Good review of the happenings. Nothing I could say that you haven't already thought of, probably, so I'll leave it with also congratulating you for standing up for yourself. "Interviewing" techniques employed by LEO's are interesting, aren't they? Trying to get you to admit to a crime by gentle suggestion - weak sauce. They sure get flustered when you assert your rights and don't fall into the traps they are taught to lay at POST and subsequent trainings, don't they?
As for the Wind[er]bag running for re-election to the senate, there's a write-in candidate from the other party who just announced his candidacy. He only needs 50 votes to be considered a true write-in candidate, and I think, if he views the 2A (and Idaho's equivalent constitutional and statutory provisions) correctly, you should write him in, if anything to send a message to the incumbent that you don't take government intrusion lightly.
Good on ya for your perfectly legal OC in a "sensitive area," and for not letting them get the better of you! I can assure you that there were many bunched panties throughout the capitol mall once word that an OC'er was in the building and nobody could do anything about it because you were perfectly legal, pleasant and nonthreatening. We need more like you.
