"church leaders still don't understand"?? It is the pope who "shielded abusers and mistreated the abused" in Buenos Aires. The first papal action was to appoint Pell and Errazuriz to his Council of Cardinals when both had many previous years of national headlines for their aiding and abetting child sex abuse. Currently, there are at least 15 active bishops accused of complicity with abusive priests who have no fear of being disciplined http://www.bishop-accountability.org/bishops/enabling/index.html
