Where did I say it was illegal? Oh that's right, I didn't. What I said was you in body armor walking into a Walmarks with your AR in the ready position is cause for alarm and that's because it is. It doesn't matter whether it's legal or not. It is cause for alarm because it's way out of the ordinary. Prudence dictates one have situational awareness at all times and be prepared to take evasive and extreme self defense measures should the need arise. Included in that is threat recognition and assessment.
