Murder "works" too, but we still don't allow it

I'm not surprised to hear supreme wingnut Rush Limbaugh trying to justify the U.S.'s illegal torture of prisoners, by trying to "prove" that it works. That, of course, is completely beside the point. There have to be higher standards than the ones our "enemies" have. Otherwise, we're no different from them, and deserve no better. Maybe that's true, but I'd like to think it isn't. If we're just as evil as those who oppose us, then who's to say who should win?
