The cop was a moron and over reacted and is a typical example of someone with just enough knowledge of a subject to get himself in trouble. Meaning, he knows that a CHL holder must inform him when he asks for ID, but not that it only applies when the CHL holder is carrying and probably that the penalty has been removed.
I understand your eagerness to get the stop over with so you could be on your way. I may or may not have done the same thing. It would have depended on how much of a hurry I was in or how much I was ticked off at his over response. If I was really in a hurry I might consent to a search. However, if he really rubs me wrong and I'm in a fiesty mood, I would not have consented and taken a passive stand against his over reactions.
