(I don't want to break the thread, but since you asked: the Zapruder Film and all photos and films taken of the Kennedy Assassination were doctored before most of them were returned to their owners. Some photos, etc., were never returned. The Z-Film is crap. The Secret Service man driving the limo, pulled over to the left and came to a stop. He turned to look at Kennedy. Kennedy got shot from the right front. The limo driver turned around and hit the gas. This sequence has been removed from the film in order to shield Secret Service complicity.
The photo techs did a lousey job.
