John Gotti, reputed godfather of the powerful Gambino crime family, is confident of overcoming charges he ordered the shooting of a labor leader who ransacked a Mafia-run restaurant. "I give you three-to-one odds I beat this case," he told an army of arresting officers Monday, sources told the New York Daily News. "Did I every worry yet? I have nothing to worry about," Gotti said after his federal court arraignment. He's free on $100,000 bail.
