Law is a competitive business. Always has been.

Selwyn Raab, at the end of "The Five Families," observed that, after Giuliani won the Commission case, US Attorneys all around the US were falling all over themselves to use RICO to nail Mafia big shots and cover themselves with glory. Then 9/11 went down and FBI resources were diverted to catch terrorists--they were the Mafia's "competitors" for FBI attention.

Another result of the Commission case was that state and local law enforcement wanted their share of glory, and the bigger the prize, the bigger reward for law enforcement. The FBI, the NYPD Gambino Squad, and the NY State special task force collided with each other chasing and bugging Gotti. The entire Federal prosecution team was rewarded with promotions and judgeships.

Gotti was the last genuinely Big Name in Mafia for law enforcement. No more big names, no more big rewards. Look how many people who post on this board keep asking who's in charge of this or that family. FBI probably knows, but where's the incentive for them to spend time and money catching guys the public knows nothing about?
