Hot off an Esquire article as well as a lawsuit positing that NBC's Chris Hansen-hosted Dateline: To Catch a Predator series went above and beyond the call of journalism in the name of exposing Louis Conradt, a former Murphy, Texas, DA who took his own life as a camera-toting policeman breached his home, ABC's own newsmagazine is getting in on the action.
