"...the church cannot impose mandatory reporting because some countries have repressive regimes."

It can let national bishops conferences make that decision.  Doesn't Francis want more decision making shifted from Rome to the bishops?  I can understand that "some countries have repressive regimes", have not developed criminal and civil law and an independent judiciary.  

But some have good legal systems and Pope Francis needs to recognize that and support it.  

Maybe this is one of the reasons Card. O'Malley was appointed to the CDF - to get them moving on making the changes needed to allow reporting where it is "reasonable" to do so, get rid of the requirement that a bishop has to try to "cure" a pedophile before seeking to defrock him, clean up the "legal problems" that are an impediment to trying bishops for covering-up sex abuse.  

The church is stuck in an impossible position in which children are put at risk. They don't get another 100 years to figure this out.
