When you are pulled over and your plate is run, the cop knows immediately who the car is registered to and weather they have a CCW permit or not. I have been advised by LE that should I be pulled over..when the cop comes to the window, ..have my hands at 10/2 on the wheel, palms up. Doing this shows the cop that I have been coached by another cop and it will put him at ease a bit.
I've been pulled over (3) times while carrying in Michigan, car off, hands at 10 and 2 on the wheel, and tell him first thing that I have a weapon. I never had a problem,
