But, what about Ruby's dramatic statement to the press, that this rose all the way to the top, to powerful men, including the current President?
He got that from J Evetts Haley's book, A Texan Looks At Lyndon, which I have read. Haley kept the official story of Oswald being the lone gunman, except he added the spin that Johnson put Oswald up to it. That's all it was based on. If Jack Ruby had explicit knowledge of Johnson being involved, he would have been dead before he finished his first meal at Dallas County Jail.
It's just bait for the buffs. Don't be a baited buff. It is the lowest form of chump on the planet.
