A long and thorough debunking of the controversial study was just published in National Journal.

Published by The Lancet, a venerable British medical journal, the study [PDF] used previously accepted methods for calculating death rates to estimate the number of "excess" Iraqi deaths after the 2003 invasion at 426,369 to 793,663; the study said the most likely figure was near the middle of that range: 654,965. Almost 92 percent of the dead, the study asserted, were killed by bullets, bombs, or U.S. air strikes. This stunning toll was more than 10 times the number of deaths estimated by the Iraqi or U.S. governments, or by any human-rights group.
