Case law

Maryland v. Buie (1990): How Far Can a Protective Sweep Go?

The arrest is made in the living room. How much of the house can you clear? Maryland v. Buie draws two very different lines.

What did Maryland v. Buie decide?

Incident to an arrest in a home, officers may as a precaution and without probable cause or reasonable suspicion look in closets and other spaces immediately adjoining the place of arrest from which an attack could be immediately launched. A sweep beyond those spaces requires articulable facts that would warrant a reasonably prudent officer in believing the area harbors an individual posing a danger. Either way the sweep must be a cursory visual inspection, no longer than necessary to dispel the suspicion and to complete the arrest and depart.

What does Buie allow?

  • An automatic look into closets and spaces immediately adjoining the arrest location
  • A broader sweep of the residence on articulable facts suggesting a dangerous person is present
  • Seizing contraband seen in plain view from a place you’re lawfully entitled to be during the sweep

What does it NOT allow?

  • A full search for evidence under the banner of a sweep
  • Opening drawers, containers, or anywhere a person could not be hiding
  • Continuing the sweep after the arrest is complete and there’s no longer a basis to remain
  • Using the sweep as the reason to enter — Buie presumes you’re already lawfully inside making an arrest

How it plays out on the street

Two rules, and reports routinely blur them. The adjoining-space look needs no justification, so say plainly that the closet was immediately adjoining. Everything past that needs facts you can name: a third car in the driveway, a voice from upstairs, the caller’s report that two men entered. Then keep it to what it is — looking for people, cursory, and over when the danger is dispelled. Anything you open that a person couldn’t fit inside is a search, not a sweep, and it’ll be litigated as one.

Frequently asked questions

Do you need suspicion for a protective sweep?

Not for spaces immediately adjoining the arrest location. A sweep beyond those spaces requires articulable facts that a dangerous person may be there.

Can you seize evidence found during a protective sweep?

Yes, if it's in plain view from somewhere you're lawfully permitted to be during a properly limited sweep.
