The FBI has published a report compiling statistical data regarding 277 active shooter incidents in the U.S. between 2000 and 2018. Each of the pages in the report focuses on a particular active-shooter topic, such as casualty breakdown, shooter’s weapon, and incident locations. For example, the casualty breakdown page shows that most casualties (both wounded and killed) in active shooter incidents occurred in open spaces, a finding heavily influenced by the 2018 Las Vegas incident that resulted in a total of 547 casualties. Looking exclusively at deaths, the report notes that commercial facilities had the highest number of these (365). In the incident locations page, the report identifies businesses open to pedestrian traffic as having the most number of incidents (74), with lower but still significant numbers for businesses closed to pedestrian traffic (37) and government properties (19). The information in this report is intended for a wide variety of stakeholders, including law enforcement officers, corporations, and the general public.
