In April 2021, the U.S. Department of Homeland Security (DHS) released a report about its work at George Mason University, a public research university near Fairfax City, VA.
According to the report, in August 2020 the DHS worked with about 1,000 university students, staff, and professors at the school, along with outside educational professionals, to simulate various types of school shooter incidents. The buildings selected on the campus for the two-week simulation were those that best mirrored a typical suburban public school.
