Col. Don Christensen, the chief prosecutor of the United States Air Force, sat in economy class on a flight to Venice and studied the folder of the sexual-assault case that would ultimately end his career. It was August 2012, and he was en route to Aviano Air Base to try a court-martial. Looking over the case, he could see why the judge advocate general, or JAG, at the base had requested him. Christensen had prosecuted more sexual-assault courts-martial than any other lawyer in the Air Force, and this case called for someone with experience. There would most likely be generals testifying. The accused himself was a senior officer. Even Christensen had seldom handled cases involving men of high rank. There was a simple reason for this: Victims were reluctant to report such officers, who enjoyed their own set of rules in the military justice system.
