Krauthammer does a good job today as he places the problem in the context of the Church's responsibility to the broader civil society in which it exists.
How the church treats sin is not a concern for non-Catholics. Of absolute concern for non-Catholics, however, is how the church treats crime -- whether it reports criminality occurring within its gates for adjudication and punishment by secular authorities. That is the test. It is a test not of faith but of citizenship
He starts off with an excellent story, too.
I have to disagree with Krauthammer, however, when he says that the reason for the failure to report these crimes has more to do with the Church's sense of isolation, of being a kingdom-unto-itself, than it does with fear of exposure. I think it was 99% the latter, and the other one percent was the clerics' determination not to see fellow clerics in jail.
