While patrolling in Iraq in 2007, former active-duty Marine Conor Curran came to question what he was doing and why he was there, when an Iraqi civilian served him tea. Curran will be one of several participants in an April 9 open discussion at the Diana Wortham Theatre — Truth to Power: A Permanent State of War (the program starts at 8 p.m.). Xpress editorial intern Forrest McDonald spoke to Curran and one of the keynote speakers, investigative journalist Gareth Porter, earlier this week. Here are a few of their remarks.
