If you are too drunk to consent it is rape.
I'll bet this is an issue every weekend at every college in America. Drunk girl sleeps with drunk guy. Hung over girl regrets her decision in the morning. In 99.9% of the cases she simply makes the walk of shame back to her dorm room. But 0.1% of the time she blames the guy and accuses him of rape. Was it rape? I dunno. Maybe yes, maybe no. It would depend on the facts. It would be a tough call if she was drunk and seemingly gave consent, but then later it turned out she was too drunk to remember what happened. (Was she too drunk to give consent?)
I'm not saying this is what happened. But I suspect this scene plays out quite often on every college campus in the land.
It does.
The vast majority of them are never charged. It requires the guy to say something really stupid. Like I don't know what happened or I was black out myself or sleep walking. If the accuser then says she remembers refusing you are DOA.
Rape kits are always done. However those are very misleading, as normal intercourse always leads to some vaginal tearing according to the Scandinavian sexual research institute.
Rape kits are only really useful when the offender is unknown or a denial that the sex happened.
Usually most paper thin sexual assaults just lead to a good once over questioning of the alleged perp and filed under not enough to charge.
Absent bruising significant tearing etc.
However I have worked in Iowa City in this area and yes, this happens numerous times every weekend.
The vast majority like 99.9% are never reported and not an actual offense. Boyfriend girlfriend two people out on a date, usually never reported or charged.
Where you see this reported is some guy finding a woman passed out at a party usually a total stranger or someone who has tried to get with them prior that they have turned down.
Edit: Read some of Elfs comments <face-palm> liked Moirannes response and others.
False rape allegations generally do not happen and if they do they usually dissolve quickly claiming rape is still taboo in our society and the victims are put through a lot of scrutiny and embarrassment.
