So what does that mean for those of us who understand the relative risks? It means that we have an uphill battle to fight against the emotional response of those who are overly concerned about this scenario, and generally facts and numbers don’t do any good. They will keep seeing themselves in that scenario and become more and more afraid.
This is why I didn't like the NRA response to put armed guards in every school. It legitimized the hysterical panic reaction by accepting the notion that there's a significant risk. Of course, it's not politically acceptable to tell the truth: yes, it's horrible what happened but freedom comes with some level of risk, but in this case the risk is very low.
