traffic stops, conduct....
I'd suggest checking
www.handgunlaw.us or buying a 2012 copy of the Gun Law Guide;
www.gunlawguide.com . Atty David Wong markets a legal guide to gun & knife laws for travel in the USA/related areas(PR, DC, etc).
I'm not an active sworn LE officer or hold a JD but in general, for traffic stops, I'd stay calm, be polite and follow the state/local laws re; concealed carry, firearms.
If I were in a LE contact or stop, I'd hand my DL, vehicle reg, insurance card-ID and my valid CC/W license. If the trooper or officer asked me if I had any weapons or ammunition in the vehicle, I'd be honest.
Many sworn LE agencies train LEOs to be alert or key in on any movements or watch out for weapons.
Dont twitch or act jumpy when you are in a stop. I'd also be ready to provide any documents/IDs quickly. This speeds things up and avoids any hassles.
As a MP for four years, I can honestly tell you that some drivers act properly in traffic stops and some wig out over every little thing.
Keep in mind that sworn LE officers are mainly concerned about their safety. They may not know you, your background or your concealed license status. They aren't out to "get" you or frame you on a personal level.
I've had many traffic stops over the years and can only think of 2 incidents with uniformed LE where I felt they were unprofessional or could have handled the stop better.
In closing, know & understand the local-state laws, be calm and you'll be okay.
