SANTIAGO, Chile (AP) — Pope Francis accused victims of Chile’s most notorious pedophile of slander Thursday, an astonishing end to a visit meant to help heal the wounds of a sex abuse scandal that has cost the Catholic Church its credibility in the country. Francis said that until he sees proof that Bishop Juan Barros was complicit in covering up the sex crimes of the Rev. Fernando Karadimas, such accusations against Barros are “all calumny.”
