The Negative Effects of Torture on the Public

Matt Welch: It's really messed up because my mind goes through. What would I be willing to do to prevent some massive attack on a train, right? Or on some other public transportation or something like that or another 9-11? But this isn't a situation where you would know you would stop that. You would have to have investigations that lead to suspects that then get targeted in the first place. "It's a very profound ethical dilemma," he says.
