Photos from Haj Ali
According to an account on the Alive in Baghdad blog, the photographs were obtained through Haj Ali. Haj Ali is better known as the hooded guy from Abu Ghraib. He's since gone on to found The Association of the Victims of American Occupation Prisons.
As regular readers of my blog know, the "new" Iraqi government has been habitually abducting, torturing, and killing detainees on a regular basis. Haj Ali presents these photographs as evidence of these abuses, which are being committed by govt run militias and police forces like the Interior Ministry's Wolf Brigade.
