Mass shooting statistics in the United States - Washington Post
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.
