With the St. Louis Metropolitan Police Department's new free iPhone app, St. Louisans can give themselves a self-guided tour of the seedy underbelly of our city. Want to do some amateur sleuthing? The app shows you dates, times and locations of various felonies around the city, from breaking and entering to car theft to murder, so get out there and collect some evidence! There has been a recent rash of flashers along Tucker Boulevard; that might even be a fun crime spree to get the beat on. If people-watching is more of your thing, the app shows you the homes and photos of area sex offenders so you can keep tabs on them. Just don't get caught stalking a stalker, or you could end up with a CrimeReport of your own.
