Be careful not to misunderstand the hundreds of school shootings reported by various databases. Almost 90% of these incidents are AT school, not IN school, that is, on school grounds. Many occur at night, on weekends, during summer, and do not involve students. Many do not involve any injuries, and few result in student fatalities. From 2010 through 2023, 94 students were fatally shot inside K-12 schools by an assailant, and 64 of them were from the four extreme cases: Sandy Hook, Parkland, Santa Fe, and Uvalde.
