You forgot a very important word in law... statutory. Statutory rape. Which opens the door to a reduction of the sentences and of the meaning/severity of the act itself. Consent. But I'm away that there are more variables than that involved. I won't work on that case.
I figure after 30 years it would be more damaging to the victim herself, she will have to relive this again, in public, with the usual mediatic harassment that goes with it. The human is very resilient but unfortunately when you sneak into the depth of the selective memory, it can be a very traumatic endeavor. Justice is not always the answer.
I guess I don't understand what you mean; do you believe she consented at the time of the act?
