Law Enforcement agencies have a history of trying to pit Mafia agaisnt Black Panthers, Klu Klux Klan, and other groups they are targeting. Aryan Brotherhood would not use Black inmate for revenge. That inmate who attacked Gotti in yard was on own, or provoked by someone, not AB though. If Gotti had offered money for protection, it would have made him a bigger target for everyone inside. How would he get the money to them is one thing, another issue. You can't deposit thousands of dollars into other inmates commissary fund.
