I have seen simulation where there was blowback out the front that did propel a test object backwards - in 1 out of 100 attempts- but when it did, the front of the object tested was an exploded-out mess.
The first shot missed hitting behind the moving vehicle. Jacket material from the ricochet struck JFK in the back of the head and the inside front windshield landing on the floor of the vehicle where it was found. Kennedy says that he has been shot. (Hard to do if the first shot is the head shot). The second shot struck Kennedy in the back exiting below his collar. (This projectile also struck Connelly--The 6.5mm 160gr heavily jacketed round nose bullet used in the M-C can penetrate 47" inches of pine. It could easily travers two bodies). The third shot is the dramatic shot captured in Abraham Zapruder's super-8 film. All shots came from the rear.
Oliver Stone's mantra aside the forensic evidence is clear. Bodies do not respond to gunshots the way they are portrayed in hollywood--flying across rooms, etc. A head shot scrambles the CNS causing all kinds of involuntary muscle movement. The inshoot (small) and outshoot (large) will reveal the trajectory.
The only reasonable book on this subject that I've read is by Bonar Menninger "Mortal Error". Amazon Link. It documents the efforts of Howard Donahue, a ballistics expert and shooter who bettered Oswalds supposedly impossible feat, to communicate what the evidence reveals.
wrong again
there is a still photograph taken from behind that shows the moment of impact and a huge spray out the rear of his head
his brains were also on the back of the vehicle, which is what Jackie O is seen crawling out the back of the car to retrieve
if the shot came from the back, then there would have been blowout on the front LEFT of his forehead, not front right

can you send me a copy of this ‘archival’ copy of the zaprudewr film?
I am currently working on some software to remove the jerking motion of the camera- by isolating the moton of the car and centering on a stationary position of the seat of the car.
which should more clearly show the relative motion of the people inside the car.
