You are right except for one thing: Cardinal Mahoney was no longer the archbishop when Francis took over.  He was long since retired.  Finn and Nienstadt were reining bishops. There was nothing for the pope to remove Mahoney from.  

But I also want to make clear that I am very much aware of the double standard of the left when it comes to child abuse.  They only seem to really care about child abuse when a priest does it. That does not excuse the Church's non-action on child abuse, nor the cover-ups. 

I like Finn's conservatism as much as anyone else does--but how anyone can defend his actions when it came to Shawn Ratigan I do not understand.  Why didn't Finn just go directly to the DA and let the DA worry about whether Ratigan's computer constitutes child pornography? It isn't Finn's job to determine what is and is not child pornography.  That is the job of the DA.
