Experts Doubt Drop In Violence In Iraq

Military Statistics Called Into Question

By Karen DeYoung, Washington Post Staff Writer

The U.S. military's claim that violence has decreased sharply in Iraq in recent months has come under scrutiny from many experts within and outside the government, who contend that some of the underlying statistics are questionable and selectively ignore negative trends.

Reductions in violence form the centerpiece of the Bush administration's claim that its war strategy is working. In congressional testimony Monday, Army Gen. David H. Petraeus, the top U.S. commander in Iraq, is expected to cite a 75 percent decrease in sectarian attacks. According to senior U.S. military officials in Baghdad, overall attacks in Iraq were down to 960 a week in August, compared with 1,700 a week in June, and civilian casualties had fallen 17 percent between December 2006 and last month. Unofficial Iraqi figures show a similar decrease.

Others who have looked at the full range of U.S. government statistics on violence, however, accuse the military of cherry-picking positive indicators and caution that the numbers -- most of which are classified -- are often confusing and contradictory. "Let's just say that there are several different sources within the administration on violence, and those sources do not agree," Comptroller General David Walker told Congress on Tuesday in releasing a new Government Accountability Office report on Iraq.

Senior U.S. officers in Baghdad disputed the accuracy and conclusions of the largely negative GAO report, which they said had adopted a flawed counting methodology used by the CIA and the Defense Intelligence Agency. Many of those conclusions were also reflected in last month's pessimistic National Intelligence Estimate on Iraq.

The intelligence community has its own problems with military calculations. Intelligence analysts computing aggregate levels of violence against civilians for the NIE puzzled over how the military designated attacks as combat, sectarian or criminal, according to one senior intelligence official in Washington. "If a bullet went through the back of the head, it's sectarian," the official said. "If it went through the front, it's criminal."

"Depending on which numbers you pick," he said, "you get a different outcome." Analysts found "trend lines . . . going in different directions" compared with previous years, when numbers in different categories varied widely but trended in the same direction. "It began to look like spaghetti."
