What is the primary purpose of a protective sweep?

The primary purpose of a protective sweep is to ensure the safety of police officers when they enter a premises, especially in situations where there is a reasonable belief that an individual may be concealed inside and pose a threat. This type of sweep is focused on the immediate safety of law enforcement personnel, allowing them to assess and secure the environment before proceeding with other investigative actions. While evidence of a crime, legal compliance, and gathering information may be secondary benefits of a protective sweep, the fundamental rationale lies in safeguarding the officers involved in the operation. By prioritizing their safety, a protective sweep allows law enforcement to manage potentially dangerous situations more effectively.
