A criminologist on cutting gun violence

With the reams of commentary on America's unique-in-the-world gun violence flying about, a criminologist from the University of Missouri-St. Louis, Richard Rosenfeld, points to two uncomplicated measures -- which surely could be put into effect right away.

* Increase police patrols where gun violence is concentrated, an approach that has been proven to work.

* Cut the number of deaths caused by mass shooters by blocking the availability of high-powered guns and extended ammunition clips.

As the new year gets started, maybe the likes of NRA honcho Wayne LaPierre will do something like going on a world cruise. Then we might actually see some sanity and logic win in DC.
