I wouldn’t normally do a follow up blog on the same topic in the same day, but the comments have forced my hand. You raise more questions than you answer. Here are two more that confuse me.
If you think that torture doesn’t work, why does interrogation work? No one doubts that plain old interrogation (torture lite) often works. Does it make sense to you that additional discomfort would make interrogation work slower or less often?
If you think there’s no moral justification for torture, would you accept the nuclear destruction of NYC (for example) to avoid torturing one known terrorist? (No fair extending my question to more ambiguous hypotheticals.)
