What I would say is I would be willing to take the risk involved to my countrymen of not torturing suspects yes because I believe the honour and lack of precedent and state power is not worth it.
However if it really were a 24-like situation and the attacks were to be very big, then I might be able to turn a blind eye. But that is far from the case in the vast majority of situations.
I find it interesting you know say torture instead of just waterboarding. Are you willing to use even harsher methods to stop even a conventional terrorist attack?
