The U.S. should not be torturing people. The Geneva Convention defines something like waterboarding as torture, and in the least would call for a review of this practice. The government knows it's wrong, which is why they did it in territory outside of the Geneva Convention.
I'm not surprised at all that our government tortures people. There are probably other foreign facilities that we don't even know about where other kinds of grusome techniques are employed. I just wish our government would stop trying to act all self-righteous like it's something we would never do. Our government likely tortures people all the time in classified scenarios.
