Motherland,
On Friday, in China, a deranged man entered an elementary school and stabbed 22 children with a knife. Fortunately, last I had heard none had died. I have no doubt that had he been able to obtain a gun he would have used a gun instead of a knife. I am not suggesting guns need to be banned in the US. Such a thing is literally impossible. I was merely referencing another deranged act on the same day of similar type in a very different culture. China has, in the last few years, had a rash of adult men stabbing school kids in schools.
Deranged people do deranged things and sometimes those deranged things are violent. The question becomes, "What can we do to reduce the harm that they do?"
