I have a CCH permit in NC. I work at a "helpless victims only" workplace (i.e. university campus) so I don't cc on my way to/from work. I know NC permit holders must inform LEO when approached/addressed. But if I am NOT cc'ing and am stopped in my vehicle, is it a good idea to go ahead and inform LEO I am a valid permit holder but am NOT armed? My understanding is the LEO will probably know I have a CCH permit before he approaches me after he runs my license plate. So to tell or not to tell when not cc'ing??
