If I might point out...
The original New York Times article this all seems to be based on shows that the problem of human rights abuses by Iraqi authorities is being addressed, and when sufficient evidence was found, perpetrators were punished.
David's "hang 'em high" opinions notwithstanding, I don't think the actual situation is something to get overly worried about at this stage. I don't think any rational person could say the human rights situation in Iraq is worse than it was three years ago.
