On paper, shuanggui is a process of internal discipline and regulation within the Party; in practice it's a vast, brutal, extra-legal interrogative system into which people disappear, without recourse, for weeks or months at a time. The term, which means "double designation," refers to the government notice that informs Party members to appear for questioning at a "designated time and a designated place." But the earliest that officials are aware of their misfortune is typically when the CCDI interrogators arrive at their home or office to seize their mobile phones and disappear them into a shadow world.Chinese legal scholars have privately compared shuanggui to the CIA's use of extraordinary rendition, in which a terror suspect is kidnapped and covertly interrogated outside of legal bounds. The CCDI's toolbox is similar. Officials under investigation are whisked away to isolated hotels, appropriated government buildings, or other secret locations.
Interrogators who forced feces and urine into suspects' mouths referred to the mixture as 'Eight Treasures Porridge,' a popular Chinese breakfast.
Chinese justice has been obsessed with the primacy of confession since imperial times — an ideology only reinforced by Maoism and its 'self-criticism' sessions.
