Mother Jones report on mass shooters and how more guns will not prevent them

But through a combination of national surveys and manufacturing and sales data, we know that the increase in firearms has far outpaced population growth. In 1995 there were an estimated 200 million guns in private hands. Today, there are around 300 million—about a 50 percent jump. The US population, now over 314 million, grew by about 20 percent in that period. At this rate, there will be a gun for every man, woman, and child before the decade ends.

There is no evidence indicating that arming Americans further will help prevent mass shootings or reduce the carnage, says Dr. Stephen Hargarten, a leading expert on emergency medicine and gun violence at the Medical College of Wisconsin. To the contrary, there appears to be a relationship between the proliferation of firearms and a rise in mass shootings: By our count, there have been two per year on average since 1982. Yet 25 of the 62 cases we examined have occurred since 2006. This year alone there have already been seven mass shootings—and a record number of casualties, with more than 140 people injured and killed.

Appeals to heroism on this subject abound. So does misleading information. Gun rights die-hards frequently credit the end of a rampage in 2002 at the Appalachian School of Law in Virginia to armed "students" who intervened—while failing to disclose that those students were also current and former law enforcement officers, and that the killer, according to police investigators, was out of ammo by the time they got to him.

Hargarten of the Medical College of Wisconsin argues that mass shootings need to be scrutinized as a public health emergency so that policy makers can better focus on controlling the epidemic of violence. It would be no different than if there were an outbreak of Ebola virus, he says—we'd be assembling the nation's foremost experts to stop it.
