Mafia Commission Trial: The Mafia Commission Trial (February 25, 1985 – November 19, 1986), officially known as United States v. Anthony Salerno, et al., was a criminal trial in New York City, United States.  Using evidence obtained by the Federal Bureau of Investigation, eleven organized crime figures, including the heads of New York's so-called "Five Families," were indicted by United States Attorney Rudolph Giuliani under the Racketeer Influenced and Corrupt Organizations Act (RICO) on charges including extortion, labor racketeering, and murder for hire.  The case struck a blow against "The Commission," a loose organization of the New York Mafia organizations that met to resolve disputes or discuss criminal activities, sometimes likened to organized crime's board of directors.  "Time" magazine called this "Case of Cases" possibly "the most significant assault on the infrastructure of organized crime since the high command of the Chicago Mafia was swept away in 1943," and quoted Giuliani's stated intention: "Our approach... is to wipe out the five families."
