The benefit of doubt
Among the more shocking things in the Davis case was Ann Coulter's column “Cop-killer is media's latest baby seal,” in which she stated that Davis, like every other prisoner executed in the past sixty years, was “guilty as hell.” Such unshakeable confidence goes beyond a persuasion that capital punishment is a sound legal principle. Coulter asserts, in defiance of doubt, that fallible humans have never once erred in its application. She seems to imply that capital punishment works because it kills a lot of people. (And, strangely, that baby seals somehow represent objects of misplaced compassion.)
I'm reminded of Chesterton, who said “It is not bigotry to be certain we are right; but it is bigotry to be unable to imagine how we might possibly have gone wrong.” Unfortunately, bigotry in this sense is regarded by many on the right as a strength. Imagining that you might be wrong is unAmerican. Having a capacity for doubt, or even for entertaining another point of view, is weakness. It shows a heart not sufficiently whole, and a mind unforgivably muddled.
Not long before Davis died, Texan Governor Rick Perry was asked at a Republican presidential debate whether he'd ever lost sleep over the deaths of people his state has executed (over 200 on his watch). He replied "I've never struggled with that at all." It's hard to know whether this response was honest or calculated, but either way it means Perry's view of strength includes no capacity for doubt, for thinking about what he already thinks he knows. It means that for him justice is about good guys and cop killers, and a moment's hesitation - or a night's - might cost you. It means he hasn't allowed himself to think very much at all (nor, I would hazard, has Coulter) about what it means to kill a human being, especially one that might very well be innocent.
