Boss of Bosses: The Fall of the Godfather: The FBI and Paul Castellano

The Godfather had to die. Paul Castellano was for many years the most powerful man in all of American crime: as head of the Gambino crime family, he was the "capo di tutti capi". But by 1985, he had outlived his usefulness; there were younger, more aggressive men eager to take his place. Besides, his personal behavior and his indiscretions were not only an embarrassment to his colleagues-in-crime, but also placed all of them in direct jeopardy of public prosecution for their underworld activities.
