With the new information I do agree that this was rape. The boys certainly knew she wasn't enthusiastic, and she did make at least a half-hearted protest.
But honestly, all concerned acted stupidly. Any girl who cannot be firm and know to immediately extricate herself from this place shouldn't be going anywhere unsupervised.
Unfortunately the only ones who can be punished are the boys and that punishment is fairly harsh. I'm not sure I could vote to convict in a case such as this. That could depend upon the attitude of those involved while in court (for example if the boys were acting cocky and arrogant, or if she was acting virginal and outraged, I might think that the lessons which ought to have been learned by this incident haven't been learned). If they were all just a bunch of upset, seemingly sincere kids I'd probably vote no and just let them learn from what happened.
Excuse me but NO. Being in a persons car, house or bedroom doesn't "imply" yes. No...a victim is a victim and it is the rapists fault, the rapists responsibility. Going into someones bedroom at a party doesn't mean they want to have sex anymore than someone walking into your kitchen means they want to cook you an apple pie. Get it?
