 do not exist". (1, p185). The film was spliced initially at this location, though the owner (TIME, Inc.) denied this was the case. (ibid.) Also, "the Warren Commission only began to print the film starting with frame 171".(ibid.) Eventually, the story making the rounds was that a 'junior employee' - put to work on it in the course of enlarging, 'damaged the key frames' (op. cit., p186). We will leave the percipient consumer of information to make of this what they will. Some personal (e-mail) communications (by persons preferring to remain anonymous) to me, have also disclosed that various copies of the Z-film (like the Nix film) appear to have the skull fragment airbrushed out. (Jackie is seen pursuing it over the trunk - but now it isn't there). Again, fortunately, I have a version of the Z-film which does indeed show said fragment, comporting fully with what is observed in the Nix film. (Note - in the Z-film this is in the sequence from about Z-314 - Z-353. In some Z-film versions, of course, the latter frames may have been excised - another regrettable turn of events). Also, there has been speculation, still highly controvesial, that the Z-film was altered to conflate two separate shots into one, or 'nearly' one. See 3 (2), below: 3. How do the Zapruder and Nix films disclose the underlying physics of the head shot? Each shows clearly the crucial head shot but from opposite sides of the street. In addition, the fragment of skull is seen dislodged, and flying over the trunk of the limo - *with Jackie in pursuit.* This shows that the fragment was not a figment, or 'light effect' - because an individual *in the film* was reacting to its motion! The physics can be deduced from this - based on a model in which a frontal force is exerted on the head, eliciting a displacement. In what follows I present four different approaches: Cautionary Points: (1)The different alternative presentations are provided precisely because I suspect *one* unique model cannot encompass *all* the elements. For that reason, it is rather amiss to 'home in' on one, i.e. the torque model and focus on it to the exlcusion of the complementary approaches. This is not at all strange in physics, and there are numerous precedents, for various situations. For example, both the 'liquid drop' and 'shell model' are needed to describe the atomic nucleus. They perform a complementary function - each describing particular aspects. While I am not claiming that bullet shots necessarily approach the complexity of the atomic nucleus, it is true that complementary pictures/models may still be needed - say if the evidence of the shot has been tampered with, or altered. (As appears to be the situation in the JFK head shot, as Livingston and others note) (2) At a realistic level, both the free-body (head) and the torque (torso) models give results at the extremums. (Boundary values) Thus, the torso model motion would give the lower limit (or bound) while the free body model gives the upper limit (bound). The actual result, taking into account all the sundry uncertainties, is probably somewhere in the middle of these two (extremum) limits. Again, this discloses why it would be wrong-headed to seize on one result and neglect the other. The Approaches: 1) Treatment as a pure inelastic collision (chaotic version): As Simon notes ('Mechanics', 3rd Ed., Addison-Wesley, 1971) p. 181: "Collisions of inert macroscopic bodies are always inelastic and endoergic (Q < 0), the kinetic energy being converted to frictional forces during impact. The kinetic energy of translation may also be converted to kinetic energy of rotation and conversely. Such collisions range from the nearly elastic collisions of hard steel balls - to the completely inelastic collisions in which the two bodies stick together after the collision." In the case of the fatal head shot (Z-313), this is probably somewhere near the middle of the range cited by Simon, and perhaps much closer to the inelastic side of the spectrum than the elastic. The primary difficulty is in quantifying this to a high degree of precision. If - as I and many others suspect - a 'dum-dum' bullet was used, then the only likely way to proceed would probably be along the lines of a Liouville formulation - in a multi-phase space, of particles N and dimension:N x6. By way of example, if the dum-dum exploded into 540 particles, and the head into 5 - we would need to work out a density function N of the form(Phase space dimensions 545 x 6): N[(X1, X2, ......X545)(V1, V2.......V545(t)] = [d(X1 - X1(t)d(V1-V1(t)) d(X2 - X2(t))(dV2 - V2(t)).... ....x d(X545 - X545(t)(dV545 - V545(t)] where the 'd' is really a delta - as employed in the Dirac Delta function. Because of the inelastic nature and high frictional components - the density would *not* be conserved and we would expect: dN/dt <> 0 2)Simple version of above (no jet) Clearly the complexity entailed in the above would make any straightforward solution all but impossible.I therefore use the completely inelastic model of Simon, for which the final head velocity can be computed from (p. 181): m(b) v(b) = [m(b) + M] V(h) where M is the 'head mass' ( estimate 3 kg), m(b) = 0.01 kg (bullet mass - equal to the 160 grains postulated by a number of authors including LNutter Posner), v(b) = 545 m/s (metric converted bullet velocity for Mannlicher-Carcano, 1800 f/s). Then: V(h) = [ m(b) / (m(b) + M) ] v(b) = [ 0.01/ 3. 01] 545 m/s = 1.81 m/s which comports with a number of the velocity estimates given - including by Nutters in this NG (cf. 1.8 m/s or 6 f/s by D. Hixon in 1994). Note that this is a purely dynamical result - no 'jet' needed to produce it! 3) More complex version - with jet and fragmentation reckoned in: In the more complex version, the head is treated as an initially moving free body (due to the limo's motion). Since the limo speed was at approx. 11 mph, this would be 4.9 m/s. Accordingly, as an inelastic collision, we require (The kinetic energy is not conserved): total momentum before collision + total momentum after = 0 or (using P for momentum) P(before) + P(after) = 0 The head (3kg) is moving initially at 4.9 m/s to the RIGHT (vector +)" -------------------> P (h) = 14. 