The only times I might be able to look the other way on torture is if it is with the following conditions in mind:

1. A strong indication that there is an imminent attack.
2. Time is a factor.
3. Said person is likely to have information that could prevent the attack.
4. The methods are designed to obtain information and not simply to live out some revenge fantasy.
5. The person, administration, agency, whoever, that is authorizing it is prepared to accept responsibility.

At this point, it would feel more like an expansion of self-defense. Reasonable fear of imminent bodily harm to yourself or another, use of force only so far as reasonably calculated to prevent the harm, accepting responsibility for the consequences of your actions.
