The atheist government of the USSR required priests to fully disclose the content of all confessions as a matter of national state security... It destroyed the Confessional of the Church in Russia - Nobody went to Confession... Ever...
To place the matter in secular terms, if every person is required to report suspected or actual crimes under penalty of Law, and is, for example, exempted from accountability for sharing his or her suspicions, the floodgates of accusations as a matter of 'expressing' one's anger with someone over anything, would be opened and we would have to open a whole new department of policing that does nothing but 'investigate' such matters... Divorces frequently contain charges of child abuse almost never prosecuted nor investigated... They are understood as punitive on the part of the litigants...
One priest was conducting 'sleepovers' with teens from his Church and took pictures of them, and it came to the attention of the Bishop... He came to a Parish Council meeting, confronted the priest, who confessed on the spot in front of all, was laicized immediately, given 2 hours to clear out his office, the evening to put his affairs in order, and told to report to the police in the morning and confess all he had done, and plead guilty to whatever charges they drew up against him, and submit to the court's sentence...
And he did so... Unto the Salvation of his soul...
Sadly, this seems to be the exception, rather than the rule...
Placing Ekklesiastical Authority under secular authority is problematic...
Ekklesiastical abuse of authority is itself problematic...
The issues are thorny...
