The Senate Intelligence Committee report released this week found that the CIA tortured terror suspects by, among other things, putting hummus in a man's anus, forcing suspects to stand on broken feet, and blasting detainees with songs such as "Rawhide" at loud volumes on repeat.
Many of the interrogators' actions were shocking and cruel, but some might argue (and some have argued) that torture is a necessary tool for extracting information. This, too, is dubious. The Senate investigation revealed that the CIA learned most of the valuable intelligence it gathered during this period through other means.
Military leaders have known about the pointlessness of torture for centuries. A quote by Napoleon, which was widely shared after the report's release, reads, "The barbarous custom of having men beaten who are suspected of having important secrets to reveal must be abolished. It has always been recognized that this way of interrogating men, by putting them to torture, produces nothing worthwhile. The poor wretches say anything that comes into their mind and what they think the interrogator wishes to know." The French leader wrote that in a letter in 1798.*
Still, there will always be terrorists in the world, and we will always need to pump them for information. So if we don't torture, what should we do instead?
