Part II -- So what, then?
What shall we propose to ACTUALLY ADDRESS this problem?
1) Promote carrying of weapons. Defense is the responsibility of the individual.
2) Eliminate "Gun-Free Zones"! Especially schools. They are a travesty and a lie. Remove them utterly.
3) Better and effective training of teachers to react to crises like this. We should make it abundantly clear that part of a teacher's sworn (Sworn? Sure, why not?) duty is to ensure the safety of their charges. As a teacher you will instruct -- AND YOU WILL PROTECT.
4) Allow teachers and school staff to be armed.
5) Armed guards at schools
6) Better/tighter security at schools
In the end though, I still feel it is only right that we keep in view the reality of such events. They are still vanishingly rare. More American kids die every single day in car accidents. They are not on the increase. This one event -- tragic though it is -- is not sufficient cause to spend billions of dollars on new programs*, alter anything substantive about how our society works, and/or to restrict the rights and freedoms of 300,000,000+ people. There are a thousand or ten thousand very bad things that happen to people every once in a while that are just too rare to worry about or to spend any extra money, time, or effort to prevent. While death is always tragic to those affected, we are far too often buffeted beyond all reason by the emotion-driven backlash that comes from putting these things in the spotlight as if they were serious risks to society as a whole.
