What defines reasonable suspicion?

Reasonable suspicion is defined as a standard used in law enforcement that indicates a belief that a person may be involved in criminal activity, based on specific facts and circumstances rather than mere intuition or a vague feeling. The concept of reasonable suspicion requires that law enforcement officers have a constellation of objectively discernible facts. This means that officers must rely on observable behaviors, facts, or circumstances that can be articulated.

For example, if an officer observes someone engaging in a series of suspicious behaviors—such as looking around nervously, avoiding eye contact, or frequenting areas known for criminal activity—these observations collectively contribute to forming reasonable suspicion. It bridges the gap between a mere hunch and probable cause, which requires more substantial evidence.

The other options fall short of this definition; for instance, relying solely on a hunch or a single belief without underlying evidence does not meet the standard of reasonable suspicion. Therefore, the correct answer accurately reflects the necessary criteria for establishing reasonable suspicion in a lawful manner.
