They happened to have the perpetrator there, if they had caught the wrong guy and threatened torture, they could well have got a confession and a load of false information. Also, there are plenty of situations where you have the right guy and they still feed you bullshit, like in the example of John McCain.

The thing isn't that threatening torture occasionally works, it is that it generates false information just as readily. It is extremely unreliable and in the process it also turns you into something despicable. Nietzsche had it right when he said: Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.
