It's not in a lot of states here. Don't get me wrong, you'll get harassed from time to time by cops, but there's nothing they can legally do about it. I've been arrested 3 times for carrying my AR but every time the charges have been dropped because it's not illegal. The third time I took the department to court and had the arresting officer dismissed because he was an arrogant snot while I remained calm and respectful. As long as you conduct yourself in a respectable manner they have no reason to even stop you. Even while carrying, you're still not obligated by any law to ID yourself. A citizen who knows his rights is the scariest thing to encounter for an American cop. DUI checkpoints, random stops, random ID requests, random search attempts, I deny them all. Just say the magic words, am I being detained? Don't answer any questions, if they say yes you are then say, at this point I reserve my fifth amendment right and will remain silent from here on until I speak to a lawyer. I've been in cuffs several times only to be let go because the officer chickened out with his illegal arrest. I have the utmost respect for cops, but I'll stand up to any punk who hides behind a badge.
