How can we know of convent scandals when they are closed to public inspection? We must believe the accounts given by Maria Monk and others until we see otherwise.

The Catholic Answers

You cannot know of convent scandals, not because convents are closed to public inspection, but because the scandals don’t happen. That you must believe in such scandals until you see otherwise looks fairly hopeless, since you intend to keep your eyes tightly shut against any good in the Catholic Church at all.
