Safety is now Americans’ overriding concern. Several years ago, as I sat in a secondary school board meeting, the visiting headmaster of a K-8 school was asked what he considered the highest priority for parents in choosing high schools. I was astounded when he said “safety” rather than, for example, “quality of education.” But that was just a hint of how Americans’ safety fears would blossom in the years to come. We have become the most anxious of nations, fearing terrorists, gun rampage, sexual assault, hurricanes, tornadoes, snowstorms, identity theft, discrimination, and germs, among other things, and not necessarily in that order.
