In NC if pulled over with a CC, it is required to disclose immediately to any officer that you are carrying.
The last thing you want is for a cop to find out that there's been a gun in the car and they didn't know about it from the instant they walked up to the window. As a general rule, I don't like startling people who are authorized to use deadly force.
OK, guys, thanks for the insights. I did not know the specific rules about CC permits, but you both make good sense to me.
