“What in particular would you be searching for, sir?”
If the officer doesn’t have an answer for that, then any warrant he might want to present would not qualify as a 4th Amendment warrant.
Naturally, when that officer explodes and yells at you to get out of the vehicle, you’d better not hesitate, and you’d better cooperate with the detention and arrest 100%. Only follow that path if you intend to sue for damages, and are prepared to go through hell to do so.
Other than that, BOHICA, so smile and give up your Right to not be searched unreasonably with a serf’s attitude.
Nonsense. We do not live in a police state. Governments pay out millions for the unlawful actions of dirty cops like you suggest.
