So wait, if I'm so drunk I don't know what's going on and I force myself on a woman I haven't raped her?
See, this law is very troublesome. I mean if they want to change the name to "You raped her if at any time before during or after the act she decides it was rape and there is no defense to her accusation" then at least we'd be being honest.
Both men and women hook up after having a few too many drinks... like a lot. Some people function pretty well way past the legal limit, even though their judgement and their ability to recall events the next morning is impaired. Both men and women wake up the next morning wondering what they've done and sometimes look over and think "oh hell no I didn't do that!" Only men typically don't call that rape and now we have a law that allows people to call it just that.
I sat in during a statement from a guy in the Navy who had been accused of rape while on a port visit. I read the victims statement (she was interviewed by a female master-at-arms). This guy was terrified, but he was also crushed and hurt. He liked this woman. He didn't think he had raped her.
Both their statements start out pretty much the same. They were out with a larger group at a bar. When they left she came with him back to his hotel room (against our ship's rules for a male and female to share a hotel room during overseas liberty). That's where she says she can't remember anything else. He says they get there and she's getting touchy and says "I'm so horny right now." According to him she initiated the sexual activity. They had sex. She wakes up early, gathers her things, goes back to the ship and files a report. She mentions how she never would have consented...because she's married.
Unfortunately, in this case the victim was punished for violating the liberty policy. He was punished for the same thing and each one of their "liberty buddies" were punished for allowing their "buddy" to violate liberty policy. But the rape charges were not pursued.
Anyway, this guy was pretty sure he didn't rape anyone. If this was a yes means yes situation then he's a rapist.
