Depends on what kind of crime you mean? The Chicago Police Department has several different reports in pdf form that you can download to view. Sure, they're just numbers, but they're pretty easy to understand. Of course if you don't know which district is which, this page will help you determine the police commissioner for that district (sometimes with photos), give you a map of the area, and even provide you with neighborhood alerts. It's a good way to keep an eye on what happens in your 'hood that doesn't make it into the news.
