Chicago always was a war zone, so it's not a sudden browns issue. The Italian Mafia was and still is a factor. Al Capone, John Wayne Gacy, and I think the Jewish mob, Jacob Loeb, Nathan Leopold Jr., Richard Loeb, and Nathan Leopold Sr. There was Mayor Richard J. Daley, and Mayor Richard M. Daley in more recent times. Chicago was always criminal, with murder being a feature of the place. So, its history just continues to be what it always was. Sadly, humans gonna human, being too stupid to even think about being decent creatures.
