Interesting that you mention Zapruder, Kaptain; there is now a strong school of thought amongst critics that the Zapruder film was altered/faked. Some even suggest that Zapruder himself was involved in some way, and his background and connections have been heavily scrutinized. The debate between these "alterationists" and those who think it's nonsense have served to further fracture the research community.
There are a disproportionate amount of Jews involved in this case in all areas. For instance, the people who did almost all of the "work" (i.e., coverup) for the Warren Commission were the staff, not the august members like Earl Warren or Gerald Ford. Those young counsels were mostly Jewish, including the most active members like Arlen Specter, David Belin and Wesley Liebeler. Curiously, almost all the original critics of the Warren Report were also Jewish. My early heroes Mark Lane and Harold Weisberg, along with Sylvia Meagher, Richard Popkin, David Lifton, Harold Feldman and others were Jewish. Filmmaker Oliver Stone is half- Jewish. For what it's worth.
On a similar unusual note, many of the characters connected to the JFK assassination in some way were, or were alleged to be gay. Jim Garrison alluded to this with his politically incorrect comment that the assassination had been "a homosexual thrill killing." Jack Ruby was almost certainly gay, and Oswald was rumored to be at least bisexual (one witness would laughingly refer to Ruby and Oswald as "bedmates"). David Ferrie and Clay Shaw were both gay. The most visible member of the coverup was J. Edgar Hoover, another closeted homosexual. Garrison himself had allegations leveled against him (which were almost certainly false) about soliciting underaged males. General Edwin Walker, the anti-communist zealot who has long been considered suspect by many in the research community, also supposedly propositioned young males for sex. Mark Lane has been accused of being gay by his enemies. Whatever the significance of all this, there is no question that this tiny minority group keeps popping up everywhere in this case.
