Probably going to be ostracized, but here goes, anyway.
Up front: I have a CHL and carry always. I know the laws covering gun control in Texas, and I check out and obey those of other states when I travel. And I am in favor of the Second Amendment. We don't love the laws that interfere, but there are some around that we have to contend with until they're changed.
Now. What is wrong with just being friendly to the officer? If he stopped you for a traffic violation, you'd show him your DL. He'd probably call in for wants & warrants on you, and if your were clear he'd probably cite you for the traffic violation or not, and let you go.
If you go to the market and write a check, they'll ask for your ID. You'd show it, and go on about your business. If you violate my space, and step on my toe even though its not really crowded, I'd normally cut you some slack and be cordial to you about it. "Don't worry about it." ... that sort of thing.
The officer has a duty to check out any citizen's complaint, no matter how asinine it is. He'd do the same for you. Why not try to understand his position?
What's wrong with: "Sure thing, Officer. I'm not a bad guy... I'm just exercising my right to carry a weapon. Here's my ID. Other than this, how's your day going, Sir?"
So what... if you don't have to according to some obscure finding in some other state? You'll more than likely be delayed a shorter amount of time if you're friendly, than if you handle the situation the way the smart aleck in the video handled things.
An unlawful stop? I don't think so. When an officer gets a MWAG call... no matter how asinine the call or caller be, he's got a "reasonable" reason to check you out.
I do understand what my "rights" are... but I also know what it's like to have to deal with a smarta$$ in the public arena, who just wants to "exercise another right"...
In most cases sugar is a lot better than vinegar. JMHO.
Be blessed,
