I also live in the wild west~ Nevada. It's a right-to-carry state. I also live in a rural area where everyone has fences, gates, guns, horses and dogs. In fact it's just as likely that there will be someone will be coming down the road on horseback or on an ATV as in a car...
A couple of things bother me about this report, though. First of all, OVERKILL. Couldn't he have shot them in the leg? He was not being threatened with bodily harm.
And, what if the criminals had been local juvenile delinquents rather than immigrants?
A little more protest, I think.
