Yep, March 2003 was when the Red Cross first started raising concerns about the treatment of prisoners. However, somewhere in the chain of command, the complaints were stopped in their tracks - possibly the officer who was benefitting from interrogating/torturing these "softened up" prisoners.

Actually, late last year or early this year, a soldier was reported in the papers as facing disciplinary action for abusing prisoners - she'd reportedly been kicking them repeatedly, stomping on their groins and inciting other soldiers to do the same. I'm uncertain as to the outcome of the investigation into her conduct; I don't believe it's been reported widely, if at all. Of course, with no pictures to show off, the media took very little interest.