7 kg m/s the bullet is directed to the LEFT (c=vector -) <---------------------------- P(b) = -6 kg m/s where a bullet speed of 600 m/s is assumed, (The muzzle velocity of the Mannlicher-Carcano is estimated at 2100 f/s or 636 m/s) and bullet mass of 0.01 kg. Thus: Total momentum before collision: = 14.7 kg m/s + (- 6kg m/s) " " " " " " " " = 8.7 kg m/s Now, since the sum of the total momenta (before and after collision) must be zero, this means that we require: Total mometum After collision = - 8.7 kg m/s In other words, it is directed toward the LEFT. Checking: P(before) + P(after) = 0 [8.7 kg m/s] + [-8.7 kg m /s] = 0 We know that 1.2 kg (approx.) of mass was lost, 1.0 kg of blood and tissue, and 0.2 kg mass of bone fragment. An estimate of the fragment's momentum can be found from the range of the bone fragment. We can calculate the range using: R = v(o)^2 sin 2(X)/ g and thence the velocity v(o): v(o) = SQRT ( R g/ sin 2X) where v(o) is the initial velocity and X is the 'launch' angle, g the acceleration of gravity (we use 10 m/s^2 to comport with the other approximations, estimates). For the range, we adopt 25 feet, or the estimated distance the Harper bone fragment landed from the limo just after the head shot. (cf. 1, p198): Thus, R = 7.6 m. then v(o) = SQRT (7.6 m * 10 m/s^2/ sin 90) where X is estimated at 45 deg. Thus, v(o) = - 8.7 m/s (since it is directed leftward) However, this does not take into account the 'launch' is from a 'moving platform' (i.e. limo) moving at 4.9 m/s. Thus, the actual fragment velocity is: -8.7 m/s - (4.9 m/s) = -13.6 m/s The momentum of the fragment is therefore: P(f) = 0.2 kg (-13.6 m/s) = -2.7 kg m/s This means that - 6.0 kg m/s is left to account for the momenta of the remnant head (M(r) = 1.8 kg) and the actual 'jet' (1.0 kg). (Note: the jet cannot be assumed to have the same speed as the fragment - since the latter is 'launched on initial *impulse*. Hence, conservation of total momentum requires consideration of head and its expelled jet during defined interval del t, but *not* ejecta dislodged under impulse *before* the commencement of del t. (cf. Young, 'Fundamentals of Mechanics and Heat, McGraw-Hill, 1964, p. 160, parag. 3 under Eqn. 7-11). To separate these two, we note that the *observed* empirical velocity of M(r) (see end of next section) is -1.6 m/s. Then, the momentum is: P(r) = M(r) x 1.6 m/s = 1.8 kg (-1.6 m/s) = -2.9 kg m/s Thus, the residual momentum, for the expelled 'jet' of tissue, blood is: -3.1 kg m/s. Note this is for a 1.0 kg mass of blood tissue expelled as jet. Thus, the jet velocity is -3.1 m/s. Considering remnant head and jet together, their tota; momentum: -6 kg m/s = 1.8 kg (v + dv) + dm(v - u) or: -6 kg m/s = 1.8 kg (v + dv) + (-3.1 kg m/s) -2.9 kg m/s = 1.8 kg (v + dv) -1.61 m/s = v + dv But we know (from empirical data, v = -1.6 m/s) so: -1.61 m/s = -1.60 m/s + dv or dv = -0.01 m/s This enables us to obtain the jet speed relative to the head (u): We assume here the jet is as shown in the Z-frames, acting from Z-312 - Z-321 or approx. 0.55s. Then the average acceleration is: del v del m [ u + del v] ----- = ------ x ------------ del t del t m or: -0.01m/s/ 0.55s = 1.0 kg/ 0.55s [u + (-0.l m/s)]/ 3.0 kg -.0.18 m/s^2 = 1.81 kg/s [u - 0.01 m/s]/ 3.0 kg -0.054 kg m/s^2 / 1.81 kg/s = u - 0.01 m/s -0.029 m/s = u - 0.01 m/s or : u = -0/029 m/s + 0.01 m/s = - 0.019 m/s i.e. the jet speed relative to the head is minuscule compared to the dynamically observed motion. What about the jet 'back reaction force on the head? F(J) = m(J) a(J) = 1.0 kg (-0.018 m/s^2) = - 0.018N So that, from Newton's 3rd law, the force on the head (acting toward the limo front) is: 0.018N And the accelerated motion of the 'remnant head' in this direction is: a(r) = m(J) a(J)/ M(r) = 0.018N/ 1.8 kg = 0.01 m/s^2 or again, minuscule in comparison with the dynamic action in the opposite direction. (The velocity on the order of millimeters per second). 4) Head shot treatment by external torque acting off -center. In this treatment I want to compare the results with those above - particularly for the head final velocity. (rev 3/98) Torque Model of the Head Shot: This is a revision of my original torque model, following certain errors having been pointed out to me by an alert Stanford physicist. The primary error was the failure to distinguish impulse action time from post-impulse (or 'coasting') time. Also, following his suggestion, I displace the pivot point to the contact point of the torso with the seat - rather than midway up the torso. I must point out that this is a *generalized* model. No claim is made to precisely replicate a *known* shot. There are a number of reasons for this: i) It is not yet unambiguously ascertained where, exactly, the frontal shot originated from. ii) There are other models based on torque possible (see, e.g. Lifton's proposal in 'Best Evidence', pp. 51-52) iii) It is possible - some would say very probable - a 2nd shot was made just before the kill shot. Livingstone ('Killing Kennedy', Carroll & Graf, 1995, p. 143) has brought up the very real possibility that two distinctly separate shots (which would have clearly betrayed a conspiracy) were ambiguated by tampering with the Z-film. This cannot be automatically ruled out - since if these (black ops technical pros) could alter autopsy film, or x-rays, they could alter any other to suit their fancy or agenda. The real tragedy in this case is that *no one* is in a position to 100%, absolutely exclude the possibility of tampering with *any* evidence presented. Since any- thing available may only be what psy-ops *want* people to see, not what actually exists in and of itself. As Livingstone notes: "..they (forgers) had a film showing *two* major and separate shots to the head almost a second apart from different directions and had to eliminate one of them. .... The fact is that a shot came from behind and drove the head violently forward, and either before or afterward another shot came from the left front and drove it violently backward. The forgers compressed the two shots into one. "The forgers eliminated most of the evidence of the first head shot except for the two and a half inch forward movement which they evidently did not notice in their haste, and compressed the action, aligning the bottom half of each frame with new and stretched frames showing the car moving along the street and grass and people going by in the background." If Livingstone's conjecture is true, and there is much ongoing dispute about