Just afew points....Jack Ruby who killed Ozwald before a trial is often shown on tape talking about..."you'll never know the real truth..." etc. But on the Net I found the WHOLE transcript. Jack Ruby was VERY mentally ill. He goes on to explain that these "forces at work" are the John Birch society, anti-Communist anti-Jew Club. He believes they are out to get him because he's Jewish. He changed his name Rienstien to "Ruby." His lawyers wanted him declared insane because of his ramblings about Jewish conspiracies. His mother was in an insane assuylum. He later claimed he wasn't sure why he killed Oswald it was "spur of the moment" as he left his beloved dog in his car outside...he would ramble on for hours about how these groups were out to get him to incriminate and destroy the Jews world wide.
No conspiracy....just a crazed guy! Interesting that Ozwald had counselling for major mental problems growing up!
