Torture and the Ticking Time Bomb

This, from Alex Tabarrok, via Kevin Drum:

It does not follow from the "ticking time bomb" argument that torture should be legal. The problem with making torture legal is that the government will abuse its powers. I do not trust the government, any government, to use this power responsibly. Leviathan must be heavily restrained, especially when it comes to torture.

Here is where economics can make a contribution. By making torture illegal we are raising the price of torture but we are not raising the price to infinity. If the President or the head of the CIA thinks that torture is required to stop the ticking time bomb then they ought to approve it knowing full well that they face possible prosecution. Only if the price of torture is very high can we expect that it will be used only in the most absolutely urgent of circumstances.
