Two years later, the Army wants to get to the bottom of Pat Tillman's death:

A criminal investigation into the death of Cpl. Pat Tillman has been opened nearly two years after the former NFL player was killed by friendly fire in Afghanistan, an Army official told NBC News on Saturday.

Multiple government investigations found that Tillman, 27, was shot to death by fellow U.S. soldiers during a firefight in Afghanistan on April 22, 2004. The Army initially told Tillman’s family that he had been killed by enemy fire and portrayed the former Arizona Cardinals player as a war hero.

Col. Joseph Curtin, an Army spokesman, said the Defense Department office of inspector general had reviewed the matter at the Army’s request and concluded that a criminal probe was warranted.

This is where military expertise might come in handy. Are all deaths as a result of friendly-fire subject to criminal probes?
