Col. David Hogg, commander of the 2nd Brigade of the 4th Infantry Division, said tougher methods are being used to gather the intelligence. On Wednesday night, he said, his troops picked up the wife and daughter of an Iraqi lieutenant general. They left a note: "If you want your family released, turn yourself in." Such tactics are justified, he said, because, "It's an intelligence operation with detainees, and these people have info." They would have been released in due course, he added later.
