There's different types of torture.
One type of torture is where millions people of people and their children and families are exposed to radiation, glass in windows that moves with the speed of bullets, and fires hot enough to melt steel. The other type is where a person thinks they're drowning, but they're not... If it's the ticking time bomb, and it's a million being tortured or one being tortured, it's got to be the one.
That said, this should never be done by sergeants on the night shift - or random CIA agents. Top generals need to be present and it's got to be rare beyond words.
