Just saw one documentary which focused on ballistics and claimed that the kill shot came from a frangible round, from a secret service ar-15.
I tend to think it was just the nut, Oswald, who got in a lucky shot.
What about the witness that was grazed by a second shooter?
If you ever get to Dallas, go to the 6th floor of that building (now a museum) and look out the window. Oswald wasn't all that lucky.
You wouldn't need to be a highly trained SEAL sniper to make that shot. The average deer hunter (maybe even below average) could have made it. It was only about 60 yards.
I was amazed when I went there. I always envisioned it as some really long range shot. When I was looking out there was a guy standing next to me that said the same thing I was thinking... 'that was really close!"
It was.
I watched that documentary too and thought it was very compelling. The title was JFK: The Smoking Gun. The sole focus of it though was only the killing shot. They conceded that Oswald fired the other two shots but made no effort at all to explain his motives or possible connections. That was fair enough though, they had their story line and spent their time on that.
