For the past four years, Vokey has served as chief of all the Corps' defense lawyers in the western United States — and he's played a key role in some of the military's most sensitive legal issues, including the murder investigation in Haditha, Iraq, and in the debate about detainees at the U.S. prison camp at Guantanamo Bay.

So when Vokey announced recently that he wanted to leave the Corps, it said something troubling about the military system of justice that he's served for almost 20 years. Vokey charges that some commanders and officials in the Bush administration have abused the system of justice, and he's going to retire from the Corps May 1, 2008.
