The Catholic Church has issued a warning to its clergy in Washington state: Any priest who complies with a new law requiring the reporting of child abuse confessions to authorities will be excommunicated.

There’s a Christian duty to follow laws that are just as well. From a very Christian perspective, the right thing to do would be convincing them to confess outright at least.
I’m no priest and I was definitely never catholic, but that’s how I see it as someone who grew up in a protestant house.
I can tell you that that’s also what I got. The way confessions work, the priest gives you… “penance” is what it might be called? What you need to do to repent for your sins and be absolved of them. Usually that’s some prayer, but they can tell you that you have to turn yourself in and admit to your crimes to the police.
I have no idea if priests actually do that, and I imagine with the secrecy it’d be hard to get any information.
