Governor Conallys wife did it with a silenced Beretta. She worked for Castro.
Jackie did it because she was tired of JFKs fooling around.
Nixon did it because he was pissed about losing the election.
A Dallas English teacher did it because he was tired of the Kennedys subsituting h's for r's.
Jack Ruby did it. For the dancers.
Zapruder did it with a gun disguised as a movie camera.
None of these are as ridiculous as the idea that Oswald acted alone. Sure, he shot Kennedy and was no doubt encouraged to do it. He was a known whacko roaming Texas streets passing out phamplets for a communist dictator. He was recruited and a back up shooter was there to make sure of the job. Like the man said in Die Hard, if you steal 600 million dollars they WILL find you. (unless they're sure you're dead.) If you kill the president, they WILL find you unless they're sure you're dead.
