I’m thinking the shooter’s probably another crazy Satanist. Perhaps he had some connection with somebody at the school (I notice he shot the psychiatrist) and perhaps not.
Either allow parents like me to carry while on property, for teachers to carry, or lock the doors - all of them - and have a check-in procedure outside of the school.
It could also have been someone who was pushed over the edge by a wife who wanted a divorce, social-services, and a court system that was taking his children away from him.
I’m not saying that this justifies anything and obviously he had issues and should have been monitored and probably separated from his children if he had any, but
Let’s hold off until we know the facts.
The system we have is enough to make most normal men close to crazy as they work hard, do the right thing and have their families torn apart by wives who divorce because they just aren’t “happy” and are supported by courts and social-services that almost to a one take the woman’s side.
