So I went to see what had been said, and I didn't even get past the third post before I had a question. Mkemse said "Waterboarding is a form of torture that consists of immobilizing a person on their back with the head inclined downward (the Trendelenburg position), and pouring water over the face and into the breathing passages.[1] Through forced suffocation and inhalation of water, the subject experiences the process of drowning and is made to believe that death is imminent." If a person was not slanted in such a way, would the person drown? Is that the reason for the slanting, so that it would be more torturous than murderous?
