Seems you are the one with deaf ears and blinkered eyes, not me. The autopsy sheet did not show any wound to the top of the head. The doctors at Parkland didn't see a wound to the top of the head.(How strange is that?) Only the photos of the autopsy (dubious at best) and Humes says that there was. And that was after the arrival of the body at Bethesda.
Ray - does it really matter? If you strongly believe, as I do, that there was a conspiracy, then the basic proof for that is the Zapruder film. If you believe, as I and others do, that Oswald could not have pulled off the shooting feat that the WC says he did, then it's pretty much a done deal. There *was* a conspiracy. Period.
Quibbling over "where was the top of the head blowout" and all of the other stuff is ridiculous. Forget the kitchen sink mentality and move on knowing that there was a conspiracy - and there is no one on this Earth that can really do anything about it. The only thing that would change things is if there was a POTUS who came in and announced officially and for the record that "There was a conspiracy" and we all know that will never, ever happen. At least not in our lifetime.
