Stephen Corso was an accountant with a vicious gambling habit when he got into trouble and went to work for the FBI. The result: He helped make the case against the "Mafia Cops" and in the process slipped inside the Las Vegas underworld.
Despite his efforts, he was still sentenced to a year in prison. That's more time than some "killer" informants have received.
