He was a small time hood but he also hung around police officers for probably the same reasons. To feel important.
Even if you could prove Ruby killed Oswald in order to shut him up, that still leaves the fact Oswald killed Kennedy.
Ruby shot Oswald because he thought that would make him a national hero and never be convicted, like a parent who kills a child molester,etc.
Radix is really funny on this thread, anyone who can’t see the conspiracy is an “absolute idiot”, but he made his mind up a long time ago, thinks the umbrella man is significant and definitely HAS NOT read Case Closed or Bugliosi’s book. He’s the authority here, he read a book about 20 years ago and made up his mind, with such a thorough examination of all of the evidence who can argue with him? Who is willing to taste his venom? Who will incur his wrath? Who will dare debate a man who read a book he can’t remember about 20 years ago? He will crush us. We have been warned.
