Rest of the world: "Uh oh, there's quite a lot of guns around here. We should probably reduce those before more people get hurt."
USA: "Guns for everybody! You get a gun! And you get a gun! Everybody gets a gun! What's that? There's been a hundred shootings this week? Well... um... More guns for everybody!!"
You never cease to be a condescending asshole, eh Joe. Fewer guns =/= lower crime. Indeed our violent crime has been at a 40 year low since gun ownership began to increase.
Background checks are fine. After all, the citizen militia has to be well-regulated. I was more speaking of instances outside of this one. Armed security guards certainly would have been nice though. But in an area like inner city Chicago, where most of the gun crime of this country occurs, and where it is nearly impossible to obtain a weapon legally, people can't defend themselves from thugs and other sorts of criminals that don't care about restrictions or steal their weapons.
I want to stop gang violence AND mass shootings, and improving the readiness for GOOD people to get weapons to stop bad people seems reasonable.
