Probably closer to the truth than you would think. The JFK assassination had very little to do with classic liberal-vs.-conservative matters. Oswald was trained at the spook base at Atsugi, Japan and had links with Naval Intel in the late '50s. Somewhere personal enemies like Allen Dulles and J. Edgar Hoover, Oswald entered the clandestine realm. If he did it alone he's the greatest post-mortem "ghost" serial killer of witnesses and those who knew too much in history. ABC is full of crap. As usual.
Kennedy was a seriously flawed man and a questionable president, a hero for liberals, etc. But an intelligent group planned and designed that little episode in Dallas. Haven't been so many post-event convenient suicides since...well...since all of Clinton's friends... [irony]
Someone has gone to extraordinarily bizarre lengths to try to get people to buy the Oswald as "lone nut"/"lone gunman" crapolla. It's safe to say Oswald did not fake JFK's autopsy photos. He couldn't have killed William Bruce Pitzer or Rose Cheramie. Too many weird and odd details in the JFK maze for one marine, whatever the marksmanship skills. There was a "badge man." There was smoke on the grassy knoll. Eyewitnesses have testified to that. There was a man with an umbrella, for God's sake. Fake myserious agents confiscated cameras and film. A powerful cabal organized this. They weren't "conservatives." Neither was LBJ. If ABC is "in" on the absurd cover-up, we can assume they share some agenda with the assassination cabal. Follow the money...connect the dots... You can't hoodwink all of the people, all of the time. As much as they try... ABC also shut down valid investigations of Clinton.
Fletcher Prouty, a loyal American, had nothing to gain by coming forward. To believe Oswald acted alone you have to asssume all those other witnesses were insane or hallucinating. Oswald is in New Orleans in 1963 with other spooks involved with Cuba. Come on...
