“One goes to jail because there were witnesses to her inability to consent, and there was medical evidence to prove the case against the aggressor.”
Medical evidence that they’d had sex. Nothing to say one way or the other that she had or had not consented (or even initiated) sex at the beginning. Was she drugged? Did he physically carry her out to where they were observed?
This is why I don’t go to drunken parties. I don’t want to wake up next to some bimbo who’s hysterical that I don’t look like Brad Pitt when she sobers up.
It might not change your mind about her consenting or not, but I’m hard pressed to believe that many young women, sluts or not, want to have sex on the ground behind a dumpster, amongst the pine cones and pine needles, out in the open so that anyone walking close enough by can see their private parts exposed. There may be a few weirdos who would consent to that, but not many. The debris on her body and in her hair are part of the evidence collected, along with her torn to shreds panties.
Good for you for not going to drunken parties, though. You’re ahead of the curve with that decision.
