Active shooters in 2022 killed or injured more than 300 people, the most in 5 years, FBI says

Washington – Active shooters in America killed or injured 313 individuals across the country in 2022, the most casualties recorded in the last five years, according to a report released by the FBI on Wednesday.

Federal investigators define "active shooters" as "one or more individuals actively engaged in killing or attempting to kill people in a populated area." The FBI said the report is intended to assist law enforcement, first responders and the public understand current threat levels. 

Despite an 18% decrease in violent incidents involving active shooters in 2022 compared to the year prior, the number of casualties increased by nearly 29% — from 243 to 313 — the highest in the last five years.
