A brief detention of the wrong person is permissible when the actual person sought by law enforcment is wanted in connection with a completed felony or felony arrest warrant, especially when the police diligently pursue a means of investigation likely to confirm, or dispel their suspiciouns about the detained indivudual's identity quickly. Yet, once officersdetermine that a suspect is not the individual wanted in connection with a felony arrest warrant, there is no longer reasonable suspicion for the detention, and it must promptly end.
