LBJ had plenty to do with JFK Assassination but I don' think he acted alone.
I found some notes I took while listenig to a recent episode of "Coast to Coast AM" late night talk radio.
The 5412 Committee was defined as Murder,Inc. with LBJ in charge. It was a hit team set up to kill inconvenient people. Apparently it was set up when Eisenhower was President and it was under the control of the vice president,who,at that time. was Richard Nixon.
Apparently, Jack Ruby was in the Dallas Police Department files as an informant since 1948. My Dad was feted by Jack Ruby ONCE when he was a cop and it was in the presence of other copsd but he said Ruby gave him the creeps.
LBJ INHERITED THIS 5412 C is confined to the notes I took)OMMITTEE.
The radio show guest said two persons who really wanted JFK dead were LBJ & Cord Meyer. ( I am sure there were others but this is only what I took notes on from the show.)
JFK was supposedly having an affair with Cord Meyer's wife. https://en.wikipedia.org/wiki/Cord_Meyer
He married Mary Pinchot in 1945; the couple divorced in 1958, and she was subsequently romantically linked to President John F. Kennedy. Her 1964 murder remains both unsolved and controversial.
The CIA was Cord Meyer's life and JFK was dismantling it. He shut down their mind control/psyop sectors (which resumed shortly after his death) and they apparently had something to do with formulating Operation Northwoods a false flag psyop. https://en.wikipedia.org/wiki/Operation_Northwoods
The KGB found out about the plot to kill JFK & Khrushchev sent a hitman to try and stop Lee Harvey Oswald (whom we now know was NOT the lone nut assassin and was a Patsy who never fired a shot when JFK was assassinated.) The hitman killed one of the Oswald doubles but did not stop the assassination.
