The actual story of Gotti's prison beating is pretty funny.Gotti had been paying the Aryan Brotherhood $50,000 a year for protection in the joint. He then decided that he had enough hangers-on and associates to watch his back,so he told the AB that he didn't need their services anymore.In addition,he reneged on a deal to provide one of the top AB leaders with a high-powered attorney.

Being shrewd businessmen on a par with any Mob Boss,especially a doofus like Gotti,the AB formulated a unique marketing strategy.

A black bank robber (who was up for parole),Walt Johnson, picked a fight with Gotti and lumped him up. After the beating,Gotti went crawling back to the AB for payback. "Why certainly Mr. Gotti,we can take care of Mr. Johnson,but it will cost you $100,000."

Gotti paid the money,and miracle of miracles,Johnson's parole goes through,and he leaves the prison. The AB Customer Service Department informs Gotti that they can't fulfill their end of the deal,but his deposit is non-refundable.
Of course,Mr. Gotti could always meet with their Dispute Resolution Advisor in the mop closet on the third tier Mon-Fri between midnight and two AM.

Now anyone who knows anything about the AB can tell you that nobody,I mean nobody, is beyond their reach,inside or outside of prison.The AB hustled Gotti and got away with it.
