Somehow I knew this was coming, but one of the reasons US officials are saying that there has been a dramatic drop in sectarian violence in Baghdad is that they aren't counting all the people killed in car bombings.  Crazy I know, but then again if you check you'll find that they did the same thing during the last big "surge" operation in Baghdad during the Summer of 2006.  In short, we're still only counting the corpses dumped in the street and obviously killed execution style while hundreds more have been killed in car bombings.  Ah, progress.
