As for the head flying backwards watch the video in post 27.
Kennedy’s head reaction is consistent with a bullet fired from BEHIND.
If only Kennedy’s head went the OTHER WAY, I would have to say it’s a conspiracy.
Every single time the evidence is analyzed, it points to Oswald.
People have been screaming for 45 years that Kennedy’s head movement MUST COME FROM FROM THE FRONT!!!!!!!!!!
They are 100% wrong, another persistent MYTH that 99% of the conspiracy crowd call a fact, never mind that PHYSICS show the shot came from behind.
