Did feds kill off the Chicago Mob?

The Chicago Syndicate has this Chicago Sun-Times classic from 2002:

A mere decade ago, the Chicago Outfit's political wing still had an address: Room 2306 of the Bismarck Hotel, at Randolph and LaSalle, the 1st Ward offices of Committeeman John D'Arco Sr. and Ald. Fred Roti, a made member of the mob. Downstairs at Counsellors Row Restaurant, D'Arco and Roti held court with mob-friendly aldermen, judges and state legislators like John D'Arco Jr. The feds installed a hidden camera at Counsellors Row and wired lawyer Bob Cooley. They caught D'Arco and Roti discussing mob business such as rigging elections, bribing judges to fix cases and greasing zoning and license deals.
