A beat cop is a police officer who walks, rides, cycles, or drives in a specific neighborhood, known as a “beat.” Because the officer routinely patrols in the same area, he or she becomes well-known in the community, creating a positive relationship between law enforcement and the community.
Neighborhood residents will usually feel comfortable approaching the beat cop to talk about issues in the community, and they may be more inclined to report problems when they feel like they have a personal connection with the department.
A person who sits in a chair behind a computer and leads people or at least attempts to, instead of doing it in person. Usually complains about government, organization, military, political, or religious events through blogs, forums, and social networking sites.
