In this meticulously researched classic of the JFK conspiracy genre that Library Journal calls "sensational", Mark North argues convincingly that President John F. Kennedy died as the result of a plot masterminded by Louisiana Mafia chieftain Carlos Marcello - and, more importantly, that FBI chief J. Edgar Hoover learned early on about the plan but did nothing to stop it. Hoover warned no one - not the Dallas police, not the Secret Service. His motives, North suggests, stemmed from a fervent hatred of Kennedy and fear that the President would eventually fire him.
"Good info in the Kennedy Hoover relationship"
Here's what we now know: John F. Kennedy was assassinated in Dallas by Mafia contract killers hired by Louisiana mob boss Carlos Marcello. Kennedy was killed in that city because it was the only place in the country where a crime of that magnitude could be committed without fear of punishment. Long-time 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 U.S. senator during the 1950s, had accepted bribes from the same mobsters so that they could avoid deportation.
