Possibly – they must have probable cause or at least reasonable suspicion.

You do not communicate with them other than saying the following one liners…

• I do not answer questions.
• What crime have I committed?
• I reserve the right to remain silent, and everything you (cop) do will be used against you with a tort suit, civil claim for damages for Trespass.
• Without prejudice, under duress (cops armed holdup), i do not accept nor consent to contract, either implied or stated, with all non commonwealth corporate employees whatsoever, and waive all benefits on offer.

Everything they ask, DO NOT SAY NO however…  you conditionally co-operate under duress, all rights reserved, ask for the same information from them so you know who to litigate for trespass.
