"Reasonable suspicion" is defined as a belief based on specific and articulable facts that a person may be engaged in criminal activity. This standard is used primarily in law enforcement when officers need to justify stopping and briefly detaining an individual for investigative purposes. It is more than just a vague hunch; it necessitates that an officer can point to particular facts or circumstances that would lead a reasonable person to suspect a crime is taking place.

For instance, if an officer observes unusual behavior, such as someone loitering in a high-crime area or attempting to conceal their identity, these specific observations can contribute to reasonable suspicion. This concept is a critical part of Fourth Amendment protections against unreasonable searches and seizures, as it requires a certain threshold of justification before an officer can take action, distinguishing it from mere intuition or unfounded assumptions.

Understanding this definition helps clarify the balance between individual rights and law enforcement duties, reinforcing the necessity for officers to act on informed beliefs rather than baseless assumptions.
