The following outline is provided as an overview of and introduction to law enforcement:
Law enforcement – subsystem of society that promotes adherence to the law by discovering and punishing persons who violate rules and norms governing that society.

In North America, some of these services are called police while some have other names (e.g. sheriff's office/department; investigative police services in the United States are often called bureaus (e.g. FBI, USMS, ICE, CBP, ATF, DEA, USSS etc.).
