Thud Prompts Closet Sweep
Agents arrested Pamela Phillips in her condominium kitchen on kickback charges. While handcuffing her, they heard a soft thud from the nearby walk-in closet and saw multiple open briefcases suggesting recent activity. They quickly swept the spare bedroom and closet, looking only in places where a person could hide, and found documents in plain view.
Basement Odor Triggers Sweep
Officers arrested Piper Patel inside her townhouse living room. Sergeant Ramirez noticed muddy boots by the open basement door and smelled fresh cigarette smoke rising from below. Intelligence reports linked Patel's crew to armed gatherings in that basement. Ramirez descended and briefly checked behind a stack of drywall where a person could hide.

Common questions
Frequently Asked
4
What level of suspicion justifies a protective sweep beyond the arrestee's immediate control?+
Officers must possess a reasonable belief based on specific and articulable facts that the area harbors an individual posing a danger. A mere hunch or generalized concern is insufficient.
Supporting sources
May officers conduct a protective sweep after every in-home arrest?+
No. Automatic authority reaches only the arrestee and the area within immediate control. A sweep of other spaces requires an additional, particularized safety justification tied to the presence of a dangerous person.
Supporting sources
What is the proper scope and duration of a protective sweep?+
The sweep must be cursory and limited to places where a person could hide, such as rooms, closets, or behind doors. It may not extend to containers too small for a person or become a full evidentiary search.
Supporting sources
Does discovery of evidence during a lawful protective sweep require suppression?+
No. Items observed in plain view during a valid sweep are admissible even if the underlying offense is nonviolent and the officers discover documents rather than weapons.
