Have you seen this? My uncle is the FBI agent mentioned in Bob Vernon's testimony. He has since retired.
Yes, I saw it before at Bob Vernons house in Houston. I just went and looked at an official copy of the Zapruder film and at normal speed it does look like the driver turns and fires a pistol shot at JFK's head. However, at slow motion, it does not. Take a look at the Zapruder clip on your entry in this thread and tell me what you think. The drivers head is facing JFK at the moment the bullet strikes him and it " appears " as if he has a .45 Auto in his left hand. I'd be interested in your reaction.
