If reason played any part in the American love affair with guns, things would have been different a long time ago and we would not have so many mass shootings like the one that took the lives of seventeen high school students in Parkland, Florida on February 14. Almost everywhere else in the world, if you proposed that virtually any adult not convicted of a felony should be allowed to carry a loaded pistol—openly or concealed—into a bar, a restaurant, or classroom, people would send you off for a psychiatric examination. Yet many states allow this, and in Iowa, a loaded firearm can be carried in public by someone who’s completely blind. Suggest, in response to the latest mass shooting, that still more of us should be armed, and people in most other countries would ask you what you’re smoking. Yet this is the NRA’s answer to the massacres in Orlando, Las Vegas, Newtown, and elsewhere, and after the Parkland killing spree, President Trump suggested arming teachers.
