It is rather this editorial that misses the mark. Guns and gun-related injuries and deaths in the United States account for Vietnam-level casualties every year.
Costs necessarily accrue to society as a result of these casualties. Society must pay for police to investigate them, paramedics to try to save the lives of the victims, security guards in stores and banks, and now, after the massacre in Connecticut, armed guards in schools. This, of course, doesn't even scratch the surface of medical costs and the rehabilitation of the victims.
Just as there are costs associated with driving a car that are partially covered by gasoline taxes, so should it be for gun owners for the burden that their 2nd Amendment rights place on society. It is their responsibility, and it has nothing to do with infringement.
