What consensus can be reached about how the assassination took place? What was the nature of the cover up? How are the two elements interlinked? The assassination was probably dreamt up by Texas right wingers mixed in with anti Castro Cubans and rogue Intelligence operatives. They had to get a go ahead from somebody very powerful and connected. Who was this "somebody"? Not sure at this point. One of the Intelligence guys probably served as Project Manager.
The cover-up was definitely orchestrated from somebody high up, likely either J Edgar, LBJ or both. They probably knew about the hit ahead of time, otherwise the coverup would not have gone so smooth.
BRAVO!! Mr K..... I believe that you're 100% and firing on eight cylinders....
Of course I'd say that, because what you've written could have come from my hand....
Common sense dictates that someone in a key powerful position had to have control. That person was J. Edgar Hoover.
I'm certain that Hoover with his vast network of agents and informers knew precisely who was planning the assassination, and he actively supported the plotters. That makes him an accessory before the fact, and it's obvious that he had a heavy hand in controlling the "investigation" afterwards, which makes him an accessory after the fact.
Hoover may not have known that some of his FBI agents in the south, were members of the KKK, but I doubt that he would have reprimanded them if he had known.
