“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 this list is comprehensive, given how little media coverage is devoted to these heroic acts. In addition, we do not attempt here to list the vast number of defensive gun uses in general that are reported daily in the US.” – Crime Prevention Research Center, February 8, 2023
