What this armed citizen did is admirable. He did save lives. I carry a concealed pistol from the time I get up to the time I go to bed but a man carrying openly makes me nervous. Open carry in the cities has been illegal inTexas since the 1880s. I really prefer going about my business, armed, without disturbing those around me.
Same here at first, the range I go to has a couple of RO that carry on an open holster. You would think it wouldn't be a big deal, but my years of indoctrination have convinced me other wise. After about ten seconds I got over it, if open carry was legal in Texas, people would be nervous, but after a week it'd be business as usual. The disturbance of carrying openly would be gone quickly, it would just be like living at a dove hunt 24/7.

Except no ones constantly peppering you from a couple hundred yards away.

Think of the small talk you could have with all the other law abiding open carriers!
