The U.S. military has done almost nothing but lie about the death of Pat Tillman in Afghanistan, and it's difficult to believe that new investigations will give his parents the knowledge, and maybe the peace, they deserve. This story in the New York Times, a followup to work done in other media -- the Washington Post and LA Times in particular (but, sorry to say, not the San Jose Mercury News, which is being beaten again and again on a story that it should own) -- is a litany of government venality and parental stubbornness. Will they ever learn the truth?
