The ACLU has been aggressive in their assertion that U.S interrogation tatics violate the Geneva Convention. Here is what the ACLU says about torture:
Torture threatens our most treasured values and it is wrong:
• Torture is illegal, banned by both domestic and international law.
• Torture doesn't work. The information elicited is inaccurate; torture victims themselves tell us they have confessed to crimes they did not commit in order to end their suffering.
• Torture puts our troops at greater risk, increasing the chance that, should they fall into enemy hands, our servicemen and -women will be tortured in kind. Countries around the world have already begun citing the United States when justifying their use of cruel and unusual punishments - most recently the Junta in Myanmar.
• Torture tarnishes the image of the United States abroad. Torture degrades the rule of law and puts the core values of our democracy - the belief that all men are created equal and have the unalienable right to life, liberty, and the pursuit of happiness - at risk. It not only creates new enemies abroad, but is damaging our relationships with long-term allies.
