Lawyers say the once-secret logs stand apart from other reports about the Iraqi security agencies because the accounts of mistreatment are recorded -- and sometimes corroborated -- by the Americans themselves.
"It's not as if, if we didn't have these documents, we wouldn't know that torture was widespread," said Matthew Pollard, who works as a legal adviser for Amnesty International, a human rights group which repeatedly warned that abuse was widespread in Iraq. "What's new is confirmation -- in their own documents -- that they didn't dispute that."
