Some comments are addressing the carry regulations in Texas. Many states do not require a permit, many authorize open carry, meaning wear the firearm on your hip in sight.

I carried a concealed firearm in Washington State for years in connection with training. The state required a permit and it was not open carry. A friend and I were shopping for a BBQ and he wears his off-duty weapon behind his back. He bent over the meat display and several people saw his firearm and were alarmed. They didn't see the badge on his waist. I carried mine in a shoulder holster which was comfortable but inconvenient in hot weather when I had to wear a jacket.

Carrying a firearm 24/7 prepared us to react as this patron did.

Another takeaway from this incident is the comments regarding how the left leaning prosecutor was elected.

The thief served 8 years of a 15 year sentence for murder and was out on bail on yet another charge. I believe the controversy is not the shooting itself but the need for the head shot after the suspect was down and no longer a threat.

Maybe the hero Texan wanted to insure the suspect didn't sue him.
