How does an arrest differ from an investigative detention?

• A. An arrest seizes a person based on probable cause; an investigative detention is temporary and based on reasonable suspicion, not custody or probable cause for arrest.
• B. An arrest requires consent; detention requires probable cause.
• C. An arrest is only in public places; detention only in private.
• D. An arrest is always longer than a detention.

Answer: (C)

Key idea: whether someone is in custody and what justifies detaining them distinguishes an arrest from a temporary investigative detention. An arrest means taking a person into custody based on probable cause to believe they committed a crime; once arrested, the person is not free to leave and the process is formal, often involving rights advisement and possible charging or warrants. An investigative detention, by contrast, is a brief, temporary stop grounded in reasonable suspicion that the person is involved in criminal activity; it is not a full arrest, does not require probable cause, and the person should be allowed to continue on their way if the suspicions aren’t supported. Location isn’t the defining factor—arrests can occur in private or public spaces, and detentions can happen in public. The difference centers on custody status and the level of justification: probable cause for an arrest versus reasonable suspicion for a temporary stop.
