"It is just as bad to prevent the investigation and prosecution of a war crime as its commission." -- Jonathan Turley, professor of law at George Washington University Law School, on the Rachel Maddow show.
"If a truth commission investigates, it would be the shortest investigation in history. There's no question there's a war crime," says Turley.
"The easiest thing to do is to get out of the way...To say maybe your guilty, maybe not, but it's not for me to decide it's for a special prosecutor."