this (as well as a recent book entitled 'Assassination Science' which presents an even more radical proposition, i.e. that every other frame was removed), it means that no physics model is really possible - since the situation reflected in the film is totally *unphysical*! That is - it is an artificial creation that does not comport with known physical laws. This expedient would enable psy ops to 'shoot down' anyone attempting an analysis based on physics. Nonetheless, by excluding the 'residuals' from the presumed first (forward) motion shot (which - if Livingstone is correct, are corrupted anyway) I believe some basic principles can still be shown - in terms of how a frontal shot can at least result in a backward head motion. (Again, since this is a very generalized model, I do not get into the precise comportment of the physics with the bullet entry-exit wound positions in the head). Now - to the revised torque model. (Note: the bullet velocity values used here are as suggested by Posner - e.g. see the special issue of U.S. News & World Report, Aug 30-Sept 6, 1993, p. 94). It should be understood that most conspiracy advocates regard these as far too low - and hence the resultant answers will be underestimated significantly. Despite that, I intend to show that a definite backward motion - is still feasible.) I use a torque or moment about the center of gravity, acting perpendicular to moment arm as shown below: H 0 <------ bullet (e.g. from GK)-produces force F on H ! !R ! ! x CG In the above, H denotes head, and CG is the center of gravity of the body (near point of contact with limo seat). R is the 'moment arm' (R = XO) and we assume a shot is placed at O and let R = 0.6m for ex.(The 'torso' can actually be modeled as a solid, uniform mass, cylinder 'block' centered at x and symmetrical about both sides of the axis XO. ) For ex. for a bullet of mass 0.01 kg, traveling at 545 m/s (see above) initially and decelerated to 445 m/s in 0.0004 s, we have a force of F = dp/dt = m(dv/dt) = 0.01 kg( 545 m/s - 445 m/s)/ 0.0004 s = 2500 N force exerted at O. (Comment on time interval: Assume the very reasonable estimate of 20 cm (about 8 inches) for the bullet path thru the head. At the velocities noted, this implies an average of 495 m/s for which the 'head transit' time is: dt = 0.20 m/ 495 m/s = 0.0004 s This would produce a torque (couple)T = F x R about 1500 N-m at O. Thus a shot from the front (depicted) would produce a torque of 1500 N-m that would displace the head O toward H by some angular amount. To find it we need the moment of inertia (I) of the 'torso' and from the cylindrical model we find: I = M/12[3r^2 + l^2] where M is the cylinder mass (say 50 kg), r is the cylinder radius (shoulder to center of torso dist. = 0.25 m), l =R,the cyl.length, say 0.6 m). Now, the force of the bullet F impacting at moment arm distance R from CG exerts an external torque on the torso such that: T = F x R = dL/dt = I(@) where dL/dt is the rate of change of the angular momentum of the body, I is as defined above, and @ is the angular acceleration @ = dw/dt or rate of change of angular speed). On substitution (say using the above reasonable values) we can solve for @: @ = T/I = 1500 N-m/ (2.281 kg-m^2) = 657.6 rad/s^2 This is the angular acceleration *under impulse*. From this the angular velocity (arising in same time) can be obtained as: and w = @t = 657.6 rad/s^2 (0.0004s) = 0.263 rad/s Ft _ ! ! ! !<----Impulse ! ! --! !_______________ uniform motion! !------------------------ The sort of physical situation we have can be depicted above. The foregoing treatment basically took care of the very brief (0.0004s) impulse part of the motion. There is still a uniform part left to reckon (torso motion under uniform deceleration). (N.B. The Dirac Delta function and Laplace transforms are usually used for impulse computations, but that is omitted here so as not to overly complicate the solution). Under conditions of uniform deceleration, we have: @(u) = (w(f) - w(i))/ t where t is the elapsed time over Z-frames 314-321, with a mean film advance rate of 18 frames per second. (t = 0.44s). The initial angular velocity is known from the impulse calculations (0.263 rad/s) and the final angular velocity w(f) = 0. @(u) = (0 - 0.263 rad/s)/ 0.44s = - 0.598 rad/s Again, under conditions of uniform motion we have: w^2 = w(i)^2 + 2@ (theta) whence: theta = [w^2 - w(i)^2]/ 2@ theta = [0 - 0.263^2]/ 2(-0.598 rad/s) = 0.05783 rad This must now be added to the angle made under impulse: theta (total) = theta (impulse) + theta (uniform) = 0.0001 rad + 0.05783 rad = 0.05793 rad theta (deg) = 0.05793 rad (57.3 deg/rad) = 3.3 degrees This is an extremely minute angular displacement which the entire torso makes relative to its 'pivot'. This can be translated into linear dimensions by using the fundamental definition of arc length: theta = s/ R so s = theta x (R) = 0.05793 rad (0.6m) = 0.0347 m or 3.47 cm (1.37 inches) Clearly, this is too small(see below) - but this does not mean the model is necessarily wrong. For example, the *entire* mass of the torso is taken into account, as opposed to just the head mass (as in Approach #3). This again suggests the best interpretation may be that of a lower bound on the dynamics, as opposed to a *unique* solution. The above can be compared to an independent result obtained by close examination of the key Z-film images (cf. TKOAP, p35) and a knowledge of the film timing, and geometry. Thus: The frame Z-312 establishes a good initial position for the head (lined up against the limo door on the other side - just 1/18 sec before the shot. Remember the Z-film moves at 18.3 frames/sec so this would be just into Z-313 for the beginning of the reaction time. )The other frame on the page (Z-321) shows the most rearward position. From the best estimates I've been able to make -along with some others, the distance traveled *across*- the CG of the head along the arc from Z-312->321 is ~ one foot. However, the head is moving clearly in 3-dimensions here - not only front to back but *also* to the other (left) side of limo. I estimate the leftward deflection distance at anywhere from 1.5 to 2'. Thus we have the (simplified situation where I am even ignoring the third dimension - for downward tilt of head - though I compensate somewhat by using the upper bound of R-L displacement 2'): y ! !1.5' - 2' ! ! !