Kim Roberts is setting herself up for obstruction of justice charges. Then again, she's already done that. Dumb as a box of rocks. But she clearly knows more than one way to turn a few bucks.
I am not so sure, the police and prosecutor knew early on that no rape happened and talked to people like Kim as little as possible. I doubt they ever asked her about the car ride. They were trying to keep plausable deniablity and not collect too much evidence, since they knew it was likely to support the truth.
She is talking to the press. She is not under oath. What obstruction of justice?
