If you are relying on the government to protect our young, by passing tougher gun laws and installing a few metal detectors, you are preparing yourself to become a victim. The only law that one can totally rely on is the law of self-preservation. If I were a student, I would bring my own lunch or go off-campus. In the event that one of these tragedies began to unfold, I would take matters into my own hands to protect myself and the children of the parents for whom I work. I would feel better knowing that I have a fighting chance to save lives than to spend my last moments in horror.
Evil people do evil things, and good people have every right to fight for their survival.
