Christopher Hitchens and his wife Carol Blue, photographed by Annie Leibovitz in 1990
" In May 2008, Hitchens voluntarily experienced waterboarding, a controversial torture that has been used on prisoners held by the United States at Guantanamo Bay.
After he rejected the notion that waterboarding constituted torture, he was asked by Vanity Fair to experience it for himself. After the experience he fully changed his opinion. He concluded "if waterboarding does not constitute torture, then there is no such thing as torture."
