Two years ago, a Johns Hopkins University study published in The Lancet estimated the number of civilian casualties in Iraq. It came up with a number—100,000 dead—that was higher than any other estimate at the time and was mostly ignored.
Captain Ryan Gist was given a particularly tough assignment in Iraq: To build relationships with a town where U.S. bombs had killed twelve innocent people. But first he has to apologize to the families of those who were killed.
The Lancet's new study of deaths in Iraq, by the same research team that did the earlier study, yielded an astounding number—650,000 civilian deaths. Producer Alex Blumberg talks to Ira about the debate over this new study.
