As with past FBI active shooter-related publications, this report does not encompass all gun-related
situations. Rather, it focuses on a specific type of shooting situation. The FBI defines an active shooter
as one or more individuals actively engaged in killing or attempting to kill people in a populated area.1
Implicit in this definition is the shooter’s use of one or more firearms. The active aspect of the definition
inherently implies that both law enforcement personnel and citizens have the potential to affect the
outcome of the event based upon their responses to the situation.
This report supplements two previous publications: A Study of Active Shooter Incidents in the United
States Between 2000 and 20132 and Active Shooter Incidents in the United States in 2014 and 2015.
3 The methodology articulated in the 2000-2013 study was applied to the 2016 and 2017 incidents to ensure
consistency. Excluded from this report are gang- and drug-related shootings and gun-related incidents
that appeared not to have put other people in peril (e.g., the accidental discharge of a firearm in a bar).
Analysts relied on official law enforcement investigative reports (when available), FBI holdings, and
publicly available resources when gathering data for this report.
Though limited in scope, this report was undertaken to provide clarity and data of value to federal,
state, tribal, and campus law enforcement as well as other first responders, corporations, educators,
and the general public as they seek to neutralize threats posed by active shooters and save lives
during such incidents.
