Check out crime in your neighborhood

CrimeMapping.com will mash-up reported crime statistics and overlay them on Google Maps. currently it appears limited to CA, FL, and a few other states but as they bring on reporting agencies it should expand. I imagine it will always work better in a city since they keep better statistics and reports.

One of the great features that the website offers is a service that allows users to be alerted of crime in their area. If you live in one of the cities serviced by the website, you can choose to get emails when new crimes are reported in your vicinity.

This is a great way to learn about a new neighborhood before investing, or keep tabs on a neighborhood you own property in to see if it is going uphill or downhill.
