nationwide. Giuliani's critics said that he arranged for people to be arrested but then dropped charges for lack of evidence on high-profile cases rather than going to trial. In a few cases, his arrests of alleged white-collar criminals at their workplaces with charges later dropped or lessened sparked controversy and damaged the reputations of the alleged "perps". He said veteran stock trader Richard Wigton, of Kidder, Peabody & Co., was guilty of insider trading; in February 1987 he had officers handcuff Wigton and march him through the company's trading floor, with Wigton in tears. Giuliani had his agents arrest Tim Tabor, a young arbitrageur and former colleague of Wigton, so late that he had to stay overnight in jail before posting bond. Within three months, charges were dropped against both Wigton and Tabor; Giuliani said, "We're not going to go to trial. We're just the tip of the iceberg," but no further charges were forthcoming and the investigation did not end until Giuliani's successor was in place. Giuliani's high-profile raid of the Princeton/Newport firm ended with the defendants having their cases overturned on appeal on the grounds that what they had been convicted of were not crimes. Mafia Commission trial In the Mafia Commission Trial, which ran from February 25, 1985, through November 19, 1986, Giuliani indicted eleven organized crime figures, including the heads of New York City's so-called "Five Families", under the Racketeer Influenced and Corrupt Organizations Act (RICO) on charges including extortion, labor racketeering, and murder for hire. 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." Gambino crime family boss Paul Castellano evaded conviction when he and his underboss Thomas Bilotti were murdered on the streets of midtown Manhattan on December 16, 1985. However, three heads of the Five Families were sentenced to 100 years in prison on January 13, 1987. Genovese and Colombo leaders, Tony Salerno and Carmine Persico received additional sentences in separate trials, with 70-year and 39-year sentences to run consecutively. He was assisted by three Assistant United States Attorneys: Michael Chertoff, the eventual second United States Secretary of Homeland Security and co-author of the Patriot Act; John Savarese, now a partner at Wachtell Lipton Rosen & Katz;
