From The Washington Post:

Thus do right-wing extremists exploit America’s lax gun laws for political gain. Of course, the open carrying of rifles or handguns is a recipe for intimidation and potentially deadly confusion, even when not politically motivated. If shots ring out on a street full of armed pedestrians, how are the police supposed to identify the culprit?

On the whole, though, no state worthy of the name can permit exceptions to its monopoly on legitimate deployment of armed force like those in Michigan or North Carolina. Surely no sensible interpretation of the Second Amendment right to keep and bear arms would say a state must tolerate them.
