As the cops kept asking him to show where it said he could carry a loaded firearm I kept waiting for him to say that anything not illegal is legal so unless the cops know a statute stating it is illegal it is in fact legal.
Sounds like this stop turned into a good educational opportunity, but I remain just dumbfounded that cops can just stop and detain whomever without knowing the law they think is being violated. My job requires that I know numerous laws and regulation and violation can have severe consequences including losing my business so I understand the burden. However, I don't have qualified immunity. Heck, I don't even have a gross negligence standard like an attorney doing the same work has, but instead have the burden of simple negligence. I have appreciation of the difficulties of an LEO's job, however, I also find it frustrating that they can intrude into a citizen's life based on lower standard of ignorance of the law than that with which the state burdens the citizen.
Anyone think that if one of those cops pulled over a traffic offender 10 minutes later and that offender said, "oh, sorry, I didn't know that was the law here" that the cop would say, "Oh, well then that's ok. I didn't know the law about something earlier and stole 30 minutes of a man's life from him because of it. Happens all the time. Have a good night."
