About a year ago, a study estimated the number of Iraqi casualties since the war began at 100,000 dead—higher than any other estimate. The study was mostly ignored. Alex Blumberg revisits that study to look at the reality behind it. In Act One he reports that not only is the study probably accurate, but it says that most of the deaths were caused by coalition forces (despite concerted efforts to avoid civilian casualties). In Act Two, we hear U.S. forces trying to cope in the aftermath of some of those deaths.
