Journalist Sabrina Rubin Erdely fired off an email to Rolling Stone editors in the middle of the night with a sobering subject line: “Our worst nightmare.” She wrote that she no longer trusted “Jackie,” the central figure in her article about a gang rape at the University of Virginia and that she believed the magazine should issue a retraction. As an attorney representing a university administrator who is suing Rolling Stone over the piece read the email aloud in court Thursday, Erdely broke down. “Are those your words?” attorney Libby Locke asked.
