Watch this footage from the White House spokesperson and I'm sure you'll understand exactly what torture means...
(i.e. exactly what they want it to mean.)
In other words, the Bush administration defines torture in a way similar to the way that Clinton defined the word "sex", as in "I did not have sex with that woman."
The only honest thing she said was "I'm not saying that reasonable people could not look at (our definition of torture) and disagree..."
Obviously, the White House's definition of torture was crafted by unreasonable people.
