It is not Mitt Romney’s fault that the apparent length of the Decent Interval between a massacre of innocent teenagers — in this case by a neo-Nazi whose cause and means have received aid and comfort from the United States government — and a return to politics as usual is less than 48 hours.

A civilized society being a place where the desire to have military-grade weaponry — unless you are in the military — is properly understood to be weird.
