This is just a comment. I went to the web site "SECRETS OF A HOMICIDE" by Dale K. Myers and printed out entrance wound and exit wound "cartoon characters" of JFK the cut out the entrance wound and traced it over the exit wound. To my shock the trajectory of the bullet seems to be traveling at a downward angle from the throat to the back at about 10 degrees. Remembering that Mr. Myers entire idea is to prove the opposite. If this is so why didn't he put the who thing togeather. At least I had the intelligence to do this. Although I am far from an expert one has to examine the details of any theory so thus far with his OWN EVIDENCE the contrary seems to be my conclusion.
Happy New Year, marksw. Interesting that you found and revived this thread. When I was a kid, I believed wholeheartedly that JFK's assassination was carried out by a conspiracy. It was only after some of the autopsy photos became public -- and I was a much better educated and informed adult -- that what's on the Zapruder film became obvious to me.
It unmistakably shows that the right front portion of JFK's head explodes outward and upward. It is a massive exit wound. The fatal shot came from somewhere behind JFK. Once I realized that the cottage industry that had sprung up about the assassination was essentially lying to me, it became much hard to trust any conspiracy theory.
