Friendly Fire?
According to the US Army, Pat Tillman was probably killed by friendly fire. According to an anonymous Afghani official, the firefight that killed Tillman was probably started by a land mine exploding. There were no enemy forces.
So does this make him more of a hero? Less of a hero? Neither. I think it just adds another layer of sadness to the story, knowing that Pat Tillman’s death was entirely preventable. It also means that the man who killed Pat Tillman may very well return to the US and live the rest of his life without ever knowing it.
