Which two factors justify conducting a search on a suspect?

The correct choice focuses on two critical aspects of conducting a search on a suspect: gathering evidence and self-protection.

Gathering evidence is a fundamental purpose of searches in law enforcement. When officers encounter a suspect, they must collect relevant material that may support or contradict the existing claims or suspicions about criminal activity. This evidence is crucial for building a case, whether for prosecution or clearing of suspicion.

The aspect of self-protection is equally significant. When officers engage with suspects, especially in potentially volatile situations, they need to ensure their own safety. Searching a suspect can help reveal any concealed weapons or harmful objects that could pose a danger to the officer, the suspect, or the public.

This choice encapsulates the legal and practical reasons for executing a search, enabling officers to operate within the bounds of the law while prioritizing safety and due process. Other answer choices miss the critical importance of legal justification and safety in the context of professional conduct in law enforcement.
