"an inmate died while shackled to a restraining chair for 16 hours. The inmate, who suffered from schizophrenia, was kept naked the whole time."
A vicious prison-gang culture plus a media world driven by sensation and horror, transplanted into a distant war in conditions of impunity...it seems simple enough. I think much of the current British migrant-basher hysteria has a similar source in the combination of unchallenged scare propaganda and a government obsessed with trying to get ahead of its press opponents - it just provides the validation.
I suppose this also supplies some of the answers to our situation. The US authorities have already said that the Abu Ghraibh torturers will be tried publicly in Baghdad. This makes sense. Robin Cook's suggestion of demolishing it does too. From a British point of view, though, this is already losing out. The government is currently refusing to publish the Red Cross report on detention in the British zone, whilst protesting that they did not know about the report - this demonstrates Alan Watkins' view that scandals in Britain always concern whether or not someone had the right to say what they did, not the facts, and also demonstrates that the government is still obsessed with trying to show mythical "toughness" in the belief that the Murdoch press will love them again. They will not, and the cruelty increasingly evident in the government's every idea (demanding that doctors refuse treatment to failed asylum-seekers..)will only increase this way.
Note - The London News Review is of a similar view about the torturers - apparently Graner had a record of stalking his ex-wife with guns and setting up secret video cameras...
