Secret Service men running up the knoll

[Alan Hardaker]

If the so called fatal head shot came from the rear how was it that brain matter from the President was propelled on to the rear of the car. I know nothing about the science of ballistics, so there may be a logical explanation for this apparent anomali. Other than just saying the fatal head shot came from the front and that's obviously why the brain matter was propelled in the direction of the shot.

I mean what forces of physics were at work here. How did the Presidents brain tissue go in a completely different direction to the trajectory of the shot, if the shot was from behind .
