Totally, I have never seen a gunshot where the target (JFK) fell in the same direct that were shot from. He fell back towards the book depository not forward after the head shot. I do not have a theory of who did it, but it was not one man with a bolt-action rifle. There had to be at least 4 shots.

Check the film frame by frame. The initial movement was forward and to the left.
