A former US soldier who worked on interrogations at Guantanamo Bay has written a damning expose of the brutal, degrading treatment he says was meted out to prisoners there. Sgt Erik Saar’s book, Inside the Wire, comes with the US military’s treatment of prisoners in the spotlight due to court hearings over the Abu Ghraib prison scandal. In an interview with the BBC, Sgt Saar says that bizarre, sexual abuses at the prison camp set dangerous precedents that paved the way for mistreatment of US detainees in Iraq.
