I only have this to say about the DSK case and the recent turn of events:
Here is the DA's letter to the defense, outlining the areas in which the accuser admitted she made false statements.
Nowhere in the letter does it state that the accuser retracted her allegations about the rape itself. Nowhere does it state that evidence has come to light proving that Strauss-Kahn was innocent, or that the accuser was not raped. The areas retracted by the woman relate to previous issues connected to her attempts to get into the country, remain here, and maintain her residence. The retraction related to what she did immediately after the alleged rape--wait in a hidden area of the hallway, or continue on to clean other rooms--does not really make it impossible or even unlikely that she had been raped. Yes, those retractions of statements under oath are harmful to her credibility. Credibility is crucial in a case of he-said, she-said. But there are other credibility issues, too, related to Strauss-Kahn's prior predatory behavior toward women, and there is the forensic evidence of rape relied upon by the DA after the woman was admitted to the hospital for examination.
In any case, it looks as though a man with a history of assaulting women will go free, possibly because he is innocent, or possibly because he had the juice to pull in fixers, or possibly because the truth is somewhere in the middle. One thing I know: at no point did his defense raise the issue that he had been the innocent victim of a seduction. Because even the French can't be stupid enough to believe that one.
