The McCain Amendment will only increase intelligence demand and create a black market in interrogation astutely predicts Wretchard:

What the McCain Amendment will do is change the bean-counting rules. It will not create a framework in which real torture can be limited and stopped. That would require accepting moral responsibility for affirming practices which may be proscribed under the Geneva Conventions but fall short of real torture. That would mean explaining to the public that we are correspondingly determined to outlaw real, barbaric torture, even when by foreswearing it, public losses must be endured. Instead politicians will want to have it both ways and promise the public that they will neither soil their hands nor let the sleeping populace come to harm. No one who desires re-election can promise the voters only “blood, sweat and tears”. The time is long since past when politicians could say to a nation at war “death and sorrow will be the companion of our journey; hardship our garment; constancy and valor our only shield.” That’s too much of a drag. Today even our conflicts, like our food, must be untouched by human hands.
