To the Journal editor:
The violence in schools needs to be reduced. Nothing involving human interaction can be completely stopped. But the decision on what to do and how to do it rests with you.
It's symptomatic of a dysfunctional government and/or culture to see more violence in schools, not less.
Schools, shopping malls, post offices, large office buildings, movie theaters, etc. are chosen, for the most part, because they represent a captive audience for the killer. More dead bodies. The intelligence (if any) of the killer doesn't go beyond this.
1) The principal (and assistant principals, if any) needs to be armed with a concealed revolver. Shooting classes are to be attended. As most schools are in a weapons-free zone, go concealed anyway, but tell no one of your decision. Jobs and guns are replaceable, seven-year-old children are not.
2) For every 100 students at a school there needs to be one school staff member who is armed. This will provide between six and 15 armed teachers to confront the killer before any damage (hopefully) occurs. In addition to knowing how to use a concealed firearm, one must be willing to use the weapon whenever called upon. If you are too fearful of protecting children in your care, then don't bother.
3) This is one of those rare occasions (outside of the combat soldier, the police, etc.) in which it pays to get extremely angry, and to vent that anger against the criminal while the children are still alive, not afterward.
4) Stop being a fearful adult throughout your lifetime, and instead become a courageous citizen. This isn't easy for most, but it can be done.
5) Study the philosophy of Ralph Waldo Emerson and Thomas Reid. Their beliefs are of value within these circumstances.
As stated before, the decision rests with you, whether a parent or a school employee.
