LBJ did have JFK killed. Watch the final chapter of ‘the men who killed kennedy’.
If you look at it as just another murder and forget he was the president , you need to ask the one question that they always ask.
Who had the most to gain ?
I actually think that Sam Giaconna wanted him dead and had the ability to do it. I think LBJ was a willing participant in the cover up that he benefitted from.
I taped that LBJ episode of The men who killed Kennedy’.when it came out on the History Channel. Then apparently the History Channel left those episodes out of their boxed set. I know you can watch it on YouTube. The evidence is overwhelming, but what clinched it for me is when I heard the actual tapes of LBJ calling and offering “condolences” to Jackie. He is clearly hitting on her, which is just sick. He had an obsessive envy and wanted to become JFK in every way.
