Not saying rape is okay. It clearly is not. But what the hell is a 14 year old doing at a party, and why the hell did she get black out drunk? We can talk peer pressure, but no one made her get drunk (unless we're talking roofie drunk).
Back in college, I can remember false calls of rape happening a lot. Girls get drunk, sleep with someone they wouldn't normally sleep with, then cry rape the day after. Happened to a mate of mine. Nearly ruined his life as well. Then the girls story unraveled and she admitted finally that it was consensual.
Anyways, clearly a 14 year old shouldn't be out partying and drinking and getting drunk. You're just asking for trouble. Strong parenting.
