Not a big deal. I heard an interview with the alleged victim: she's cool with it.
So what? The Anglo-American system is premised on crimes being against society, not just the direct victim(s).
If you want a justice system that is purely victim driven - abused spouses can be beaten in public with no consequences so long as they don't officially complain, children can be abused with no consequences as long as they stay silent, etc. - then maybe that matters. But at the time, she was 13 and drugged, doubly incapable of consenting.
