Christopher Hitchens underwent waterboarding for a Vanity Fair story. His conclusion?
I apply the Abraham Lincoln test for moral casuistry: "If slavery is not wrong, nothing is wrong." Well, then, if waterboarding does not constitute torture, then there is no such thing as torture.
Below is an excerpt from his day in the life of a torture victim:
In this pregnant darkness, head downward, I waited for a while until I abruptly felt a slow cascade of water going up my nose. Determined to resist if only for the honor of my navy ancestors who had so often been in peril on the sea, I held my breath for a while and then had to exhale and—as you might expect—inhale in turn. The inhalation brought the damp cloths tight against my nostrils, as if a huge, wet paw had been suddenly and annihilatingly clamped over my face. Unable to determine whether I was breathing in or out, and flooded more with sheer panic than with mere water, I triggered the pre-arranged signal and felt the unbelievable relief of being pulled upright and having the soaking and stifling layers pulled off me. I find I don't want to tell you how little time I lasted.
