. . . The Marines have been warned: Any rough treatment or even harsh language aimed at a detainee is forbidden. When making an arrest, they are instructed to ask their subject if he will voluntarily go with them. “We don’t want any of our Marines to make a scene,” said Capt. Yuri Paredes, commander of the battalion’s Alpha Company. “People will think we’re degrading them.” Cases of detainees resisting are few; even while protesting their innocence, most go without a struggle. For the Marines, it’s a test of their ability to follow orders and keep their anger in check. Most detainees are suspected of planting roadside bombs or taking sniper shots at troops. “It’s hard to put our feelings aside when these guys were shooting at Marines,” Staff Sgt. Jason Moore said. “But we do it; that’s what makes us better than them.”
