To be fair, the overwhelmingly vast majority of schools still do not have anyone shot or stabbed. But yes, I agree we are going wrong somewhere. When we had a serial killer epidemic in this country, you saw changes in the way law enforcement worked, and extensive research done into the mental state of the killers. Now that we have a mass shooting epidemic, it would be best if we responded similarly, with targeted research and resources devoted to mental health. But people keep talking about guns instead.
