Several years ago, Tim Ballard, who had served as a U.S. government agent for a dozen years, went rogue — but in a good way. While working as a special agent for the Department of Homeland Security, Ballard, a devout Mormon, infiltrated child-trafficking rings by posing as a pedophile. But he grew frustrated by the red tape. So, in 2013, Ballard left the department and started Operation Underground Railroad, or OUR, a private organization that conducts so-called “extraction operations” to free child sex slaves and bring their captors to justice.
