.watch

A neighborhood watch or neighbourhood watch (see spelling differences), also called a crime watch or neighbourhood crime watch, is an organized group of civilians devoted to crime and vandalism prevention within a neighborhood.
The aim of neighborhood watch includes educating residents of a community on security and safety and achieving safe and secure neighborhoods. However, when a criminal activity is suspected, members are encouraged to report to authorities, and not to intervene.
In the United States, neighborhood watch builds on the concept of a town watch from Colonial America.
