"Back and to the Left"
In the Zapruder film, starting with the third shot at frame 313, the upper right part of Kennedy's head blows out forward, and his head lurches back and to the left. According to the conspiracy theorists, there is no way this shot could have come from the book depository; it had to have come from the front, perhaps from the grassy knoll. The reason why, they say, is that the bullet entered from the front of JFK's head and pushed his head backwards. A shot from behind, they tell us, would have propelled his head forwards.
This is completely wrong in every possible way. Bullets do not make such a splattering when entering, only with the exit wound. So this immediately rebuts the claim—an exit wound in the front means a shot from the rear.
Not only that, but as Kennedy's head was angled down at the time of the shot, the only clear shot of his head was from the book depository. A shooter trying to hit his head from the front would have to be under the floor of the front seat!
Also, there's no reason why a shot from the rear would move the head forward. It's a classic image in movies, where the hero shoots the bad guy and the bad guy is thrown backwards, but it just doesn't work. This was confirmed in Episode #25 of Mythbusters in which not even the most powerful firearms pushed the human-sized target in the direction of the shot. The reason is obvious if you understand basic Newtonian physics: since for every action there is an equal and opposite reaction, a shot that pushes the target in the direction of the shot must push the shooter back by a comparable amount.
Actually, that same Newtonian principle explains why JFK's head would have moved towards the shooter. The bullet doesn't meet much resistance as it enters and is going pretty much the same speed when it exits, but as it exits it also takes lots of pieces of skull and brain with it. This makes a kind of jet blast which propels the head in the opposite direction. This effect is easily confirmed by wrapping a melon in one-inch fibreglass tape and shooting it with a high-powered rifle. The melon actually moves toward the shooter. This demonstration was devised by Dr. Luis Alvarez, a friend of JFK, and was demonstrated by Penn and Teller in their book How To Play With Your Food and again on an episode of Bullshit!
Finally, in the Zapruder film frame immediately before Kennedy's head lurches back, it's possible that Kennedy's head is lurching forward. Again, this is consistent with being shot from behind -- the initial entry impact would push Kennedy's head forward, and the exit-wound "jet effect" would push Kennedy's head backward immediately thereafter.
hmm .. thats interesting considering Kennedy had an exit wound at the back of head . :D
