Stops, searches, and arrests are some of the most common types of encounters that the public has with law enforcement. Each encounter also presents the opportunity for an adverse outcome, up to and including harm to officers and community members. Law enforcement agencies must ensure that all stops, searches, and arrests are made by the rights secured or protected by the US Constitution, specifically the First, Fourth, and Fourteenth Amendments, along with state and federal laws.

Ensuring stops, searches, and arrests are lawful and appropriate can help foster community trust and law enforcement legitimacy and promote a shared responsibility for addressing crime and disorder and other public safety priorities.
