When I fly, I feel safe. I know that every air crash has been studied extensively and problems have been identified and corrected. Each terrorist incident brings new safety measures, no liquids, shoes off, everything scanned.
When there is an extreme violation of the law, i.e., shooting people, running them down with a car, etc., I see a prosecution and punishment. This, however, does not make me feel safer. It is like taking every plane after a crash and sending it to the desert to store; we learn nothing.
Could we possibly study perpetrators and see what happened to them, learn what society needs to do to keep that “air crash” from happening again? As far as I can tell we just keep sending them off to the desert and learn nothing.
