Protective Sweeps in Minnesota: What Police Can Search

What a Protective Sweep Is

A protective sweep is a brief inspection of a premises, incident to an arrest, to ensure officer safety by checking for other people who could pose a threat. It comes from the U.S. Supreme Court's decision in Maryland v. Buie. Crucially, it is justified by safety, not by a desire to find evidence.

What this means for you: The purpose defines the limit. A sweep is for finding people who could be dangerous — not for searching drawers, containers, or anywhere a person couldn't hide.

The Two Tiers

Buie established two levels:

• Immediately adjoining the arrest. Police may, as a precaution and without any particular suspicion, look in spaces immediately adjoining the place of arrest from which an attack could be launched.
• Beyond the immediate area. To sweep further into the home, police need reasonable, articulable suspicion that the area harbors a person posing a danger. A broader sweep without that suspicion is unlawful.

What this means for you: A sweep that ranged through the whole house without facts suggesting a dangerous person was hiding is a strong candidate for challenge.

Scope: Only Where a Person Could Hide

A protective sweep is limited to places large enough to conceal a person, and it must be brief — lasting no longer than needed to dispel the safety concern and complete the arrest. Officers cannot open small containers, drawers, or anything too small to hide a person. If they do, they've exceeded the sweep.

What this means for you: Evidence found in places a person couldn't hide — a small drawer, a wallet, a container — generally cannot be justified by a protective sweep.

What Can Be Seized During a Lawful Sweep

If, during a properly limited sweep, officers see contraband or evidence in plain view, it may be seizable under the plain-view doctrine. But that depends on the sweep being lawful in the first place and the plain-view requirements being met. An unlawful sweep taints what it turns up.

How It Connects to Other Doctrines

Protective sweeps intersect with search incident to arrest, plain view, and warrantless home entry. A challenge often examines whether the arrest itself was lawful, whether the sweep stayed within its tiers and scope, and whether anything seized truly fell within plain view.
