This time feels different. Not in that the horrific tragedy at Umpqua will result in definitive political action (it won’t). Not in that the traditional news cycle will largely forget this tragedy within a week (it will). And of course the usual bromides were trotted out by the usual suspects: The shooting was at a gun-free zone (it wasn’t), and those attract mass killers (they don’t). Our gun problem is a mental health problem (not really). Criminals don’t follow laws, so gun control won’t work (why have any laws?). None of that changed. Rather, I no longer fear that we as a country risk...
