An excerpt:
One would think that if widespread gun ownership had the robust deterrent effects that gun advocates claim it has, our country would be freer of crime than other developed societies. But it’s not. When most citizens are armed, as they were in the Wild West, crime doesn’t cease. Instead, criminals work to be better armed, more efficient in their use of guns (“quicker on the draw”), and readier to use them. When this happens, those who get guns may be safer than they would be without them, but those without them become progressively more vulnerable.
