I don’t have anything to add to the story of the lunatic who opened fire on a freshman science class, but here’s a place you can talk about it without the taint of piety that’s getting introduced into all the news stories right now.
The killers who have been executing these school shootings are all mentally ill, sick people. I suspect that the reason schools have been targets is that they are full of optimistic young people who are exercising their opportunity to learn and preparing for a productive place in society … and the hateful, petty pissants who believe guns and violence are the answer resent that. Let’s not see any more proposals that violence in reply is the answer, it isn’t — it’s an echo of the same problem.
