Can I ask what charges were brought against him, and which ones stood up and which charges were unsuccessful?
It seems to me clear that he didn't know (or more likely didn't care) what consent was, but I do indeed find it disturbing that the court didn't know.
Yes, it is indeed disturbing that the court, knowing a 14yo was grabbed in her own home and forced to endure some strange man's tongue in her mouth and entire body groped before being able to get him off with the help of two friends, would look at this whole thing and go, "wow, you should pay for that mailbox. AND say you're sorry to her mother for damaging it."
I have no idea the technical charges, I was too young to interpret those words as necessary. But it was essentially sexual assault, assault of a minor and destruction of property. Destruction of property stuck. He had to pay for the repairs and apologize to my parents for disturbing them. The assault charges were dropped on the grounds that since I knew him, it couldn't be rape. He was "just a good kid who got drunk and did something stupid."
I am _all_for_ descriptions that make this kind of result impossible to accept.
From your description, it's clear to me you were sexually assaulted. But I still don't think different consent laws would have changed your assaulter's behaviour, he obviously did not care about consent, affirmative or otherwise.
