Online community shares local police reports

The Medford Transcript of Massachusetts sheds light on a new community that shares local information from the police department on crimes taking place in specific neighborhoods. CrimeReports.com takes call logs from local police departments and provides the crime data online. Individuals can sign up to receive daily, weekly or monthly updates about the crimes that have taken place in their neighborhoods.

This kind of community intrigues me. It combines both online and offline communities for the benefit of the people involved. What do you think about online communities like this?
