This is an image obtained by The Associated Press which shows Sgt. Michael Smith, right, with his black dog Marco, Sgt. Santos Cardona, second right, with his tan dog Duco with a detainee and Pvt. Ivan L. Frederick II, left, at the Abu Ghraib prison in Baghdad, Iraq on Dec. 12, 2003. Cardona, an Army dog handler was part of a small crew of corrupt soldiers who enjoyed tormenting detainees at Abu Ghraib prison in Iraq, a prosecutor at his court-martial said in an opening statement Tuesday, May 23, 2006. But a defense lawyer said Cardona, who is charged with abusing prisoners at Abu Ghraib, followed the law and obeyed orders at a time when the Pentagon was demanding intelligence from Iraq through a fractured chain of command.
