No guns used in this, the most deadly school mass murder in our nations history.   You hear nothing about it, and our society learned nothing.    School killings are not new, we just don’t fix it!    Teachers with no experience of protecting the public, students in particular, are trained to teach, not protect; certainly not with a weapon.   If it takes a gun to stop someone from killing with a gun, and I believe it does, I want someone with experience in defense.   Hire a Vet!  Put him/her in a security uniform and let them do what they were trained to do.
