Her ex-husband, Dominique Pelicot, was found guilty of drugging and raping his then-wife – and recruiting scores of men online to abuse her while she was unconscious, over the course of a decade. Fifty other men were also found guilty, most on rape charges. What made the trial all the more remarkable is that Gisèle Pelicot waived her right to anonymity, inviting the world into the courtroom.
