I was convinced Kennedy was shot in the head from the front after listening to Dr. Robert McClelland describe in detail the entrance bullet hole at the top of his forehead near the hairline, and the large exit wound in the right rear skull. He was convinced of this fact and said he would be for the rest of his days.
Dr. McClelland examined the head wound in detail as the other doctors were frantically trying to maintain the president’s heartbeat and respiration.
Absolutely. Also the ambulance driver, Aubrey Rike, who described what he felt when he put his hand under JFK's head to do the standard lift to transfer a body from one stretcher to another.
The idea that the President's head would have flown backward from a shot that impacted the back of his head is preposterous.
I'm by no means a gunshot expert, but the impact of the bullet to the front of JFK's head is so violent, with brain matter exploding backward and upward, that to my semi-trained eye (I'm an engineer who started out as a physics major, and I do image analysis every day for my work) looks like it could have been an explosive projectile, just as the associate of Lucien Sarti stated.
