Illinois is one of only two states (our northern neighbor Wisconsin is the other) that does not allow concealed carry of firearms by its citizens. Oak Park is one of handful of municipalities in Illinois that does not even allow its residents to own and possess guns in their own homes. Unfortunately for Oak Parkers, someone forgot to tell the criminals, who often insist on bringing weapons along to their robberies. The need for a decisive, bold response on the part of the Oak Park Police Department leadership was clear, and the brass did not disappoint. The answer is—whistles!
