I have long felt that it was something that should have been looked into further.
LBJ was an animal and I don't doubt for one second he was capable of orchestrating the deed.
Isn't it amazing how little play LBJ gets in the media. They kiss JFK's dead ass every chance they get but it is like LBJ never existed. I guess they know he could not stand a close look. Maybe he will get one after Lady Bird dies.
