The folks in Baghdad have to be seriesly sleep deprived. Picture a few of those blasts outside your window every night for 3 weeks.
I am guessing that the soldiers in Baghdad are so sleep deprived that they can't see straight enough to tell when the 3rd ID is coming in.
Another thing strange about those blast...there are no sirens. Usually there were a couple of sirens that you could hear off in the distance.
