text: "Exceptions can be made for repressive regimes if necessary."
  
  Yes, and half the world, at least demographically, falls under that category -- repressive regimes. But, as you say, that challenging demographic should not prevent the pope from doing away with the Pontifical Secret, if only to protect children in countries governed by non-repressive governments/regimes. One wishes the pope would likewise hold bishops equally accountable, liable, responsible -- have them tried in some kind of tribunal -- as priests currently are. Some bishops are/were notorious offenders. 
  
  Real  episcopal responsibility consists in sharing, acknowledging the mistakes and crimes of one's own appointed clergy, especially if the bishop's responsibility is identical with his honesty. Priests, after all, are not self-appointed. The episcopacy's job is to "oversee," "look upon," (from Gr. "episkopein"). Needless to say, the whole issue of episcopal accountability needs to be addressed and dealt with.
