What actions has Pope Francis taken on the issue? 
(i)The trials of priests in El Salvador accused of rape and molestation 
(ii)His role in getting victims of sexual abuse in Spain to play a key part in bringing their molesters to trial in Spain which led to a Spanish judge charging 10 priests in that case(though the case became more complicated later on) 
(iii)Setting up the tribunal in the Vatican
