Im no forensic analyst but I can see on the Zapruder film the right front of JFK's skull blown open. That is an exit wound. Full metal jacket bullets tend not to cause that type of violent expansion. Seems like a completely different type of round than the bullet that traversed the president's superior thorax, traveling through the governor, and found intact with minimal damage. It seems like common sense to me that the headshot was a hollow point or similar round. It also seems like common sense to me that a hollow point round would have expanded and caused a devastating exit wound on the anterior chest or neck of the president. I dont understand how anyone with a basic concet of terminal ballistic effects can think otherwise. Call me a conspiracy theorist, but those were two markedly different bullets.
