Citizens On Watch offers a free tool to alert or notify citizens about suspicious activity based only on GPS location. Citizens out for a walk don't have to know who lives in a given house to alert them to suspicious activity. The tool provides a way of tracking suspicious persons, animals, objects, or vehicles. It is a tool populated by citizens and easily accessible by everyone.
The site is still in beta. We are looking for any feedback from the crowd for this tool using the crowd for the crowd.
