The Outfit had penetrated and corrupted a key Hollywood labor union. The racket was exposed in a newspaper series in 1943, and the Mob's front man, Willie Bioff, was indicted. He and his co-defendants then ratted out their higher-ups in the Outfit. Paul (the Waiter) Ricca and others in the Outfit demanded that Nitti take the rap and go to jail as a "stand up guy." Nitti had done 18 hard months for income tax evasion previously, and he didnt' want any more time. So, he got drunk, wandered onto the railroad tracks--and shot himself in the head.
