Stepping away from Brian Doyle's usual installment of nonsense, there is a really interesting thread going on at the Education Forum for a change involving Craig Bouzarth's work on Zapruder film authenticity. He is battling it out with another guy who is posting giant AI essays arguing for a fake headsnap and other things that seem impossible.
The "Just because the film wasn't altered doesn't mean there wasn't a conspiracy" responses will now ensue. Either that or charges that Mr. Bouzarth is a CIA agent.
If the film is authentic then a whole series of claims over the years fall apart. About the head wound location, about JFK and JC responding simultaneously to a shot, et cetera.
The interesting (grading on a scale here) debate for me over there is the claim that JFK was going to unconditionally leave Vietnam after re-election. For the Garrisonites - the Oliver Stone and DiEugenio types - this is critical to their conspiracy belief. It's the Rosetta Stone, the key act, to their explanation as to what happened and why. If JFK wasn't going to simply leave then the idea that the national security state, the military industrial complex, killed him because he was leaving completely falls apart. JFK *had* to be leaving; otherwise why would these powerful forces take him down?
