This is truly horrifying. Those poor kids. My heart goes out to them and their families.

All the arguments about guns don't kill people, people do and what about knives are simply wrong, because nothing can kill people as fast as a person armed with guns. How many could he have killed with a knife before he would've been stopped?

Gun control and stricter background checks might prevent these crimes in far away future, but already too many guns have been sold to public anyway. Plus, if someone can bring themselves to go and kill kids, they probably are messed up enough to wait a couple of days to get the guns. There's not going to be an easy and effective solution for this problem.
