Last word about guns

Well, maybe not the very last, because I have confidence that the gun nuts will devise new outrages, but for a while they have provided an unanswerable argument against the concept of "responsible gun owner."

There aren't any, but even if there are, it is impossible to identify them, as proven by the Punta Gorda murder:

Officer Lee Coel, 28, was put on administrative leave Tuesday as the Florida Department of Law Enforcement investigates why real ammunition was used by mistake at an event designed to bring police and the public together in the small Gulf Coast city of Punta Gorda.

Why, I wonder, does anyone assume live ammunition was used "by mistake"?
