Which encounter type requires only reasonable suspicion of a crime?

• A. Investigative detention
• B. Formal arrest
• C. Consensual encounter
• D. None; all require probable cause

Answer: (A)

Understanding the levels of police-civilian encounters helps explain why only reasonable suspicion is needed for this type. Not every encounter is a seizure or arrest; some are voluntary and require no suspicion at all. A consensual encounter is allowed when the person agrees to talk or interact with the officer, and the person is free to leave at any time. No suspicion is required to start this kind of contact, and there’s no restraint on movement. When police want to briefly detain someone to investigate further, that is an investigative detention. This is the Terry stop: it rests on reasonable suspicion that the person is involved in criminal activity. It’s a short, limited detention, and the officer may conduct a very limited frisk for weapons if there’s reasonable suspicion that the person is armed and dangerous. Formal arrest, by contrast, requires probable cause to believe the person has committed a crime. That’s a higher standard than reasonable suspicion. So, the encounter that requires only reasonable suspicion is the investigative detention.
