The Army is set to release a new report on the Abu Ghraib prison torture scandal that charges leadership failures at the highest levels of the Pentagon, Joint Chiefs of Staff and military command in Iraq contributed to an environment in which detainees were abused in Iraqi prisons. This according to a report in the New York Times. The same investigation has also found that un-muzzled military police dogs were used to frighten detained Iraqi teenagers as young as 15 at Abu Ghraib. Dog handlers reportedly told investigators the procedure was sanctioned by top military intelligence officers. Meanwhile U.S. Army Staff Sgt. Ivan Frederick is expected to plead guilty at a pretrial hearing today to one of the charges against him for abusing detainees at Abu Ghraib.
