Law enforcement is the activity of any law enforcement agency, which is any organization that enforces the laws of one or more governing bodies, or an organization that actively and directly assists in the enforcement of laws. In doing so, law enforcement agencies assist governments in maintaining the peace between and safety of their subjects. A person authorized to enforce the law is some times generally referred to as a law enforcement officer, and they can also be referred to as agents. When the law enforcement officer is also responsible for public safety and social order, the person is typically called a police officer or constable. The following outline is provided as an overview of and introduction to law enforcement.
