If you found out he had attempted to rape a 15 year old girl?

Yes, I am referring to the Kavanaugh case.

But really. Lets say you are a parent of a 17 year old boy. You find out thru sources he did it, you confront him. He becomes angry at first but then breaks down sobbing that he did it and he is now really, really, sorry.

What are your options? I can only think of the following:

1. Turn him into the police which will mean a trial and him possibly serving time plus being required to register as a sex offender.
2. Talking things over with the girls parents and working out some sort of resolution where he agrees to apologize and never speak of this again.
3. Nothing. Besides smacking the boy around and vowing to never letting him out of your sight again and hoping this goes away.
4. Moving.
5. Sending him away to go to say a boarding school or to live with another relative.

I'd probably attempt 2, and if that got nowhere, I'd maybe try to get him out of the country. If I even got a hint that 2 might not work, I'd probably try to get him out of the country. I know it's not the right thing, but it's hard to get past those parental instincts.

I'm really opposed to sex offender registries -- they seem like additional post-sentence punishment. Plus, why single out sex offenders? I'd also like to know if a murderer or burglar moved into my neighborhood. The existence of these registries would help me (wrongly) justify to myself that I'm doing the right thing by getting him out of the situation by any means necessary.
