Things began to change in the mid-1980s, when the Mafia was caught in a crossfire of RICO, rats and recorded conversations. The Racketeer Influenced and Corrupt Organizations act handed mob prosecutors an unprecedented tool, making even minor crimes eligible for stiff prison terms.

The 20-year sentences gave authorities new leverage, and mobsters who once served four-year terms without flinching were soon helping prosecutors.

“A good RICO is virtually impossible to defend,” insists Notre Dame law professor G. Robert Blakey, who drafted the law while serving as counsel to Sen. John McClellan in 1970. The results proved him right.

The first major RICO indictment came in 1985, with the heads of three New York families and five other top level Mafiosi eventually convicted. It took nearly two decades, but the heads of all five New York families were jailed simultaneously in 2003.

Authorities around the country were soon using Blakey’s statute and informants against Italian organized crime in their cities.

— In Philadelphia, where the mob was so widespread that Bruce Springsteen immortalized the 1981 killing of Philip “Chicken Man” Testa in his song “Atlantic City,” one mob expert estimates the Mafia presence is down to about a dozen hardcore “made” men. Their number was once about 80.

— The New England mob claims barely two dozen remaining made members — about half the number involved 25 years ago. The Boston underboss awaits trial.

— In Chicago, home of Al Capone, the head of the local FBI office believes fewer than 30 made men remain. That figure stood at more than 100 in 1990. The city’s biggest mob trial in decades ended recently with the convictions of three old-timers for murders from the 1970s and ’80s.

— In Los Angeles, there’s still a Mafia problem — “La Eme,” the Mexican Mafia. An aging leadership in the Italian mob, along with successful prosecutions, left most of the local “gangsters” hanging out on movie sets.

— The Florida family dominated by Santos Trafficante, the powerful boss linked to assassination plots targeting President John F. Kennedy and Cuban leader Fidel Castro, is gone. The beachfront Mafia of the 21st century is mostly transplanted New Yorkers, and money generated by the local rackets isn’t kicked up the chain of command as in the past.

“You have guys running around doing their own thing,” says Joe Cicini, supervisor of the FBI’s South Florida mob investigations. “They don’t have the work ethic or the discipline that the older generation had.”

The decline of “Family values” is nothing new. Back in January 1990, a government bug caught no less an expert than Gambino boss John Gotti wondering if the next generation of mobsters was equal to their forebears.

“Where are we gonna find them, these kind of guys?” Gotti asked. “I’m not being a pessimist. It’s getting tougher, not easier!”

During the same conversation, Gotti questioned the resumes of a half-dozen candidates for made man: “I want guys that done more than killing.”

Even harder, it would turn out, was finding guys who could keep their mouths shut.
