Beginning in January 1988, Gotti, against Gravano's advice, required his "capos" to meet with him at the Ravenite Social Club once a week. Regarded by Gene as an unnecessary vanity-inspired risk, and by FBI Gambino squad leader Bruce Mouw as antithetical to the "secret society", this move allowed FBI surveillance to record and identify much of the Gambino hierarchy. It also provided strong circumstantial evidence that Gotti was a boss; long-standing protocol in the Mafia requires public demonstrations of loyalty to the boss. The FBI also bugged the Ravenite, but failed to produce any high-quality incriminating recordings.
