Toward A JFK Assassination Theory 
by Martin Shackelford (11-5-96)

I'm not sure I have a specific theory, as I'm trying to keep as open a
mind as I can as new evidence comes out. Some things which look possible,
given what I've seen so far:
1) Some intelligence people (David Atlee Phillips, George
DeMohrenschildt, etc.) were involved at some stage with Oswald; whether
they were involved with the assassination remains obscure.
2) Lyndon Johnson appears to have had some degree of advanced knowledge
of the assassination, according to his mistress; his former crony, Billy
Sol Estes, says LBJ, his aide Cliff Carter and their "machine" assassin
Mac Wallace were involved (Wallace murdered Agriculture Dept. inspector
Henry Marshall in 1962; Marshall was investigating Billy Sol Estes;
political maneuvers got the death declared a suicide). 
3) Anti-Castro activists may have played a role; attention has focused on
the DRE, a group with ties in Miami (including to E. Howard Hunt), New
Orleans (Carlos Bringuier and INCA, which was involved in publicizing
Oswald's activities there) and Dallas (Sarita Odio, a group that met on
Harlandale, etc.); Guy Banister, who employed Oswald in New Orleans, was
involved in anti-Castro gun-running. 
4) Mob figures appear to have played some role (Jack Ruby obviously
included); advance knowledge of the assassination was circulating in Mob
circles (Santos Trafficante, Carlos Marcello), including at lower levels
where it blended with anti-Castroites (Rose Cheramie, a prostitute
traveling with an anti-Castro leader, almost gave the plot away two days
before the assassination when arrested in rural Louisiana). 
5) There is much evidence pointing to the involvement of Texas oil: (the
gathering held the night before the assassination by  oilman Clint
Murchison, which included LBJ, J. Edgar Hoover, John McCloy--later of the
Warren Commission, and others, and after which LBJ told his mistress the
Kennedy's wouldn't be bothering him after Nov. 22; the involvement of oil
industry people throughout (George DeMohrenchildt was an oil geologist
with high-level oil industry ties, who worked for a top LBJ backer in
1963; many of the Dallas White Russians who befriended the Oswalds were
oil-connected, or tied to defense industry-- like the Paines, where
Oswald's wife lived; DeMohrenschildt told friends that oilman H.L. Hunt
was behind it).
6) The confusion enters in because many of these groups blend together: 
       Oil man Hunt had ties to the Chicago Mob; Murchison had joint
business ventures in Louisiana with Carlos Marcello. Oilman
DeMohrenschildt worked with the CIA.
       The Mob guys and the oil guys put much money into the anti-Castro
cause.
        The CIA used oil industry jobs as cover, worked with the Mob, and
heavily supported anti-Castro groups like the DRE (and worked hard to
keep it a secret, even later). 
      Even with all this, however, this trend toward a blended theory of
the assassination is much more coherent than the literally dozens of
exclusive theories of past years.
