Mass shootings are a daily occurrence in the United States–literally. Gun apologists insist that if only more people had guns, then gun deaths would be less common. (The United States has the highest gun ownership rate in the world.) “The only thing that can stop is a bad guy with a gun is a good guy with a gun,” they argue. But, is this realistic?

In the recent Las Vegas shooting, Stephen Paddock shot concert-goers at the Route 91 Harvest festival. There were 22,000 people in attendance. What percentage of people should have been carrying a firearm?

In the United States, 22% of people own a firearm. If that percentage of concert-goers had brought a weapon, that would’ve meant 4,840 people were armed. What about 10%? That would mean that 2,200 people. Even only 1% means that 220 people would be packing heat. That doesn’t exactly make me feel any safer about going to concert, especially ones with alcohol present.
