What is arrest authority and where does it come from?

• A. Public opinion.
• B. The legal power to detain and take custody of a person, derived from statutes, case law, and agency policy.
• C. Only local ordinances.
• D. Personal discretion with no limits.

Answer: (B)

Arrest authority is the legal power to detain and take custody of a person. It comes from three main sources: statutes enacted by lawmakers that grant the power to arrest for defined offenses; case law, the court decisions that interpret those laws, set limits, and establish when an arrest is lawful (including standards like probable cause and when warrants are needed); and agency policy, which translates those laws and rulings into practical rules for how arrests are initiated, conducted, and documented within a department. Public opinion doesn’t confer legal power, local ordinances alone don’t cover every scenario, and personal discretion without limits would ignore constitutional and statutory safeguards. In short, arrest authority rests on statutory authority, judicial interpretation, and agency policy to ensure arrests are legal, proper, and accountable.
