True. Ruby doesn’t suggest conspiracy it screams it. Ruby, a strip club owner, sacrificed his life for Jackie Kennedy? Sure...
Ruby really was crazy. Read his testimony. It's plain nutty.
It wasn't possible for Ruby to plan his actions in advance. He was only in position to do what he did because he got lucky.
Thing about Ruby - by all accounts, everybody who knew him, they said he was absolutely crazy as a loon, AND, he was also the last person in the world to place any sort of trust in to perform anything important.