-----------x 1' What we want as the head displacement d is therefore the diagonal displacement d = (xy) = SQRT[2^2 + 1] = SQRT(5) (taking the upper limit of leftward distance) d = 2.24 f. The frame separation is 321 - 313 = 8 or (in time) 8/18.3 = 0.43 sec. The velocity from this works out to: v = 2.24 f/ 0.43s = 5.2 f/s = 1.6 m/s (approx.), or within the possible error of a value cited by many observers, including D. Hixon (a 'lnutter')in 1994. This (empirically) obtained value, discloses that one or more inputs were underestimated in the torque model. 3a. So, a jet effect such as some have proposed would not create this+ No - not from detailed analyses I have done, as well as reconstructions and simulations of Alvarez' methods. The magnitude of the 'jet' is simply nowhere near as large as the pure, first order dynamical effects. (See also treatment 1(b) above) 3b. But certainly, isn't it true that if the head is driven back a certain amount - say one foot, the shooter should be driven back the same amount, and maybe lose balance and fall over? The movement of JFK's (or anyone's) body/head is not exclusively the result of transfer of momentum. Complete treatment of a system requires energy in addition. Energy (KE) varies as the *square* of the velocity. Energy transferred, e.g. from bullet to body - would therefore also depend on this. The shooter's upper body is *not* required to move back a comparable distance for three reasons: 1) The force and therefore impulse produced (I =Ft) will not be as great for a recoiling rifle as for a bullet impacting a head. The Force (and impulse)depend on the *rate* the velocity changes which is more important for the bullet than for the recoiling rifle. 2) The pressure exerted by a bullet on impact with a body part (p = F/A) is greater than for a recoiling rifle - since the force F(b) in the former case is distributed over vastly less area (A) - essentially the cross-section area of the bullet. The force F(R) in the latter case is vastly diminished by being distributed over a much *larger* area (the area of the base of the rifle stock). 3) The energy (kinetic) transferred from bullet to body is much larger than the energy transferred from recoiling rifle to body - since the velocity of the bullet is so much larger than recoiling rifle (and KE varies as *square* of velocity) The above explains why the common objection that - 'a 180 lb. man shooting would be knocked backwards' is totally spurious. 3a. Is there a new version of the Zapruder film now available? Yes, it is produced by MPI Video and is entitled 'Image of an Assassination'. According to press reports (cf. The Baltimore Sun, July 16, 1998, p. 1E) "it went on sale for $16.99at video outlets." 3b How is it different from the version shown before on newsreels, documentaries? As noted in a recent Baltimore Sun article ('History Comes toYour VCR;, July 16, 1998, p. 1E, by Bob Hiassen): "Besides a lengthy behind the scenes look at the restoration, the documentary ends with a flurry of new versions of the famous sequence - including slow motion and zoom versions, where technology keeps President Kennedy front and center in each frame. Even the rectangles of blank film caused by the sprockets of Zapruder's camera have been restored to reveal, if nothing else, additional scenery." 4. Can the actual shot timing be deduced from either film? Yes - a dispassionate analysis of the film - taking into account facial reactions (using jiggle analysis), and the reactions of both JFK and Connally(7, p20-37). We must also reckon in the missing frames (155-56), otherwise the firing begins erroneously late. (1, p185-191). The results are estimated as follows (there remains some disagreement, because one or more other frames appear to have been removed from the Z-film, cf : 12, pp. 70-72). Shot 1 (miss) at Z150-52: Shows crowd reactions at missing frames (155-56), JFK too. Shot 2 (throat shot): at Z-207; JFK reacts by Z220. Shot 3 Connally shot(1st time), at 236-7, note his rotation motion, dropping of right shoulder. However, he still holds his Stetson so his wrist still not hit. Shot 4 (fatal head shot), at Z312-13 Shot 5 Connally shot(2nd time) in wrist and thigh, at Z328 (approx.) Shot 6? Tague sprayed with pavement (could be simultaneous with #5) Interestingly, this matches the results of the acoustic analyses performed by the Weiss group, which found "at least four shots that were scientifically provable, and at least two more impulses with an extremely high probability of being additional shots." (1, p224). An additional point, is that the neck shot and Connally's shot are separated by barely 29 frames, or about 1.6 seconds. This means that two rifles would have been needed. (The Mannlicher-Caracano's bolt action limited it to one shot every 2.25 secs.) The Ramsey Panel analysis (see previous section) is alleged to have 'refuted' the original study, but in fact only showed that the Weiss group had omitted some considerations. The Ramsey analysis certainly does not 'nullify' the Weiss/Barger analysis since up to now it has not been reproduced, so cannot be accepted as a bona fide scientific conclusion (I place it in roughly the same category as the 'cold fusion' claims of Pons and Fleischmann regarding some years ago - for which reproducible results were never forthcoming). Bear in mind also, that the Ramsey Panel was not comprised of actual acoustic scientists (personal communication, A. Marsh). This dilutes the value of their re-test even further. 4a But why can there be no agreement on the shot timing? You have touched on a matter with explosive political and other implications, as well as uncertainties (i.e. human reaction times). Given these factors, there is bound to be significant disagreement in interpreting when the shots occurred. Even then, these may be merely confused with the times that *reaction* took place. Interpretation is also contingent upon the filters through which one views the Zapruder and Nix films. For example, if one adopts a 'lone nut' filter, which limits the shot total to 3, then clearly there must be a massive 'compression' of shots (massive expansion of shot-to-wounds ratio) - with two or more condensed to one, and one producing 7 wounds (as the magic bullet theory requires). But - as we already saw, with the anatomical error in wound placement ('base of neck' instead of in upper back) and neutron activation analysis - that 'compressed' bullet/shot scenario is no longer viable. Hence, at the very *minimum* there must be at least four shots, and more likely five. Where exactly these occur - in the respective running of the films, is what must now be resolved.

