Podcasts Alex Gibney & Trevor Birney, Wanted in Belfast for the Documentary ‘No Stone Unturned’ Alex Gibney’s “No Stone Unturned” uses leaked police documents to investigate an unsolved mass murder in Northern Ireland. Now the police are pushing back. On August 31, police raided the Belfast homes and office of producer Trevor Birney and journalist Barry Mccaffrey and arrested them over the leaked documents. Gibney has been notified that he’s also wanted for questioning in the United Kingdom. He describes it as “an act of intimidation” against journalists doing their jobs.
