...make it this one, by Malcolm Nance, a longtime counter-terrorism agent:

The carnival-like he-said, she-said of the legality of Enhanced Interrogation Techniques has become a form of doublespeak worthy of Catch-22. Having been subjected to them all, I know these techniques, if in fact they are actually being used, are not dangerous when applied in training for short periods. However, when performed with even moderate intensity over an extended time on an unsuspecting prisoner – it is torture, without doubt. Couple that with waterboarding and the entire medley not only “shock the conscience” as the statute forbids -it would terrify you. Most people can not stand to watch a high intensity kinetic interrogation. One has to overcome basic human decency to endure watching or causing the effects. The brutality would force you into a personal moral dilemma between humanity and hatred. It would leave you to question the meaning of what it is to be an American....

[Waterboarding] does not simulate drowning, as the lungs are actually filling with water. There is no way to simulate that. The victim is drowning. How much the victim is to drown depends on the desired result (in the form of answers to questions shouted into the victim’s face) and the obstinacy of the subject. A team doctor watches the quantity of water that is ingested and for the physiological signs which show when the drowning effect goes from painful psychological experience, to horrific suffocating punishment to the final death spiral.

Waterboarding is slow motion suffocation with enough time to contemplate the inevitability of black out and expiration –usually the person goes into hysterics on the board. For the uninitiated, it is horrifying to watch and if it goes wrong, it can lead straight to terminal hypoxia. When done right it is controlled death. Its lack of physical scarring allows the victim to recover and be threaten with its use again and again....

According to the President, this is not a torture, so future torturers in other countries now have an American legal basis to perform the acts. Every hostile intelligence agency and terrorist in the world will consider it a viable tool, which can be used with impunity. It has been turned into perfectly acceptable behavior for information finding.
