My apologies then. I've seen too many claiming that their gun rights supersede private property rights, particularly on this current topic.
This is entirely a business decision by Walmart. It's not that they want to lose anyone's business, it's that El Paso is going to be very expensive for them, such that the risk of lost business from this decision is far less than the risk of another El Paso.
Nobody wants to see innocent folks killed, and I think Walmart is perfectly within their right to ask those who carry to keep it concealed. Only nuts who insist on opening carrying get bent over this kind of reasonable request. I could tell this guy was nuts when I heard about him claiming how Walmart was lucky to have him there, armed, and ready to defend their secured gun counter. He probably stands outside by the kiddie rides making sure no kids are dropping slugs in the bucking bronco.
As you said, Walmart made the right decision for their business model. Again, even if I didn't agree with their decision it's their stores to do with as they will. I enjoy Walmart's sporting good section, but that's not the store's mainstay by a long shot. Walmart is where I go when I need toilet paper and a pint of ice cream (then I cruise sporting goods, particularly the knife case and fishing poles, to see if anything cool is on clearance.)
I personally only carry, always concealed, maybe 10-20% of the time I leave the house. Never on the way to work because I have no place secure enough to leave the gun while working. And not every time I go out even on my days off. And I carry knowing full well that I will likely never, ever need it, that nobody should ever know I've got it, and that it's a huge responsibility to keep the gun safe and out of the hands of someone who would misuse it.
But if I ever need it, I'll be glad I have it. Just like playing the lottery is pretty much a waste of money, but I have personally met (back when I was a newspaper photographer) several people who have won $1M or more doing so.
And I will admit there is a bit of a psychological issue when it comes to guns. I know how to handle a gun safely. I've trained to do so. I understand the difference between fantasy and the real pain of others. I have the ability to empathize and understand that my irresponsible actions very well could hurt another individual, which is wrong. And I know I am a moral person who doesn't want to hurt anyone.
But, just like a chainsaw, I know that my safety precautions and safe handling of my potentially dangerous tools vastly mitigates the chance I will ever hurt myself or anyone else with them by accident. And I believe I am firm enough of character that I won't let a gun turn me into a murder, as are most people.
And I like guns. They aren't just a tool to keep me safe, not by a long shot (pun intended.) I use them for hunting, various shooting sports and plinking, with self-defense as a very tertiary reason for owning them.
But here is the rub: While I dislike people telling me that I am too stupid to own a gun safely, there are a small but substantial number of gun owners who's actions have proven that they absolutely are too stupid to have one. How do we keep our gun rights when way too many people don't seem to understand the responsibility that comes with them?
