One of the widespread practices of solitary confinement—particularly since 2001 in the “war on terror”—is the use of hoods to control prisoners and detainees. Detainees have not (yet) been charged with a crime and, unlike prisoners of war (POWs), are not protected by the Geneva Conventions. As a result, detainees have been subjected to cruel and abusive practices. This includes hooding and “enhanced interrogation” (stress positions, sleep deprivation, extremes of heat and cold, forced nudity, forced feeding, waterboarding, etc.) In this chapter I will focus on hoods as a form of solitary confinement and how concerns have been raised about torture.
