I always found it interesting about Jim Garrison and why would a New Orleans District Attorney be investigating the assassination of a U.S. President who was assassinated in Dallas, Texas. Which is about a thousand miles or so from New Orleans. And spend ten years of New Orleans taxpayer dollars on this investigation an investigation that was under the jurisdiction of the Dallas PD and the FBI. And I don't believe Oliver Stone's JFK movie from 1991 which I've seen several times, has ever made that clear. If you want to know why Oliver Stone is such a conspiracy theorist, is because of serious people like Jim Garrison who come up with these incredible theories. Maybe its just me, but you would think a big city District Attorney like Jim Garrison would have enough crime cases of his own to investigate.
The only conspiracy theory that I believe is worth considering, that any serious person with respect on these issues, someone like Robert Blakey, who was the Chief Counsel of the House Assassinations Committee in the late 1970s that looked into the JFK assassination, is the theory involving organized crime. Especially the Italian Mafia in America in Dallas and Chicago in particular. They clearly wanted President John Kennedy killed and would have had the access and power to pull it off. And Lee Harvey Oswald, who wasn't interested in his own personal safety and freedom, would have been the perfect assassin for them. Not saying that the Italian Mafia did have Kennedy assassinated, but they could've done it if they wanted to pull it off. And the Jack Ruby and Lee Oswald connections, I believe give this theory credibility.
I think its obvious that Lee Oswald was the assassin who killed President Kennedy. It was his gun, he worked at the Dallas Book Depository, he had the means, motive, access, he could pull this off and was a good enough shooter to do it. The only question here is did anyone put him up to it. Was this a one-man operation, or were there others involved. Like members of Chicago or Dallas organized crime. Jack Kennedy, had plenty of enemies on the Far-Right in Dallas and perhaps Texas as a whole. The Far-Left especially Communists like Lee Oswald, hated him as well. The Italian Mafia hated Kennedy, because his administration was serious about putting them out of business. After the Mafia helped Kennedy get elected president especially in Chicago in 1960. With all of these factors its hard to believe that one little loser could have pulled off this assassination by himself. Which is how these conspiracy theories come about.
