They'll shift to meet legislation. That may be the option for some countries, and it may even be something you guys in the States can do too. Mandated reporting, no ifs, no buts, do not pass Go, contact the Police or go directly to jail.
But the whole process and procedure of their internal judicial structure... they're still hauling people in front of judicial committees to face their abusers in spite of said abusers just being out of prison for those very offences. They need to broaden their evidence requirements. They can do this easily. Their internal letters show that they can re-write the meaning of a word when it suits their needs.
I mean really you'd expect them to introduce training around child safeguarding issues for elders, you'd expect a clear policy for how someone could report, you'd expect some basic organisational 101 stuff to be going on. But they have to accept first that they have a responsibility. That they have a duty. That saying 'but we warn parents...' is not sufficient on its own.
