Certainly would solve the problem. A priest should never, ever keep a secret when it involves an innocent child. Nor anyone for that matter. Disturbing. More like harboring criminals, IMO.
Priest responds: “first,people don’t identify themselves to me by name.That is by design. Second,I can’t see their faces. That,too,is by design. Third,many people...out of shame or embarrassment...disguise their voices. So even if I *wanted* to help you I couldn’t." Or say a child victim of abuse -- as in this case -- told this in confession. The priest takes the initiative and tips off the police about a possible victim:
Yeah, ring up 911 and say: "Somebody --- I don't know who--- said he or maybe she was sexually molested, but I don't know exactly what was done to him or her, or by whom, or where, or how long ago."
And that benefits whom?
Or, lastly, just put a wire and a videocam in every Confessional.
At which point, nobody goes to Confession.
That solves the problem! --- but only if your "problem" is with the very existence of the Sacraments of the Catholic Church.
