In any other country the vice-president would have been a prime suspect. Cui bono? Only LBJ had the influence to arrange things before the kill and the power to control the investigation after. He was extremely ambitious for the presidency. And according to JFK’s sister to be dropped from ticket in ‘64. Even if he were not dropped ‘68 was too long to wait for a man with a family history of heart disease. He was deep, very deep, in corruption and investigators were getting close to him. JFK was not coming to his rescue. After he became President that was all put to rest.
He had a history of corruption going back to his college days. None of this is proof but it is just a smidgen of the evidence.
You're so right. I was 21 at the time and in college. One thing I specifically remember was that Life magazine, pretty much of a Kennedy house rag, ran a very much anti-LBJ article shortly before the assassination, the kind of thing anyone with an antenna as long as LBJ's would view as proof of a deadly threat. Furthermore, Bobby and LBJ bitterly hated each other, with Bobby being the one who had influence with JFK, not LBJ. LBJ would have been a complete fool not to hear the ever closer footsteps. Thus, the "Final Solution to the JFK Problem" undoubtedly became LBJ's solution, with the further advantage that he and the MSM were able to frame and framed conservatives and Republicans for the assassination.
I think I heard Robert Caro (an LBJ biographer) say that JFK hated
Johnson, and it was somebody like Mike Mansfield that showed
up with LBJ and told Kennedy "This is your running mate".
