The Racketeer Influences and Corrupt Organizations Act, commonly known as “RICO,” was passed by Congress in 1970 as part of that year’s Organized Crime Control Act. It was designed to reach not just the foot soldiers of organized crime organizations, but the crime bosses themselves.
Although it did that directly by allowing charges to be brought against the leaders of “criminal enterprises,” it also did so indirectly by allowing prosecutors to go after low-level criminals and even drivers, doormen, etc. with threats of hefty, 20-year felony sentences and offers of reduced-sentence plea deals in exchange for turning state’s evidence against the mob bosses.
Such tactics work. Faced with the potential of decades in prison, many “loyal” foot soldiers—particularly those who merely observed rather than engaged in crime—find that the price of continued loyalty is simply too steep. So they sing. They implicate mid-level mobsters, who then sing even more loudly to implicate the bosses. The most famous example of this is the Five Families case in New York in the 1980s, prosecuted by then-U.S. Attorney Rudy Giuliani, which led to the conviction and imprisonment of several top Mafia bosses.
