Survivors or no, I really don't see the point of this commission.   If you want to protect children from predators, you educate your children.  If abuse happens, you report it to the police (not your bishop).   That's the lesson of the church's sex abuse scandal:  you don't depend on a church (any church) to police itself.   

I've studied many other religions and cults, big and small, in how they deal with scandal.    When apprised of wrong-doing within their ranks, all of them react the same way:   they cover up.   It's always outside forces that provide the motive force for reform.
