What's in your neighborhood?
Criminal Searches provides the scary-but-useful data on how many crimes are committed in your neighborhood. It's all culled from public records, and is presented as a Google Maps mashup. You can restrict your search to sex offenders, search on a specific name to get a criminal history, or do a general search for criminals by city or ZIP code. This kind of data is certainly not for the faint of heart but can be useful in assessing the safety of your neighborhood.
