The media focuses on them. And the number has ticked up a bit. But all things considered, guns being used to murder people in school is very rare compared to all the other kinds of gun violence, especially considering suicide.I wouldn’t mind treating schools like federal buildings like courts and assume people want to get in and do harm. That doesn’t mean arm all the federal employees it means having measures to keep harm out as much as possible. Sure there are crazies that will even draw a gun in a room full of cops.
Edit : i say this because schools seem to get more threats than anything I ever hear of.
More often what I see is a local small news item about how a kid brought a gun to school and was then arrested and presumably taken to juvenile court.
