There's no such this as a minor school shooting. Any incident where students are harmed is an incident too many. Sadly, school shootings have become a horrifically regular occurence. Even more sadly, this list is just a partial one. The following 21st century school shooting incidents drew the most media attention. That a full list is too long to include here is, in itself, a profoundly powerful argument for stricter gun control laws.
