Vargo confirmed the existence of secret Camp 7, and confirmed that he was responsible for the security at all the other camps, but not camp 7. Vargo was interviewed in February 2008, about attempts to treat captives more humanely, and to offer classes to provide intellectual stimulation. He defended the new humane efforts on the grounds that captives distracted by classes would be less likely to attack the guards under his command. Vargo was interviewed about the use of extreme force in the force-feeding of hunger striker Ahmed Zaid Salim Zuhair.
