Last week a U.S. Marine was removed from the front lines for shooting a "mostly dead" terrorist. You couldn't miss it because it was splashed all over the front page of every newspaper in America. But here's something you might have missed.

The US military says Marines in Fallujah have shot and killed an insurgent who engaged them as he was faking being dead, a week after footage of a marine killing an apparently unarmed and wounded Iraqi caused a stir in the region.

"Marines from the 1st Marine Division shot and killed an insurgent who while faking dead opened fire on the marines who were conducting a security and clearing patrol through the streets," a military statement said.
