When evaluating shooting incidents to determine if they met the FBI’s active shooter definition, researchers
considered for inclusion:
■ Shootings in public places
■ Shootings occurring at more than one location
■ Shootings where the shooter’s actions were not the result of another criminal act
■ Shootings resulting in a mass killing
■ Shootings indicating apparent spontaneity by the shooter
■ Shootings where the shooter appeared to methodically search for potential victims
■ Shootings that appeared focused on injury to people, not buildings or objects

This report does not encompass all gun-related shootings. Because the risk to civilians in active shooter
incidents appears related to the apparent randomness of so many victims, a gun-related incident was excluded
if research established it was the result of:
■ Self-defense
■ Gang violence
■ Drug violence
■ Contained residential or domestic disputes
■ Controlled barricade/hostage situations
■ Crossfire as a byproduct of another ongoing criminal act
■ An action that appeared not to have put other people in peril (for example, the accidental discharge of a
firearm in a bar or a suicide in a public parking lot)

This methodology was first articulated in A Study of Active Shooter Incidents in the United States Between
2000 and 2013.5

It was applied to 2019 shooting incidents to ensure consistency.

Citizen Engagement and Casualties
In three incidents, unarmed citizens confronted the shooter, thereby ending the shooting.
■In one incident, a student restrained the shooter. The shooter was apprehended by campus police at the scene.17
■In one incident, a student was killed as he confronted the shooter. Two other students subdued and disarmed the shooter. The shooter and his co-shooter were arrested at different scenes on the school campus.18
■In one incident, a doctor was wounded as he wrestled the gun from the shooter; another doctor and a patient restrained the shooter until law enforcement arrived.19

...Citizens bravely and selflessly confronted the shooter in three incidents. Three citizens (two doctors and a patient) saved medical center colleagues and patients. Two students in two separate incidents lost their lives to save their classmates. One security officer saved fellow congregants.

However, if you'd like to include every little possible thing to inflate the numbers to achieve a predetermined conclusion, go for it. Would you also like to include shootings that were within half a mile of a school that did not involve any of the students from that school as school shootings?

The agreed-upon definition of active shooter by US government agencies (including the White House, US Department of Justice, FBI, US Department of Education, US Department of Homeland Security, and Federal Emergency Management Agency) is “an individual actively engaged in killing or attempting to kill people in a confined and populated area.” In most cases, active shooters use firearms and there is no pattern or method to their selection of victims.
