There was nothing left to flip on. They had Gotti, they were closing in on the Corrozzo faction, they had good intel on the Florida crews. Gotti couldn't have known about the cramming "internet billing scam" that was on the horizon. What info (besides obviously rolling on other families) could Gotti have provided at the time on the Gambino's? He wasn't gonna roll on One Eyed Pete or Junior, so who was there at the time that essentially would have been worth it to the Federal Government more so than Gotti finally behind bars after mocking the system for years?
I don't know what you mean by he had nothing to offer. As boss he knew about almost every racket, could back up Gravano's testimony, and could give info on the other families and their bosses. The Corozzo faction wasn't busted until December 1996, which was 6 years after Gotti was arrested. Gotti was in the same situation as Massino after Vitale flipped. Of course the feds would have welcomed him with open arms. Imagine the coup, forcing the Al Capone of their era to become a rat. That would be more embarrassing to the mafia than sending Gotti to prison.
Gotti didn't flip because he was a true gangster, just like Scarfo, the Commission Case guys, and Chicago guys who were given life.
