Which of the following best describes the term "reasonable suspicion"?

The term "reasonable suspicion" is best described as knowledge suggesting potential criminal activity. This standard is used in law enforcement to justify brief stops and detentions when an officer has specific and articulable facts that lead them to suspect that criminal activity may be occurring. It is more than a mere hunch, as it requires some factual basis or evidence that an officer can articulate. This differentiates it from other concepts such as a belief formed after a more thorough investigation or having definitive proof of guilt. Reasonable suspicion allows officers to act upon their instincts based on observed behavior or circumstantial evidence, thus enabling proactive policing while still respecting individuals' rights.
