[JURIST] Videotapes show Guantanamo Bay [JURIST Hot Topic] military prison riot squads subduing some detainees by punching them, tying one to a gurney and forcing them to strip from the waist down, according to a report by investigators from the US Southern Command [official website] obtained by AP. Investigators found no signs of systemic abuse at Guantanamo, but concluded that the tapes raised questions about mistreatment of detainees. Several of the questionable clips showed riot team members punching a detainee repeatedly in a spot not normally used to subdue prisoners, kneeing a detainee in the head and repeatedly spraying a detainee with pepper spray. AP has more.
