LITTLE ROCK, Ark. (KNWA) — Mass shootings have occurred more and more frequently over recent years, and the FBI has a specific definition for what qualifies as a mass shooting.
“We take our definition from the Investigative Assistance for Violent Crimes Act, which is a federal statute, and it defines a mass shooting as three or more people killed in a public place,” said Ryan Kennedy, Supervisory Special Agent and Public Affairs specialist for the FBI’s Little Rock office.
The Investigative Assistance for Violent Crimes Act was written in 2012 and became law on Jan. 14, 2013.
The FBI commonly refers to mass shootings as active shooter incidents, which is defined as “one or more individuals actively engaged in killing or attempting to kill people in a populated area.” Mass killings, three or more people killed, occur within active shooter incidents.
The FBI does not factor the shooter’s death into the number of casualties in an active shooter situation.
There were 27 active shooter incidents in 2018. The shootings occurred across 16 states and 85 people were killed (excluding the shooters) and 128 people were wounded, FBI’s 2018 Active Shooter Incidents in the United States report.
