Closet Sweep After Thud
Regulatory agents arrested Dana Lee in her condominium kitchen on kickback charges. Upon hearing a soft thud from the nearby walk-in closet while handcuffing her, two agents quickly swept the spare bedroom and closet, looking only in places where a person could hide. They found incriminating documents in plain view during the brief check.
Basement Check After Arrest
Officers arrested Autumn inside her rented townhouse on assault-related charges. Sergeant Ramirez noticed muddy work boots near the open basement doorway and smelled fresh cigarette smoke rising from below. He descended briefly to look behind a stack of drywall where a person could hide, finding only construction materials.
Den And Rec Room Sweep
Detective Harris arrested Luis just inside his townhouse door on phone-cloning charges. Officers walked through the den and into the closed-door basement rec room after noting signs that an armed associate might be present. They limited the check to spaces where a person could hide.

Common questions
Frequently Asked
4
What level of justification supports a Buie sweep beyond the arrestee's immediate control?+
Officers need a reasonable belief based on specific and articulable facts that the area harbors an individual posing a danger to officers or others. The belief must exceed a mere hunch and must be tied to concrete observations such as sounds, odors, or recent signs of occupancy.
Supporting sources
How long and how extensive may a protective sweep be?+
The sweep must be quick and cursory, lasting only as long as necessary to check for persons. Officers may look only in places where a person might hide and may not open containers too small to conceal a human being.
Supporting sources
Does discovery of evidence during a valid Buie sweep require suppression?+
No. Items found in plain view during a lawful protective sweep are admissible even if the underlying offense is nonviolent. The sweep's safety purpose does not become invalid merely because evidence appears incidentally.
Supporting sources
Can generalized intelligence reports alone justify a Buie sweep?+
No. Reports of past patterns must be combined with contemporaneous, particularized facts showing a person may presently be present and dangerous. Signs of recent activity such as warm food or fresh odors can supply the needed particularity when paired with other indicators.
