It was a battle of behemoths: The Marine Corps and The Associated Press, the world’s biggest news agency, got into a tiff recently. They sparred over an AP story quoting a report written within the Department of Defense that argued that hundreds of Marines had been killed or wounded because the Corps had “refused an urgent request in 2005 from battlefield commanders” for Mine Resistant Ambush Protected (MRAP) trucks. In the back and forth, both sides employed a bit of spin, but central questions remained unanswered.
