Vice President Dick Cheney has apparently confirmed US interrogators engage in water-boarding — an outlawed practice that creates the sensation of drowning. The admission came during an interview on a right-wing North Dakota radio program on Tuesday. Cheney said he agreed with a listener’s comment that terrorists should be dunked under water if it could save American lives. Cheney added: “that’s been a very important tool that we’ve had to be able to secure the nation.” A spokesperson denied Cheney had endorsed waterboarding and said he was referring to broad interrogation procedures. Water-boarding is barred under international treaties that prohibit torture.
