Ok, except for one lucid comment by kirk that the boys fingered the girl and didn't penetrate her with their penises, I think this all goes back to the "what constitutes rape" thread a while back that discussed the Julian Assange case.
The standard for rape is simple: sexual activity without the willing consent of the person who was raped.
If you fuck your girlfriend while she's asleep, and you two didn't discuss that possibility beforehand, you raped her. If you finger a one night stand while she's still asleep and you didn't discuss it beforehand, you raped her. If you wake a girl up by slipping your morning wood into her mouth without discussing it ahead of time, you raped and you're an idiot because she might bite down.
Going back to another discussion on consent (I think about those "Slut Walks" a while back), yes, this girl could have avoided this situation. That does not make it her fault. The fault lies with the boys, period. That said, she could have avoided this. If a girl can't figure out who the creeps are, then she's too fucking naive to be let out of the house. These two boys were creeps as evidenced by their actions that night and afterwards. Does this make it her fault? Of course not. But she could have, and should have, avoided hanging out with guys like that when she was drinking. Should a woman be safe wearing a skimpy outfit and drinking in a bad part of town? Sure. All of us should be safe with hundred dollar bills sticking out of every pocket, drunk off our ass, in any neighborhood in the world. But we're not. And neither are women. All people need to be aware of their situation and take steps to protect themselves accordingly. You're not at fault if you don't and something bad happens to you, but you're for damn sure stupid. You don't deserve what happens to you, but you did something stupid and put yourself into a bad situation.
Recognition that there are assholes in the world, recognizing those assholes, and avoiding them isn't a controversial idea, unless some people choose to make it so.
Now, considering that the boys "only" fingered her, the one year sentences are reasonable. The extra year for taking the pictures is reasonable. I'm pretty disgusted that so many seem to be sympathetic to these two little shits, though. There's no room for sympathy for them. This wasn't like they were stealing bread so their starving families could survive. They treated an unconscious girl like a finger puppet and laughed about it afterward. Fuck them. They ruined their lives because they were and are assholes.
