I think some investigation into the cause of the disorder would be in order here. Iraqis are not, in the normal course of things, even with no cops around, liable to turn into muggers or people who tear up the infrastructure of their cities to sell for scrap. First, there are severe shortages of necessities and a majority with no job or income whatsoever. (Try four months of 60 percent unemployment in New York or LA.) If these things were fixed, a lot of the problems would go away. Second, there is an encouragement of lawlessness by the occupation forces--both perpetration of lawlessness by them (shooting people) and suppression of the Iraqi police who seem to be the only people in the country _without_ weapons. At the time of the initial looting of Baghdad, one human shield said busses of men from Kuwait were brought in to loot, under U.S. military protection.
As one Iraqi oil ministry worker pointed out early on, the U.S. could have done this as a coup, in which everyone reports to work the next day and things pretty much continue--no civil liberties of course, but a society able to start to rebuild and recover. They didn't do that. Since the looting in the last days of the war, it's seemed likely that this was not incompetence or poor p lanning but part of a conscious project to destroy Iraq as a viable society, and the quote from the unnamed West Coast professor that Seth Ackerman posted earlier hints that this is not so farfetched.
