The Zapruder film clearly shows Kennedy;s head being thrown back and a red mist of blood and brains appearing behind him from the shot that killed him and came from the front.
Yes
Exactly
A supersonic jacketed rifle bullet always leaves a much larger exit wound than its entry wound. If the bullet came from the front, the entry wound would have been small and in the front. Instead, the small entry wound was in the rear and the top mid-to-front part of the skull was blown off.
I have shot many animals.
That is not always the case.
Like 9/11 and TWA 800...that whole laws of physics thing again!
If it wasn't for that Damn film the CIA would have gotten away scot free without all this nonsense.
That is the main thing that makes me skeptical that Oswald was the only shooter.
There only two ways Kennedy's head and shoulders could be thrown back in such a powerful way:
1) A force from a shot fired from the front.
2) His own muscles flung him back in reaction to a bullet that enters his brain from the rear. You can kind of test this theory: Sit in a chair and lean forward the way Kennedy was after the first bullet entered his throat, then jerk yourself backwards as hard as you can and see it you think you can jerk back as violently as Kennedy's head/shoulders jerk back in the film. I've tried it, and I can't seem to jerk my head back anywhere near as violently as Kennedy's head was flung back. Try it for yourself.
I have seen the Zapruder film enhanced and the mist of blood goes forward.
There were many people near the grassy knoll who heard shots coming from behind. A reporter for a Dallas newspaper said he saw smoke coming the area behind the grassy knoll. He said it was the area where there was a bridge over the railway tracks IIRC. That was before the lone gunman in the book depository became established as the official explanation.
