Lyndon Johnson was a right winger who'd been in the USSR? I n ever knew that, but it does explain a few things about his presidency....
Back in the mid 1980s I spent several weeks in Dallas going through a training program. On the first day each person stood up, introduced them self and gave a brief talk about who they were etc.
One guy, one of the few actually from Dallas, mentioned that he had known Jack Ruby pretty well.
A week or so later 5 or 6 of us were having lunch together and someone asked him about Ruby. It turned out he really did know him very well. He admitted he didn’t know more than anyone else about the assassination except that Ruby was higher up in the underworld than he is portrayed. He is always presented as just a guy on the fringes of the Mafia.
