If it were limited to events of 50 or 60 years ago I might agree with your comments Sandthorpe, but sadly it isn't. This 'connivance' of moving PP's from one parish to another and not telling anyone about the problem in the previous parish continued well into the 90's at least, and I also remember something about the leak that Boudi mentioned.
Furthermore, even as long back as the 50's & 60's peadophilia was illegal, and the (civil) authorities should have been informed - even if the Archbishop or Vatican wasn't. They were not, and therefore it is also a cover-up.
