Or are they either trying to help families and children be kept out of harm's way, while also protecting those dioceses from further criminal charges of collusion and conspiracy?
I don’t know the reasons why any individual diocese releases or chooses not to release the names. You’ll have to contact officials there for truthful answers. Anything I say would be an opinion or guess.
I haven idea if they are breaking the law. Have you studied to be a lawyer? I sure haven’t. Can’t help you with that one.
Your last question is so loaded. It implies that a diocese that waits to release names is harming children. Usually, when a priest is accused, they are removed from duties until the matter can be resolved. You do realize that most of the accusations stem from abuse that happened over 30 years ago, right? The Church has taken many steps to prevent this from happening again. You may have a problem with how the Church used to take care of these matters but they are doing an amazing job now.
