MY TORTURE GUIDE
In respones to the torture debates, a lot of people want those opposed to torture to provide a specific list of what techniques are allowable.
Here's my stab:
If the criminal law on torture plays any role whatsoever in your determination of whether to use a particular tactic, then you shouldn't use it.
So, if you're about to commit an act, and need to consult the torture law to see if it's covered, you shouldn't do it.
If you really think you're in a "ticking time bomb" situation, but would be deterred by the possibility of of criminal punishment for committing torture, then you're not really in a "ticking time bomb" situration, and shouldn't commit the act. If the torture were really necessary to save the worlds, the prospect of criminal prosecution would be the least concern.
