Nicholas Kristof, of the New York Times, writes an intriguing column  today about novel public health efforts to help mitigate the harm of guns in our society. In his column he cites the work done by David Hemenway of the Harvard School of Public Health, who has studied just that, the public health approaches to firearms. He talks about changing societal norms that this will require. Hemenway has seen evidence that such change is possible and says, “Where I see social norms changing is dog poop. You are not allowed to let your city dog run loose now, and you have to pick up your dog poop.” He said in an interview with Kristof that if people felt as responsible to their guns as they do for their dogs, who knows if, nothing else, people might insist on safer guns or trigger locks. One can only hope!
