Yep. Right or wrong, the time to argue your point is decidedly not with a heavily armed man at the side of the road.
There are always ways to rectify situations. Treating situations with police officers as a professional contact (which it is, be respectful but not deferential) and not immediately escalating (unless there's no other choice) makes taking care of any problems a whole lot easier.
That's why the police are afraid of people availing themselves of the Right to Keep and Bear arms.
