I’d never heard the following argument against “tough” interrogation techniques: 80% of our police force is comprised of ex-military folks. If we encourage (or allow!) these soldiers to “do what it takes” to get the job done, they will import that when they return home. I’m not sure this is outcome-determinative, but it’s nice to hear the moral slope argument. Someone who starts down a slippery slope will continue on that slope. We should consider the categorical nature of our actions and consider a choice in any direction to be an imperative. we’ve heard all this before. I just hadn’t heard it as related to the interrogation question!
