A police officer throws three young men into the back of a truck. Their hands are tied tightly behind them, their eyes blindfolded and they're shaking with fear. "We swear we are innocent!" cries one, terrified to learn he's been accused of terrorism. "They were playing with their mobile phones and carrying pictures of Saddam", explains the police officer. Fakhr and Razghan Remezan understand the men's fear better then most. They were recently released from Abu Ghraib after being detained on similar terrorism charges. "We had to sign a false declaration. We had to confess to being terrorists to be freed", complains Fakhr. He shows us his signed confession, admitting to having attacked Iraqi and US troops. "They call it a Happy Pass - a reward for terrorism. If you don't sign it, you don't go home." Innocent or not, these men were deeply angered by their experience in jail. And - like other detainees - they've left prison with the knowledge of how to act on their frustrations. As Razghan reveals: "In the prisons, the clerics teach you how to attack Americans."
