His name is Mark and he's from Birmingham. If you know the AL UT instructors, you know who I'm talking about. It was the March 2011 class in the Huntsville area.
He was very clear about informing LEO's if you're carrying during a routine traffic stop: he recommends not, except under the circumstances mentioned earlier. He also said that if you decide to inform, he recommended just handing them your DL with your CWP. But his final recommendation was to not inform. It seemed most in the class agreed with him.
As far as badges, you probably already know what he said about that!
