guys were not drunk and they were aware what they were doing but that doesn't necessarily mean it was a rape or imo. as the got so inebriated she couldn't even stand by her own, she was giving up everything of herself in the hands of those two guys and as a 16yr old she should've known the result of drinking so much alcohol. guys didn't force her to drink that much alcohol nor had they kidnapped her or something. was voluntary to hang out with those guys and get drunk, putting herself in a situation where she was wide exposed to guys s, so having sex with the guys was supposedly voluntary too, something the must have expected tbh. it's like you agree to sleep in the same bed with a strange man but you later sue him for raping you, it's quite obvious you've agreed to let him do everything with your body when you've agreed to sleep with him imho.
