My first thought when I heard about this was where were the parents? Who bought them the booze. None of these kids should have been drinking. None were old enough to buy the liquor. Why are those questions not being answered?
If there is anything to be learned from this entire debacle it should be that ultimately, you and YOU ALONE are responsible for your own safety. Do not depend on friends and acquaintances to watch your back when you are blind drunk because chances are they have been drinking right along with you and at the very least have impaired judgment. obviously the parents were not looking out for the welfare of any of these kids. What if instead of being raped she had fallen asleep?
