As a nephew of someone who happened to be a very close associate of Lyndon Baines Johnson, this is my take on the whole thing. John and his brother Robert were allegedly involved in Marilyn Monroe's death, and LBJ used this "fact" to garner overwhelming support in favor of Kennedy's assassination. His true intentions however were most likely that he wanted to make sure that he [1] was not implicated in the "Billy Sol affair" and [2] could become president. Incidentally, if it were not for the fact that Hoover had been pulled into the scheme, Oswald might have gone down in history as a hero. Why? Because he was reporting the progress of the "plans on the ground" to the FBI on a regular basis. Unfortunately for him, Hoover was burying these reports, just as Oswald himself was being designated as the most convenient fall guy. In truth, I believe that he was a patriotic (if naive) "agency man" who gathered much useful intelligence for US interests, including a detailed report concerning operational matters relating to an electronics factory in Minsk, key Cuban assets, and of course details about a plan to take the president's life! It's a very sad twist of fate, but it just goes to show how cronyism can tarnish even the most prestigious institutions. As for official recognition of "the truth", that will probably never happen. It would only open a can of worms that nobody wants to deal with...