The Rifle(s) used: 1. Could the rifle found in the Book Depository have fired the fatal head shot? This is highly doubtful. In fact, it is rather improbable that the Mannlicher-Carcano found was used at all. As Oglesby notes (11, p89): "The *magic rifle* is Oswald's 6.5mm Mannlicher-Carcano. Like its companion bullet CE399, it rates the status of magic because it too shows so little sign of having been able to do what, for the Warren Commission, it must have done. The weapon Oswald is supposed to have selected for his great moment was a bolt action Italian army rifle mass-produced in the early 1940s. It was not a serious sharpshooting weapon when it was made and two decades of aging would not have improved it." Oglesby goes on to note (ibid.) that its scope was "misaligned so badly the FBI had to readjust the mounting apparatus before it could test fire the rifle." More explicitly, in terms of the head shot, the Mannlicher-Carcano fires full-metal jacketed bullets and would not likely have left the 'lead snowstorm' seen in the radiology photos (3, p58). Forensics expert Vincent DeMaio, MD also noted that "military bullets, by virtue of their full metal jackets, tend to pass through the body intact, thus producing less extensive injuries than hunting ammunition."(ibid.) (It should also be noted that the Dallas police - in their report of the Walker shooting, which Oswald was alleged to have perpetrated, reported a 30.06 caliber bullet, not a 6.5 mm of the Mannlicher-Carcano (1, p181. Walker himself asserted the 'magic bullet' was not the same type fired at him(ibid.) More sheepdipping?) More on the 'Walker shooting': In addition, one witness - a Kirk Coleman, noted that "immediately after the shooting he saw two men in separate cars, drive from the scene."(9, vXXVI, p437) and further that "neither man resembled Oswald" (op. cit., p437-8) Even more disturbing, in the whole context of the strangely defaced photo shown Marina Oswald in the course of her testimony - in which the license plate of the car parked in front of Walker's home is effaced by a 'hole'. As she noted in her testimony (op.cit., vXI, p295): "There was no hole in the original when they showed it to me - I'm positive of it", adding (ibid.): "This is the first time I saw a black spot or have heard about a hole in the original photograph. Why does the Commission not ask me about this?" It is interesting, in light of the above, that this photographic 'perturbation' occurred precisely over the place in the photo (license plate of car) that could have allowed its unambiguous identification. Another 'error'? A mistake, or case of 'too rough handling'? The reader may judge for him or herself, while bearing in mind the fact that Oswald did *not* drive, and possessed *no* driver's license. (And logically, if he did - then it would have served the interest of the WR 'prosecutors' to have ID'd him through his plate. That would have definitely put him at the scene of the 'crime' - rather than the obfuscatory shroud left in its wake.) But - in concert, and again I reiterate that it is only *in concert* one is able to eliminate these obfuscations, the above clearly shows - at the minimum - that there is serious and reasonable doubt Oswald was involved in the Walker shooting. More than likely, as Weberman and Canfield note, in their scenario (13, p14): "A CIA agent named Lee Harvey Oswald, who had a high 'expendability rating', was chosen to play the role of 'patsy' in the killing. A covert action team was sent to the city where Oswald lived. Their mission was to create the impression that a leftist assassin was running loose by staging a phony assassination attempt on General Edwin Walker, a rightwing hero." This falls into the pattern, that the ultimate architects were in all probability extreme right wingers/fascists who fairly chuckled at the prospect of having a federal intelligence operative not only painted as a leftist 'nut', but also charged with the killing instead of them. (See also FAQ Addendum: The Fascist Connection). Nor is this the first time. The fascist French 'Secret Army Organization' tried to engineer DeGaulle's assassination in 1962. $200,000 in Permindex funds were also ploughed into this bastardized plan. Why couldn't the same Permindex plotters have turned their fascist sights on JFK? (He was, after all, regarded as a 'statist' - and in some quarters, 'communist' by the most reactionary elements of the time, including powerful financial interests who fairly drooled at the prospect of removing a major obstacle to their global hegemony. (Remember that within ten years of the JFK Assassination, the government managed 'Bretton Woods Agreement' had collapsed, enabling 'private marketeers' to take control, and drive the global economy according to their own imperatives, cf. 14, p38) Re: the rifle itself Brown (6, p26) observes: "The Mannlicher-Carcano rifle was an anachronism even by the time its weary Italian users were surrendering them en masse in the 1940s. The gun had begun its production run in 1891 and can be seen today for what it was: a product of mass warfare concepts of its time, in which huge armies charged each other, volleys were fired, and the bullets hit someone or something." The most damning indictment that the alleged weapon was used at all, derives from the 'non-tests' conducted by the HSCA's (and earlier Warren Commission's) own 'professional firearms consultants'. In regard to the former, as Fonzi observes (4, p218, 220): "but this time, the marksmen did not use a telescopic sight like the one on Oswald's rifle, but only the rifle's own iron sights. Three tests resulted in firings of 1.65, 1.75 and over 2 seconds. The target was hit on the two fastest times, but the only way the rifle could be fired fast enough was simply to point-aim it without using the sights. This was fast enough, but no one came close to hitting the target on the second shot." (And we should note here the fatal head shot was the last). And the clincher (op.cit. p220): "And