That's not actually the case. Well, except in cases like this where it's a conspiracy and you've got some authorities on your side setting it up. But in real life, certainly in North America and I understand in Japan too (which is after all a society both male chauvinistic as hell and very much against people rocking the boat and making trouble) the cops and the authorities are generally unhappy with and unsympathetic to women making rape complaints and treat them like shit, while defence lawyers are allowed to drag their name through the mud and make all sorts of what would normally be considered libellous accusations and comments about them on the public record. Actually going through with a rape or sexual assault charge is a way to make your life hell.It's fast, easy to do and doesn't hurt the person who claim being molested.
