Here are two articles from two different forensics journals which indicate that a significant amount of lying is going on about this sort of thing: http://www.ipt-forensics.com/journal/volume6/j6_2_4.htm
http://www.theforensicexaminer.com/archive/spring09/15/ Considering the amount of damage even an accusation of sex-related crimes will cause the accused, this represents a serious problem in our society. You worry about the girl who accused someone having her name in the papers. Good for you, but why aren't you worried about the boy having his name appear in the papers too? His life will be ruined no matter whether the accusation is true or not. This is probably why we hear so many accusations of sexual impropriety made about politically-involved people. These sort of accusations can be dangerous weapons, especially when those who wield it can do so anonymously.
Here is why I think it's important that the victims remain anonymous: The emotional pain that a false accusation brings is enormous, there is no doubt about it. But there is no way it could compare to actually being raped. No way. Every time that your name appears in a paper, every time it's used on television more people know what's happened to you. It's essentially like pro-longing the brutality. There is no perfect solution to this. Your points are valid, very valid. My suggestion would be that somehow if you are found to have falsely accused someone of rape then people should know about it. Your name should then be in papers, TV etcetera. -I'm sure this is unrealistic, but perhaps that would dissuade the false accusers.