while all this firing was done with the same *model* Mannlicher- Carcano, it was not the *actual weapon*, because the bolt action on his rifle tended to stick. As one of its testers for the Warren Commission reported: 'the pressure to open the bolt was so great that we tended to move the rifle off the target.' That in itself meant that the House Committee's firing tests were ludicrous." Clearly, it is of no logical or rational use to perform a 'test firing' unless that test firing employs the actual weapon purported to have been used in the actual crime. It is not good enough merely to enlist a 'similar model' which does not possess the individual 'idiosyncrasies' of the weapon used, or rather alleged to be used. This also has been the primary bugbear in all the so-called test firings. Also, regarding the actual rifle tests under the auspices of the Warren Commission, little emphasis is placed on the fact that all three Army experts conducting them were professionals in every sense, including (9, vIII, 441, 445): - 3 ranked as 'Master' by the NRA (National Rifle Association) - 2 were civilian gunners in the Small Arms Division of Development & Proof Service - 1 currently in Army, considerable background as rifleman In addition, little mention is made of the fact that the 'experts' benefited from an enhanced size of target and angular orientation, since they fired from a tower estimated at 30' height (op.cit., vIII, p444), while poor Oswald was allegedly stuck on a 6th floor window some 60' high (op. cit., vXXII, p847) In addition, no mention is made (or one scarcely recalls it in debates), that these polished riflemen fired at three *stationary* targets (op. cit., vIII, p444) while the alleged lone assassin fired at one moving at 11 mph. Thus, the test firing could hardly be called a 'replication' of the actual events. Other salient points, which put into doubt the quality of science used in this test (12, p. 149): - "The experts were timed only from the sound of the first shot to the sound of the last shot. This meant they had *unlimited* time to aim at the first target and pull the trigger before they were timed (cf. vIII, p.444) The assassin, however, had only 5.6 seconds for all three shots from the moment the car first became visible, and thus his aiming time was included in the total time." As the authors note "this is significant". If the alleged assassin required a full second of reaction time - to react to the scene, aim and pull the trigger - then he had only 4.6 seconds not 5.6, to get off three (alleged) shots. Even worse, as we saw in the previous section, they had to have made *two* shots in 1.6 seconds. An impossibility with a rifle that had a ponderous bolt action recycling time of 2.25 seconds. (Though they were not using the alleged original rifle in any case). - "When the Army experts found that the sight could not be accurately aimed at a target, they added three 'shims' to the sight to correct the inaccuracy (cf. vIII, p444). Thus, the Army experts fired with accurate sights, whereas, so far as is known, the assassin fired with inaccurate sights."(12, p. 150). They effectively converted the alleged actual rifle into an altered substitute. This is frankly not good enough. In tandem, these results cast a pall over the 'science' behind the so-called rifle tests, rendering them more a laughingstock, bordering on the farcical. Worse, when testimony was called from witnesses who knew of Oswald's firing skills (to check for consistency with whether the shots would have been 'easy' as depicted in early drafts), the most crucial witness, Nelson Delgado, was selectively excluded. Yet, Delgado had testified (12, p151) that "Oswald was a poor shot and often missed the target completely. In fact, according to Delgado, Oswald's targets were considered 'a pretty big joke, because he got a lot of 'Maggie's drawers' (complete misses)'"(volVIII, p235). Rather than relying on Delgado's testimony, the Warren Commission preferred to rely on the suspect testimony of a Maj. Anderson And Sgt. Zahm "neither of whom had any direct knowledge of Oswald's training or rifle proficiency" yet attested he was a 'good shot'.(12, op. cit., p151). Oglesby also makes reference to the simulations attempted by CBS News, in which eleven experts were used. As he observes (11, p90): "CBS does not pause to say how many total series were fired by these eleven, or how many times the two who did it once could do it again. They were impatient to state their interpretation of this result." Oglesby neglects to mention an even worse insult. That when the firing tests were conducted the branches of an obscuring tree were drawn back, to expose the Elm Street 'target'. Jim Marrs (1989 CNN interview) shows the TSBD 6th floor and the alleged shooter's window. The view from the window is clearly impeded by a thick tree branch which, as Marrs noted "was also there in 1963." Thus, we not only have an impossible weapon, but an impossible shot supposedly made from that impossible weapon - and delivering an impossible bullet (the pristine CE399). Little wonder, the new Mensa take is to flatly ridicule the lone gunman theory along the same lines as the 'virgin birth' and the Red Sox' World Series chances. From Mensa Bulletin (November, 1997), p. 11 ('Intelligence Means Having Smarts As Much as Brains') "The last time this certified genius went to the health club he left behind his left sneaker (or was it his right)? He was diligent about making his May credit card payment - but OOps, forgot to put his check in the envelope.... He also argues Oswald acted alone, believes in the Virgin Birth ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ and likes the Red Sox chances every spring... ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ "Since a small percentage of expert riflemen could do it, it was possible. Since it was possible, it was possible for Oswald. Therefore he *must* have done it." Finally, (see FAQ, Pt. 3C), the fact that a fragment of skull was hurled back over the trunk discloses that no rifle found in the Texas School Book Depository could have rendered the fatal head shot. The only physically conceivable way the dislodged fragment can be explained, is via a frontal shot. (See the Physics of how this could cause the backward head displacement, in previous section). This is corroborated by the fact that the Assassinations Committee itself "was able to conclude that there was a '95% probability' that a fourth shot was fired from the grassy knoll." (4, p260). At the very least, when all is said and done, the Mannlicher Carcano rifle could not have made all the shots -at least 5, and as many as 7, as Duffy and Ricci note (5, p100): "Even if we allow that some of these (reports) may be duplicate sightings of the same bullet - for example, perhaps the bullet that pierced the limousine's windshield was the same bullet Sheriff Decker saw hit the pavement near the center of Elm St. - we are still left with five to seven bullets that are definitely accounted for, far more than ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Oswald or any other person acting alone could have fired in the few ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ seconds in which the shooting took place." ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ To be more precise, the bolt action (as noted earlier) limited recycling to once every 2.25 secs, at the fastest. Test after test confirmed this.(9, vXXVI, p115), so that even at the minimum 5 shots (corresponding to the minimum 5 bullets inventoried from witness testimony, etc) a total time of (5 x 2.25 s) = 11.25 seconds, would have been required. This is at least a factor 2 greater than any lone gunman hypothesis would allow. Finally, the cumulative data and information, show that the alleged rifle could not have made the fatal head shot. Possibly - if whoever fired it was lucky enough, it was responsible for one of the misses ('decoy shot'?) 1b. But wasn't Oswald seen firing the rifle from the Book Depository, and identified by someone named Brennan? Howard Brennan has already been thoroughly discredited as any kind of reliable witness. As noted by James P. Duffy and Vincent L. Ricci (5, pp. 89-90): "Brennan's detailed description of the sniper is credited by the Warren Commission with leading to Police Officer J.D. Tippit's attempt to arrest Lee Harvey Oswald. Although Brennan failed to pick Oswald out of a lineup at Police Headquarters, he later identified Oswald's corpse as the man he saw in the window. Brennan's testimony is full of discrepancies, including the fact that he said the man in the window was standing, which allowed him to estimate the man's height and weight Photos taken seconds after the shooting show the window was raised less than halfway, suggesting the shooter would have had to kneel." The curious thing regarding this instance, is that when the (Warren Commission) had the opportunity for integrity, they abused it. The original author of the section to do with Brennan was Joseph Ball, "who was extremely dubious about the testimony of Howard L. Brennan" (12, p143). Some of the reasons included (ibid.): - "In staging a reconstruction on March 20, 1964, Ball found that Brennan had trouble seeing a figure in the window, and thus it seemed doubtful Brennan could have positively identified a man in the partially opened 6th floor window, 120 feet away. - Brennan's identification was not based on prominent points in the assassin's clothes or dimensions. - Brennan's testimony contained a major error. He stated the assassin was standing while firing the rifle. Other evidence showed that the assassin fired from a kneeling or sitting position. - The fact that Brennan lies at the police lineup reflected on his general credibility" However, this chapter was rewritten by a 'Re-editing Committee' under the direction of Norman Redlich (op.cit., p142), who "gave a great deal more weight to Brennan's identification than did Ball."(op. cit. p144). Of course, in their rush to judgment (see Part IV) this sort of re-editing is entirely comprehensible. Despite this perfidy, as Walt Brown notes (6, p. 301): "The House Select Committee on Assassinations would later discredit Brennan's testimony, and his published memoir, published posthumously, would forever shatter his credibility." Note: Many Lone nut apologists and others, in their zeal for 'fairness' and 'objectivity', have been blinded to the issues insisting that Brennan's testimony amounted to a 'simple error' or 'mistake'. They refer to one of the Dillard's photographs showing the partially open windows (cf. 9a, photo section) and opine that Brennan was "simply mistaken" in his perceptions. However, this is egregious and also 'post hoc' rationalizing. (Since, else Brennan's testimony would contradict a number of other WC witnesses!) The point is, no official report repeals Brennan's testimony or calls it into question, hence retroactive interpretations (to make his observations fit the 'facts') are just that, 'retroactive interpretations'. Indeed, logically, if one is going to venture down the slippery slope of re-interpreting sworn statements, then we had better do it for all WC witnesses, for whom there exists corroborating testimony. (For example, Arnold Rowland saw a man with high-powered rifle standing a few feet back from the *southwest* corner of the building. (As opposed to the southeast corner). But "the Warren Commission treated Rowland like a liar" (Duffy & Ricci, p410). The question is - why exactly should Brennan's testimony be trusted more than Rowland's? (Recall Brennan claimed, in his memoirs, to have talked to all seven Commissioners, when in fact it was four, (6, p301) Obviously, the denigration of Rowland (whose testimony countermands Brennan's) and benediction of Brennan's, aids and abets the lone nut cause (and fulfills the imperative of the Katzenbach memo - see next Section FAQ, Pt 4). Finally, there appears to be some controversy over whether Brennan picked Oswald out of a line up. Lone nut critics of 'buff books' (which authors insist there was no line up pick) still admit that the identification was 'not positive'. In other words, they concede Brennan was going on a guess. This deflection therefore is based on pure semantics. The fact is, if Brennan could *not* make a positive ID, then (by definition) he did *not* pick Oswald out of a lineup. One either *makes* an identification or does not, there are no 'somewhats', 'halfways' or 'maybes', and one would not like to think the criminal justice system would pivot on such uncertainties, and ruin a person's life on that basis. 