Hoover fellow Peter Berkowitz applauds a new book on terrorism and US civil liberties by Richard Posner, co-author of arguably the most high-minded blog on the planet:
Posner admonishes those libertarians who would brook no trade-offs in civil liberties, in exchange for heightened security measures, for missing the larger picture. Nothing, he points out, is more sure to bring about a severe restriction of civil liberties in America than the backlash following the failure to prevent another 9/11, or worse.
As for interrogation techniques, here's the key passage from Berkowitz's review. Sorry for the long quote, but it's worth reading:
Setting aside for the moment America's international law obligations under the Convention against Torture, Posner points out that the Constitution, which regulates the gathering of evidence, interrogations, trials, and punishments in criminal cases, has very little to say about the acquisition of information from terrorists for the purpose of preventing death and destruction.
The currently applicable constitutional rule is that methods of interrogation that "shock the conscience" are unlawful. But, as Posner points out, this test is sensitive to context: "What shocks the conscience depends on circumstances. In life-and-death circumstances the use of even highly coercive methods of interrogation is unlikely to shock the conscience of most people, even thoughtful and humane ones."
Yet not all highly coercive methods of interrogation rise to the level of torture, which, according to the Convention against Torture, is defined as the infliction of severe physical or mental suffering. Nevertheless, Posner is convinced that "torture is warranted to avert a greater evil." But warranted is not the same as constitutional or lawful.
Even though he believes that many consciences would not be shocked by the decision to shove knives under a person's fingernails to obtain knowledge about the location of a nuclear weapon set to explode in a few hours in Washington, Posner concludes that it would be unwise to hold that the Constitution permits torture. In cases of emergency, where torture is warranted but not constitutional, Posner the pragmatist prefers "to trust public officers to perceive and act on a moral duty that is higher than their legal duty." This approach regards torture as a form of morally and politically justified civil disobedience.
I don't enjoy saying I agree with that, but I do.
