This special, two-hour INVESTIGATIVE REPORTS details the many factors that have contributed to the decline of the old guard of organized crime, and profiles the new gangs that are filling the void. Extraordinary interviews with key players open a rare window into this dark world: "Tarzan" tells how he brokered a deal to deliver a Russian submarine to the Cali drug cartel; and Jim Moody, the head of the FBI's Organized Crime Division, explains how Asian gangs have blended high-tech internet crime with traditional drug and human smuggling to become a major, fast-growing (and tightly-knit) force.
