Rule 2.2 - Authority to Request Cooperation(a) A law enforcement officer may request any person to furnish information or otherwise cooperate in the investigation or prevention of crime. The officer may request the person to respond to questions, to appear at a police station, or to comply with any other reasonable request.(b) In making a request pursuant to this rule, no law enforcement officer shall indicate that a person is legally obligated to furnish information or to otherwise cooperate if no such legal obligation exists. Compliance with the request for information or other cooperation hereunder shall not be regarded as involuntary or coerced solely on the ground that such a request was made by a law enforcement officer.
