(The Center Square) – According to a professor who has studied public corruption, it might be a good thing that prosecutors are seeking $3.14 million in forfeiture proceeds from convicted former Illinois House Speaker Michael Madigan. Connie Mixon, professor of political science and director of the Urban Studies Program at Elmhurst University, said convictions and prison sentences have not kept many of the state’s elected officials from committing crimes up to this point. “We keep having these guilty corruption cases over and over and over again, but corruption persists,” Mixon told The Center Square.
