Yes. When I moved to Texas in 1978 I worked with a lot of native Texans. After several months I got up enough curiosity to ask them if they thought LBJ was behind JFK’s assassination and to a person they all said “Of course he was”.
LBJ was a mean old bastard that would make Hillary look like an angel.
He hated the Kennedy brothers, and was pissed he had to take the VP slot.
Murder was not beneath him...................
It wouldn’t have been LBJ’s first murder.
