Let's make it clear for the dimmest bulbs among you: the kids at Columbine High didn't die from too many guns, they died from too few. I'm not suggesting that the teachers should have carried guns not as franchised agents of the state. They should have carried guns as ordinary individuals, exercising a sacred right, and in performance of a solemn duty to protect the young lives that were placed very foolishly, as it turned out in their hands.
The only reason that we humans and all creatures have made it thus far is because of the lessons learned consciously and unconsciously through the challenges we have been through.
