On July 9, 2019, Walmart announced they would stop selling firearms in New Mexico after a new "public safety" laws was introduced in the State expanding background checks: the company would have been forced to conduct background checks for guns it would't sell, and the management was also worried that people bringing guns into Walmarts to register them would create safety issues for associates and customers.

What neither Walmart, nor goverments and politicians worldwide seem willing to understand that madmen and mass shooters would not ask any permission or follow any law once they decide to act it out. Much less do they care about stupid "no guns allowed" signs and other rules imposed by managers and lawyers to protect themselves from any liability in case of a... well, a shooting.

If Walmart – or any other similar establishment – would just stop follow anti-gunners (or self-appointed gun control advocates at large) and would instead carefully select, hire, properly equip and train private security personnel to a good level, criminals and madmen would think twice before barging in with a loaded gun.

And this, leaving the whole "Gun-Free Zone" argument aside just for the sake of brevity.

This is the price we pay for living in a world of incompetent quacks.
