Where does this data come from?

The K-12 SSDB aims to compile information on school shootings from publicly available sources into a single comprehensive database. It defines school shootings as situations when someone brandishes or fires a gun on school property or a bullet hits school property for any reason, regardless of the number of victims, time or day of the week, or motivation.
