And as I've pointed out elsewhere, proposing various motives of random people and organizations has nothing to do with actually figuring out who commits a crime. That is something done with evidence. The evidence proves that Oswald did it, and he had no ties to the Fed, or LBJ, or most of the other usual suspects that get offered up.
The magic bullet explanation Specter gave is utter BS.
I saw the Zapruder film in 1978. It changed my perspective.
People around my neighborhood growing up did not talk about the assassination. They stayed completely mum.
Oswald was a patsy. No way did he make it on the front covers sans being a cover story in international newspapers before the blood stopped flowing.
