The document discusses and provides examples of torture techniques used by the US on detainees in the War on Terror, including at Abu Ghraib prison, Guantanamo Bay, and secret CIA black sites. These techniques include stress positions, sleep deprivation, waterboarding, and prolonged exposure to extreme temperatures and loud music. The document argues that these techniques constitute torture as defined by both US and international law, and that torture is an ineffective and counterproductive interrogation method that spreads human rights abuses and recruitment for adversaries.
