Tragic and sad, but not unexpected. What kind of 18-year-old monster goes to shoot up a bunch of kids.
Kids these days are growing up in such toxic and corrosive society. It's like growing a plant in bad soil.. you get wilted and rotten plants once they reach adolescence. It's not always the adults we should be most worried about. Unfortunately as America continues to collapse these things will become more common, not less, as people more people snap. That said, I'm pretty sure 1 million children could be dead from shootings and nothing would change policy wise.
