"The Case for Torture" Argument

This argument, "The Case for Torture," is simply arguing that torture is a necessary thing in times of crisis, such as when a terrorist is going to bomb a populated area, or when a preemptive strike is going to happen. He says the torture of one person to stop the slaughter of many other people is a very necessary thing that we must do. He argues his point by using the Toulman Logic; he introduces the first counter-argument, explains it, then refutes it. He then goes through other arguments in the same way, sort of like an argument in real life. Overall, he says torture is worth it because it saves the lives of many other innocent people. I do not think that he uses any fallacies; he simply uses theoretically real-life scenarios in order to bring across his point. For example, when one person says it is unconstitutional, he says it is unconstitutional of the terrorist to bomb many innocent people in a populated area. A potential counter-argument that was not brought up by the author is that it is possible that a man thought to be a terrorist is tortured, then later discovered not to be, but nothing is done to the man to compensate him after his right as a citizen has been violated.
