November 22nd was payback for the Bay of Pigs and to prevent the audit of the (Not-)Federal Reserve.
This was after the labor unions tied to the mob had ensured JFK's victory in the 1960 election in the State of Illinois by arrangement with JFK's dad. Robert Kennedy was an out of control double-crosser with a hate on for the Italians.
Marcello hired a French sniper who made the kill shots from under a sewer grate at the side of the motorcade route at Dealey Plaza.
From Wikipedia:
In his 1994 autobiography Mob Lawyer, attorney Frank Ragano says that he relayed a message in 1963 from Teamsters Union leader Jimmy Hoffa to Marcello and Santo Trafficante, the Mafia boss of Florida, urging the two Mafia bosses to kill Kennedy.[23][24] Ragano later claimed that four days before Trafficante died, the mob boss described to Ragano how he and Marcello organized the murder of President Kennedy.
1) Cubans - Bay of Pigs, Radio Swan or the whole Russian nuke thing. The stench in the background is the CIA.
2) Diem family. After generations of political games, the Diem family finally seized the reigns of power in Vietnam. He wouldn’t dance to Kennedy’s tune, so that smell again...
3) Your point - The Bankers. Doing away with the Fed and just printing money as it was needed... That wasn’t going to end well, no matter what.
4) He was going to cut off the CIA budget. The ultimate rice bowl push-back...
5) The Generals - JFK damn near started WWIII at least twice. Someone had to do something (see books at the time like 7 Days in May is just one of many - some published before JFK departed)
6) Pissed off husband - John and Bobby both here...
7) The Mob. Plenty to make this believable....
The list could go on. Racial strife and riots, Johnson and his greedy band of cutthroats, the list could go on for pages. Despite the granting of sainthood by the media, there is much to dislike about the guy...and the entire Kennedy clan, truth be told.
