Salon has a heart wrenching and incredibly detailed piece of investigative journalism (something we don't see much of these days because of its high cost and uncertain payoff) regarding the 2006 deaths of Pfc. Albert Nelson and Pfc. Roger Suarez-Gonzalez in Iraq. A lengthy and violent video has surfaced from the helmet-cam of a soldier present at the encounter, where it appears that an American tank fires on American troops stationed in an abandoned home in Ramadi, Iraq:

Shot from the perspective of the soldiers taking fire from what they clearly believe is an American tank, the footage shows how Pfc. Albert Nelson and Pfc. Roger Suarez-Gonzalez died. It also records soldiers trying to save Nelson’s life, and the sound of a platoon sergeant attempting to report over a radio that the casualties were due to friendly fire. He then seems to be overruled by a superior officer who insists it was an enemy mortar attack. Troops from Nelson’s unit interviewed by Salon, including three soldiers there that day, blamed friendly fire from a U.S. tank for the deaths. “A tank shot us,” said a soldier. “That is what happened.”

An Army investigation, however, found the deaths were caused by enemy fire. Soldiers from Nelson and Suarez’s platoon, based at Fort Carson, Colo., described what they felt was pressure from above to accept this official story despite evidence to the contrary — including the video, which has circulated widely. Jean Feggins, after watching the video, said it was more evidence that the Army had misled her about the circumstances of her son’s death. The Army told Feggins that her son had died instantly, while the video shows a painfully protracted attempt to get Nelson to a field hospital before he bled to death.

The piece is well-researched and well written -- take a look. I won't post the video here -- it's much too violent and disturbing -- but if that interests you, Salon has posted it.
