From the BBC:
A reservist, Darrel Vandeveld was called up as a military lawyer after 9/11 and served in Iraq, Bosnia and Africa.
In 2007, he became a prosecutor for the military commissions which tried terrorist suspects held at Guantanamo Bay, a role he took enthusiastically.
“I went down there on a mission and my mission was to convict as many of these detainees as possible and put them in prison for as long as I possibly could,” he told the BBC.
“I had zero doubts. I was a true believer.”
But his zeal did not last long.
When he arrived, he says he found the prosecutor’s office in chaos, with boxes scattered around the floor, files disorganised, evidence scattered in different places and no clear chain of command.
And more seriously, he soon discovered that defence lawyers were not receiving information which could help clear their clients, including evidence that suspects had been “mistreated” in order to secure confessions.
