Seven years ago, Maj. Jason Brezler sent an urgent message to a fellow Marine in Afghanistan, warning him about an insider threat. The warning wasn't heeded, and two weeks later, three U.S. troops were dead.
What did attract attention was that Brezler had sent classified information over an insecure network. The Marine Corps then embarked on what would be a multiyear effort to kick out Brezler — claiming it was for mishandling information. Brezler maintained it was retaliation for calling attention to deaths he thought might have been prevented.
