"Police officers acting in their official role do not have rights; they have enumerated powers. Authority to compel you to tell them the nature of your business is not one of those enumerated powers. The authority to threaten a citizen with jail time for being insufficiently servile is not one of those enumerated powers."
Succinct and sparklingly clear. Any argument opposed to the young man's actions needs to speak to the above. Note: Why is this person (still marginally of an age that is between 13-19) dismissed as a "teenager"? This is a YOUNG MAN who probably works to have a car, pays taxes, can sign contracts, vote, and so on. His "rights" are only very, very slightly different than most of the readers here.
