A real-life Mafia kingpin from approximately 1970 to 1975, Nicky Barnes headed an underground organization in New York City known as "The Council," through which he peddled cocaine and heroin en masse to the American public. Barnes surrounded himself with scores of underlings and right-hand men, creating a shield of substantial protection and isolation -- both from the law and from violent intra-organization betrayal. In time, however, one of Barnes' drug runners did snitch, which brought his kingdom tumbling violently to the ground -- and Barnes himself became a turncoat for the FBI, informing on the associates who helped make him a power player. Barnes cropped up in 2007 as the subject of Marc Levin's documentary Mr. Untouchable, in which the former Cosa Nostra giant discusses his life on-camera with his face obscured. The film followed the publication of Barnes' autobiography by approximately one year.
