John F. Kennedy was assassinated in Dallas by Mafia contract killers hired by Louisiana mob boss Carlos Marcello. Longtime local district attorney Henry Wade, an LBJ crony who would have sole jurisdiction over the prosecution of those responsible, had been corrupted by the local Civello crime family. Lyndon B. Johnson, while a US senator during the 1950s, had accepted bribes from the same mobsters so that they could avoid deportation.With incredible detail and documentation, Mark North pieces the puzzle together to reveal how, in late 1961, US Attorney General Robert Kennedy and his brother John, who hated LBJ, initiated a covert Organized Crime Task Force investigation of the Civello mob in Dallas. Johnson, through Wade and local federal officials he had placed in power, learned of the plan and cooperated with the Civello mob to have JFK killed.
