7. The gun free zone is a gun nut myth...

Conservative media figures often claim that mass shootings tend to happen in so-called "gun-free zones" in order to advocate for less restrictive gun laws. In reality, most mass shootings occur where firearms are allowed, and a Mother Jones review of mass public shootings over a 30-year period concluded, "In not a single case was the killing stopped by a civilian using a gun. And in other recent (but less lethal) rampages in which armed civilians attempted to intervene, those civilians not only failed to stop the shooter but also were gravely wounded or killed."

After Orlando Shooting, The Fact-Free Firearm Fanatics Are Out In Full Force

But study after study (after study after study) has shown that where there are more guns, there is more death. I could refer to this Harvard study as evidence, but it would be insulting to the hundreds of other studies that show the same findings.

Whether it’s a country or a state or a household, a higher concentration of firearms almost always means an elevated level of gun-related deaths. If someone tells you otherwise, they’re not telling the truth.
