Wow, thank you Mal.
I couldn't believe what the police did (or didn't do). I'd have punched them, not that it would have made the situation any better! God. I am sorry.
Your story reminds me of my incident in New Orleans in spring break 2004. I mentioned it in the "Stupidest things you've ever done" thread... and I still don't think it was a rape, even though a stranger picked me up on Bourbon Street when I was shitfaced/blacked-out drunk and we ended up having sex at his hostel (and losing my virginity, which I never, never, NEVER would have done if I was sober)... because when I sobered up, I had vague recollections of really getting into the sex with this person, and for all he knew (he was also drunk), enjoying it thoroughly. There was no evidence to prove that it wasn't consensual, for all this guy knew, and my own brief memory serves that correctly. We e-mailed back and forth after this event and established the facts, and he ended up being a fairly decent person despite the circumstances... he had no idea that I was a virgin (since I gave no indication at the time), and apologized profusely. Lord knows ANYthing could have happened to me when I was blacked out on Bourbon Street, so I took this event as providence.
All I can say is, do not drink (or overdrink) in situations where you don't trust the people you are with (I was with a couple of idiot frat/sorority people I'd met the day before, who needed a ride South from our university), and where you doubt your ability to keep your head about you. I've never been a huge drinker except for a few months during that year, but I will never drink much again, certainly not to the point of blacking out.
