• A. When the occupant consents
• B. In response to a disturbance call
• C. When there is reasonable belief of a threat
• D. During a routine patrol

Answer: (C)

Conducting a protective sweep without a warrant is permissible when there is a reasonable belief of a threat to officer safety. This legal principle allows law enforcement to swiftly search areas where a person might be hiding and pose an immediate danger, particularly after an arrest has been made or during a lawful entry, such as responding to a call for service where the potential for violence exists.

The rationale behind permitting protective sweeps is rooted in the necessity to ensure that officers are safe from potential harm, as they cannot know the layout of the premises or whether an accomplice may be present. This balance between individual rights and officer safety is crucial in policing practices.

In contrast, scenarios involving occupant consent may permit a search or sweep, but they are based on different legal standards that require explicit permission rather than a protective sweep framework. Likewise, a disturbance call could potentially allow officers to enter, yet it doesn't inherently justify a protective sweep unless specific indications of danger are present. Lastly, routine patrols lack the immediacy or evidence of a threat that would justify a protective sweep based on safety concerns.