2. Was the rifle found a Mauser or a Mannlicher-Carcano? This remains, in my opinion, an open and unsolved facet of the case, despite the efforts of certain researchers to close it down as a 'factoid'. I simply believe that doing so is premature and counter- producive. Let's look at a number of things in turn: From (5, p403): "..four law enforcement officers connected with finding the rifle all state clearly that the one they found was a 7.65 caliber Mauser." It wasn't only Deputy Sheriff Roger Craig who made that ID. Also, Deputy Sheriff Luke Mooney, Deputy Sheriff Eugene L. Boone, and Deputy Constable Seymour Weitzmann.(ibid.) all did as well. Weitzmann, also signed an affidavit that appears on page 228 of Vol. 24 (Warren Commission Hearings). He noted in that affidavit that he and Depty. Sheriff Eugene L. Boone found a rifle on the 6th floor of the TSBD at 1.22 p.m. In his words: "That rifle was a 7.65 Mauser bolt-action rifle equipped with a 4/18 scope, a thick leather brownish-black sling over it" In Deputy Craig's words (from interview on film): "I read the words from 6 to 8 inches away. They read - Seven Point Six-Five *MAUSER*." Note - it was also Craig who stated that the spent shells all were within one to three inches of each other, and aligned in the same direction. (Same filmed interview). This is further testimony that the sniper's 'lair' filmed by Tom Alyea was a staged set up. (Not that Alyea did it, but that he filmed it- and interestingly, he was 'coincidentally' omitted from the Warren Commission's roster of witnesses. See Part 4). It stretches credibility that all *four* of these gentlemen could have erred in the same way - especially given the fact that the WC exhibit of the alleged weapon was clearly labeled 'Made in Italy' and 'Cal 6.5'. In addition, let's not forget that Weitzmann was very familiar with weapons, having worked in a Sporting Goods store. For the same reason, he was extremely knowledgeable about rifles (5, p. 499) He also had a graduate engineering degree, ensuring that attention would be paid to details (particularly a 'Made in Italy' label on a rifle, if indeed that was the rifle he first observed). In concert, we can surmise, on the basis of logic, that four separate individuals - at least one of whom was very familiar with rifles - could not have made the same basic error. This flies in the face of probability as well as common sense (particularly given Weitzmann's Sporting Goods experience). Logic rather dictates that we look at another possibility: that any 'official' acceptance of the Mauser ID was so fraught with difficulties - in linking Oswald to the 'weapon' (since the MC was purchased from a magazine ad) that it was more trouble than profit to retain it. (Especially in the wake of the 'directive' memo from Attorney Gen. Nicholas Katzenbach, in next section). Let's look at some other facts and features, and render logical conjectures: -Weitzmann's so-called 'retraction' of his original ID (in signed affidavit) occurred *after* the weapon came into possession of the Dallas PD as 'evidence'. This offered more than enough time for a convenient substitution - which could have occurred while people were still at the TSBD scene. For example, there is the documented report of E.D. Brewer (6, p32) that 'a weapon was being pulled back through the window of the SE corner of the TSBD'. Perhaps, just perhaps, Brewer was the unwitting observer to a blatant break in the chain of evidence. With the bogus (M-C) riflle being hauled into position. This cannot be discounted. Now, with the bogus (prop) in place, taken into 'official evidence', Wietzman could easily have been asked again- confronted with the prop - about his ID. Clearly seeing the 'Made in Italy' label, which the M-C- had, he had no option but to recant his earlier identification. - There is also the disturbing observation of a Mauser "casually brought into the TSBD" on November 20, only two days before the assassination (6, p263): Why was the Mauser being brought in? Who brought it into the bldg.? More importantly, why did it occur on the same day as reported 'weapons practice on the knoll'. (Ibid.) Who was conducting such practice? Secret Service? Dallas PD? WHO??? And more importantly, WHY?? AND WHY ON THE KNOLL? It was further noted that the reference to the Mauser was in an FBI report submitted to the Dallas Police Dept. (ibid.). Did they bury it? If so, why? Under *whose* specific orders? Let's also get clear that many Dallas cops at the time, were not what you'd call enlightened paragons of social integration. A number belonged to the Dallas White Citizens' Council, the KKK and other extreme rightist fringe groups. (cf, 3, 6) They would not have been enamored of JFK's forced integration policies, to say the least, and might be quite willing to follow orders from certain rich Texan segregationists who believed JFK a race traitor or worst. Like it or not, the Mauser issue remains open, as do the questions that surround it. We get nowhere by prematurely closing it, merely to assuage and appease a group that may be rushing to vindication by some process of 'consensus gathering' - in order to present a monolothic research face. (With all those who diverge from the unilateral and homogenized - read 'acceptable' interpretations, dismissed as 'crackpots' and excluded from having a voice) This isn't good enough, particularly in light of the psy ops' taint which covers this case like a sickly pall. Those who dismiss or belittle this pall are egregious, dangerously naive, dishonest or all three. 3. Were there really curtain rods? If so, what happened to them? The Warren Commission claimed that there was only a 'curtain rod story' (9a. p169) and the Oswald 'lied' i.e., that he later denied that he told Frazier he had curtain rods. However, it seems clear that by this time, Oswald already realized he was being set up. He realized if he admitted to the curtain rod claim it would be turned against him to mean he actually had possession of a concealed rifle. He probably reasoned it would be better to deny the claim, than accept a further association which could be convoluted to implicate him, particularly as he was already mired into being a full-blown patsy. What we do know is that curtain rods were indeed hung up in Oswald's room after his arrest. A photo is shown with the curtain hanging being supervised (7, p96, lower right).
