Study finds mass shooters have distinct patterns of buying guns

The increase in gun violence in the United States has put pressure on law enforcement and others to find ways to reduce it. In 2022, there were 647 mass shootings, up from 383 in 2016. There has also been a three-fold increase in active shooter events between 2000 and 2016. These are defined as "one or more individuals actively engaged in killing or attempting to kill people in a populated area."
