Someone should tell her to shut-up, don't say anymore in public and get a lawyer.
Given that this is a rape accusation, I am tempted to give the accused the benefit of the doubt. The primary difference between the rich and the poor in China consists of the rich having more money. The less well-off are not necessarily more ethical. There is a non-zero possibility of the victim having second thoughts after a consensual encounter. Rape accusations are a permanent black mark even if the accused is judged not guilty after a trial. It's possible that she lured the parents stateside to discuss a payoff in exchange for not filing false charges, then stiffed them after negotiations broke down over the size of the payoff. In other words, she may have wanted an exorbitant amount they weren't prepared or were unable to pay in order to prevent her from filing false rape charges. The Duke lacrosse incident isn't some kind of unique phenomenon.
While I understand the anonymity requirement for rape victims stateside, it does have the effect of reducing the adverse reputational impact on women who successfully file false rape charges. Bearing false witness carries no personal cost apart from the time involved and the rigors of courtroom interrogation. In countries where accusers are identified, very few people file rape charges unless rape has truly occurred, because once the charges are filed and their identities disclosed, the notoriety of being rape victims stays with them the rest of their lives.
