I can't imagine any of the Genovese higher ups flipping, especially the ancient guys like Quiet Dom and Matty. As far as the under 60 crowd, Barney would cut his own throat before cooperating.

Then you have to look at the guys in that administration who are already doing life (like Angelo Prisco and Little Jimmy). They're the real tough guys. They'll never flip. Never.

There are others, but those guys just jumped into my to mind first.
