So? Winters relates what the accuser says.
Mackey was able to pry out of Winters that this girl had at least two sexual encounters and maybe three within a 72 hour period, wore dirty underwear with non-Kobe semen in them to her rape examination, and that Winters had not asked her, until the SECOND interview (after she had time to be prepped) why she didn't say no, or if she did, in fact, say no.
Yes, there's sordid stuff here, but the accuser may or may not have wanted it.
Remember, the judge said, after the prosecution laid out its evidence for the prelim, that its case was extremely weak.
