San Diego County Gun Owners PAC Executive Director Michael Schwartz examined Everytown Research and Policy figures on post-Columbine school shootings and, after filtering, counted 126 incidents instead of the more than 1,100 often reported, posting the results on Gun Owners Radio. His criteria included intentional firearm discharges directed at U.S. K-12 schools or at students, staff, or others in school-related roles on campus or during school-day activities, while excluding accidents, stray fire, unrelated crimes, gang violence, personal disputes, and most off-campus events without school targeting. The group listed 126 cases since 1999 and invited verified accounts of any omitted incidents that match what the public typically means by a school shooting.
