Here's a theory I've been rolling around in my head lately. That autopsy photo that shows the top of the president's head, the one with a dark round spot in the hairline, has bothered me. It's probably nothing because I simply cannot imagine the autopsy personnel completely overlooking it and saying nothing about it. It doesn't appear on the autopsy face sheet. So it was probably something innocent. What, I don't know...a clot? A speck? It just sure seems perfectly round to me though.
