I am pleased that the gun debate continues in the United States. I am saddened that it takes the killing of children in school to reignite it from time to time, and wish it would continue without any tragic events. I think we’re making a fundamental mistake in the approach though, much like the mistake many make when talking about curing cancer. There is not one cancer, there are many cancers. An effective treatment for one type of cancer may have no effect on another. Likewise, there are many issues related to gun safety, and what might prevent injury or deaths caused by one of those issues could be quite different from what is needed to prevent harm from another. But when somebody proposes something that might help one cause, it is dismissed because it won’t help all causes, so we end up talking past each other. I think recognizing that is an important step forward.
