I've always thought of this question as a pretty tough one to justify in either direction, personally.
On one hand, using brutal torture techniques is outdated and in countries that have come as far as those in North America, torture should be the farthest thing from our mind. Who's to say where the line is if we agree it is indeed moral to torture an enemy? Where does the morality begin and end? What's too far? Is there a "too far?"
On the other hand, If you know the the person being tortured is a known terrorist, and the torture is by trained professionals, what's the problem? The good guys should be doing anything they can to get information and stop other potential terrorist plots, right?
I think there's tons of different points to argue here, so what do you think? Let me know!
