Interesting link.
Very interesting that he confirms the last fatal head shot came from the right front, also known as the grassy knoll.
Most folks who watch the Zapruder films agree with that, but there are a few hard core Warren spporters here who call it balderdash.
It would be MUCH, MUCH harder to pull something like that off today. Cell phones everywhere. Security cams everywhere.
Personally, I have no doubt JFK was a conspiracy. To think that a bumpkin like Oswald could pull off three of the hardest shots in history is simply ludicrous.
That "bumpkin" was a former Marine.
Two of your "most difficult shots in history" were with a scoped rifle at about 60-80 yards. The other one was a miss. If that is some sort of unprecedented feat, you need to run around during deer season and tell all those carcasses tied to people's bumpers that they can't possibly be dead.
The problem ain't what you know. It's what you know that ain't so.
