It’s not just kids doing the shooting. It’s to do with deteriorating mental health, poor social connectedness, availability of guns, and more media reporting.
Well the shooter drills might help. Did you know that when the j6 rioters stormed the capital buildings, the interns immediately got people to go into offices; shut, lock and barricade doors, turn off lights and hide out of sight of any windows or doors. They did this because they’d got the practice in school.
