Professor Frederick Lorenz: The abuse of prisoners at Abu Ghraib part 2 of 2

The world is seeking to make sense of the abuse of prisoners by the U.S. military at the Abu Ghraib prison in Iraq. Many are looking to the Geneva Convention which addresses the rights of prisoners asserting that any acts of violence to life and person, including murder, mutilation, cruel treatment and torture are prohibited at all times. So, how did we get to this point, and why were these abuses allowed to occur? Can U.S. military personnel be found guilty of abuses when they claim that they were just following orders? And, what is the role of the Red Cross?
