Torture

These two documentaries explore violence by prison guards. The first one is one of the episodes from a series on torture, by the BBC. It explores the violence and torturous acts done by prison guards in American prisons, including Arizona and California. They also examine a possible link in a culture of violence by guards which may have made the torture at the U.S.'s Guantanamo Bay military prison possible. It is called "Torture - America's Brutal Prisons" (2005 - 50 minutes).(more info)

The second one is an episode of a series titled "Discovering Psychology". The episode is titled "Power Of The Situation"(25 minutes). In this video, psychology researches do experiments with UC Berkeley students, in which they create a mock prison and assign some of the students as prison guards, and some as prisoners. They document a phenomena in which normally pacifist nonviolent students act out in violent sadistic ways on the mock student prisoners. (more info)
