There was a piece of video I saw years ago taken of LBJ on Air Force One when he is told Kennedy has died. Johnson doesn’t know there is a camera rolling and he gets this huge ebullient grin on his face a moment before he sees the camera and instantly puts on a more appropriate somber face. Johhnson knew and probably gave the Mob intel that let them succeed.
The last episode of the men who killed kennedy has disappeared from the DVD set as well as the internet. completely disappeared.
