Crime-mapping mashup SpotCrime pulls data from city police records and news sources and plots it in an easy-to-snoop fashion. Choose a city, a time frame, and the types of offenses you want to see, and you can mouse-over the pinned icons to see thumbnail descriptions, or click an item for a full read. The site claims that humans are working in the background to make sense of the data, and that incidents show up anywhere form 3-24 hours after they're reported. A good tool for checking out a potential neighborhood for moving or exploring, or just keeping up on what's going down across town.
