I once got pulled by a young trooper. He told me I was in violation of the law, because I was carrying my gun on my person instead of in my glove box, despite having a carry permit. I politely explained that he was wrong, and cited the letter of the law. He insisted he was right.
I didn't argue with him any further. There is no point in arguing with a cop on the side of the road. I politely allowed him to assert what he thought was correct, and went on my way.
When I got home, I made some phone calls. Soon the state AG's phone started ringing.
When it was over and the dust settled, EVERY SINGLE trooper station in the state recieved a letter, the Attorney General's legal position paper, explaining to them that a person with a permit CAN carry on them in the car, and that the troopers were not allowed to harass them about it.
I call that a win.
