Okay, lets use a hypothetical and see if you have the intellectual balls (or honesty) to answer it:
You have a guy who knows where the dirty bomb is and when it is set to go off. Your wife, children, parents, friends, neighbors, loved ones, hundreds possibly thousands of others, are all at risk and there may be no time to evacuate and where do you go? What area is safe?
What do you do? Given the risk, do you care WHAT is done to that guy to get him to talk? Do you really object to a basically humane, non lethal, non injurious, non painful method used to terrify him so that he will?
Do you really consider that torture? A procedure that many in our own military voluntarily subject themselves to as part of their survival training?
And if you do, how does that not trivialize the very real torture that has been used by evil people on humanity over the millenia?
It's all in the definition.
