UPDATED: Compiling Cases where concealed handgun permit holders have stopped likely mass public shootings

This is a revised, updated version of a post originally written on April 21, 2015.

Columnist Eugene Volokh wrote in the Washington Post on April 20, 2015: “Have civilians with permitted concealed handguns stopped such mass shootings before?” We provided Volokh with a list of such cases, which he used.

Below, we have collected news stories on more cases of permit holders stopping mass public shootings with their handguns (we separately collect cases where concealed handguns are used to stop other crimes). There is no reason to believe that this list is comprehensive, given how little media coverage is devoted to these heroic acts. In addition, we make no attempt here to list here the vast number of defensive gun uses in general that are reported daily in the US.

Permit holders stopped some mass public shootings that gained extensive news coverage, but only a few stories mentioned that it was a permit holder who stopped the attack. The stories frequently get other facts wrong.

A note: Gun control advocates raise the concern that concealed handgun permit holders who stop an attack might accidentally shoot a bystander. They are also fearful that the police might accidentally kill the permit holder. While such incidents are a possibility, they have yet to occur. We probably do not have all the cases where a permit holder stopped a mass public shooting, but if a permit holder were to shoot a bystander, it seems clear that such an event would get news coverage.

[This post has been updated. Cases have only been systematically collected since 2014. Because of the lack of news stories that accompany these cases, we believe that we have found a much greater percentage of the cases since 2014 than earlier.]
