Truth about JFK

Hoover and Dulles did not conspire with the New Orleans and Texas mafias that lost a lot of money from losing Cuba. Johnson was not installed by them after they all killed JFK in Dallas to ramp up the war in Vietnam. Johnson was not a "party boss" who basically rigged his elections to win with the help of the above groups. There were not multiple shooters either. Jack Ruby was not sent by this group to kill Oswald. The same corrupt cabal also under no circumstance also killed RFK and MLK Jr several years later. None of the above is true.
