Creative Speculation

The wounds match up perfectly with the trajectory from the TSBD. This was studied extensively for the HSCA. They looked at autopsy records and angles and trajectories and the shots all came from behind from a cone that centres on the sixth floor window.

There is no such police recording. There never was such a police recording. There was a claimed recording that was purported to be evidence of a fourth shot. It wasn't, the motorcycle it came from wasn't in the motorcade, there was no police motorcycle in the area it was supposed to be recorded in at the time (there are films and photos that show there wasn't).

Oswald took the shot he had, which was at a range of less than 100 yards on a target moving at around 12mph and directly in his line of sight. From his point of view, on that trajectory, the relative movement would have been very little.

There are no credible witnesses reporting any man on the grassy knoll. Even if there were it wouldn't mean much of anything because the shot that killed Kennedy came from behind, from the TSBD. If a shot had come from the grassy knoll it would have entered the right side of his head and probably blown out the left side of his head (and, probably would have gone on to kill Jackie, given their relative positions). This did not happen.

A pressure wave from the bullet passing through Kennedy's head made it explode. It was very messy and it sprayed blood and brain matter in, basically, all directions. The major direction of blood and tissue spray, however, was forward, not back (and Kennedy was in a moving car).

No-one is ignoring anything; the actual evidence contradicts all of these claims.
