The places change, the numbers change, but the choice of weapon remains the same. In the United States, people who want to kill a lot of other people most often do it with guns.
Public mass shootings account for a tiny fraction of the country’s gun deaths, but they are uniquely terrifying because they occur without warning in the most mundane places. Most of the victims are chosen not for what they have done but simply for where they happen to be.
There is no universally accepted definition of a public mass shooting, and this piece defines it narrowly. It looks at the public shootings in which four or more people were killed by a lone shooter (two shooters in a few cases). It does not include shootings tied to gang disputes or robberies that went awry, and it does not include domestic shootings that took place exclusively in private homes. A broader definition would yield much higher numbers.
