I think Athenslawyer is correct in his apparent belief that it is difficult to suppress a statement to individuals who are not law enforcement officers. But, I also believe (without fully researching this topic) that it is sometimes possible if the person is a student and he is forced to speak under threat of expulsion. Difficult suppression issue, but, again, circumstances are key.
