"Jack Kennedy’s refusal to support the Bay of Pigs invasion angered certain people.

The gusanos in Miami were angry because Kennedy stood by while their children died on the beaches.

The CIA was angry because the President had castrated their battle plans.

The Mafia was angry because they had thrown their support behind Kennedy at election time. In exchange, they had expected to recoup their Havana hotels, brothels, and casinos after the invasion. Now, there would be no invasion, no overthrow, and little Bobby Kennedy was hauling them into Congressional hearings.
Jack Ruby curried favor with them all." — Gates of Eden http://bit.ly/YHTlcM : a story of resistance, rebellion, and love
