What Atrios says:

[T]orture is wrong. We shouldn't torture. There should be no procedures in place for torture. Everyone should understand this. But if the Joker does in fact have a nuclear bomb ready to go off underneath Gotham, and vigilante crime fighter Batman needs to employ a little force to learn the magic code needed to stop it before the timer counts down to zero, then I imagine that if Batman does in fact manage to stop the destruction of the city that no jury would convict or that a presidential pardon would likely take care of things if they did.
