This sounds bogus to me too, sort of like the charges against the wikileaks weirdo. However, the Algore crazed sex-poodle incident didn’t ring true either but then there was that sudden divorce from Tipper...
This was actually made public a long time ago. She didn’t file charges at the time, however, because she was just starting out as a journalist and he had that all-important thing, power.
I think maybe she’s getting disgusted by seeing a bunch of massively well-paid defense attorneys here in the US basically getting him off by destroying the victim in the press. That’s what they do, and that’s what they’re hired to do, and if you have as much money as he does, you can get some really evil ones.
Christine Banon probably realizes that this is what would have happened to her if she had made the charges at the time, and maybe she’s just the tiniest bit angry that he has apparently made a world-wide career of acting like a “chimp in heat.”
