What!!? the media is saying he is a hero? That is so fucked. This kid has clear mental instabilities, no normal person just gets up and shoots his sister and mom repetitively in the head, then calls 911 and acts so calm it was erie. Why the fuck was there a gun in the house not locked up? No mater the age of your kids or even if you live alone. Lock up your guns. You never know what may happen if the wrong person gets their hands on a weapon, whether the injuries are accidental or intentional.
Maybe schools should start doing mental health screenings, just like they screen you for back problems. The sign probably was when he dropped out, but thats just my thought.
