Are we still debating whether people would torture to save the lives of their children, or to keep a nuke from taking out New York City?
Thing is, that’s not what’s happening.  We aren’t waterboarding prisoners who are about to set of a nuclear bomb in New York.  We aren’t waterboarding prisoners who have the interrogator’s daughter hostage.  We aren’t waterboarding prisoners who know where the secret anthrax bioweapons lab is, and we have only hours to stop them.
That does not happen.  Debating what you’re capable of in certain extreme situations is all well and good, but what does that have to do authorizing torture by the cops, the FBI, the CIA, and soldiers?
Yeah, all you tough guys who don’t hold with coddling terrorists are all hot to torture them.  Except you always come up with a scenario, where you KNOW the guy is a terrorist, and you KNOW he knows where the bomb is, and you KNOW that there’s no other way to find the bomb.  Except, that’s bullshit, because that never happens.
You want to know a more realistic torture scenario?  You’re on a patrol in Iraq, and you search some guy’s house, and you turn up bomb making equipment.  You take the house owner prisoner.  Now, are you gonna torture that guy?  Electrodes to the testicles, until he starts naming his buddies?  Is that the standard you want?
You claim you don’t want to see Paris Hilton tortured for drunk driving.  Except when torture becomes official policy, somehow it doesn’t remain confined only to the “worst of the worst”, because the torturers are beyond the law, and anyone who doesn’t like what they do becomes the next target.
The idea that we oppose torture because we’re concerned about being unfair to Khalid Sheik Muhammed is ludicrous.  Sure, terrorists and murderers don’t deserve a fair trial.  Except, how do you know your prisoner is a terrorist murderer?  What method do you use to determine who is a scumbag who doesn’t deserve the right to a trial, and who is an innocent person who does?  Some sort of tribunal seems in order, which reviews the evidence against the prisoner.  And the government will argue that the prisoner is a criminal who deserves to have his civil rights taken away, and I suppose we should appoint an advocate for the prisoner, to make sure any evidence that he’s innocent gets revealed.  And then an impartial third party will review the evidence and listen to the arguments on both sides.  And only after careful consideration and due process do we declare that a particular prisoner is a scumbag who doesn’t deserve a fair trial.  And those who aren’t deemed scumbags, well, I suppose we could go ahead and give them a fair trial after this tribunal, but perhaps we should skip a step and let them go free, after all, we’ve found that they didn’t do the crime they are accused of, so it would be pretty wasteful to hold a trial for a guy we already declared innocent.  How’s that sound?
