The Zfilm shows the President being shot in the forehead and the back of the head literally popping off. This visual fact is corroborated by multiple eyewitnesses.

As 50th Anniversary Of Assassination Approaches, Surgeon Who Treated JFK Remembers « CBS Philly
Two other doctors were already treating Kennedy, Dr. Perry and Dr. Jenkins, and they ordered Dr. McClelland to hold the patient’s head.
