Also wonder about clear mob connections with Ruby.
I think Caastro is as good a guess as any, maybe better than any.
Not too long ago there was report that Johnson said that he always believed it was Castro. Makes sense. But this report here doesn't say anything about other gunmen besides Oswald and seems to suggest Oswald was lone assassin. I still have a problem with a single gunmen after seeing the zapruder film footage showing Kennedy thrown backwards after one of the shots.
Ruby? Whoever hired Oswald would have wanted to silence Oswald. Based on this report it could have been Johnson or Bobby that got the mob to silence Oswald who was going to be executed anyway. Hard to believe but possible. I would have thought Bobby would have demanded revenge.
It's hard to believe that Johnson would have based a decision about Cuba on domestic politics but never forget it was Johnson who in trying to persuade a congressman to vote for the Civil Rights Act told him to vote for it because "we'll have those "nxxxxx's" voting democrat for 200 years".
