While a lot of us, me included, are inclined to want there to be some sort of repercussions for a woman who falsely accuses rape, there is one other thing to consider. A woman who knows that she may serve prison time for a false accusation is more likely to doggedly cling to the false accusation even if she starts to have second thoughts that it is the right thing to do. Without huge (legal) consequences, a woman is more likely to tell the truth when she calms down if she hasn't been truthful up to that point. I'm sure anyone falsely accused would say their first priority would just be getting those charges dropped rather than making their accuser pay, especially if the threat of a false accuser paying results in a higher liklihood of an unwarranted conviction.
Also please note that we know that she lied about the ripped shirt. As far as I have heard thus far, we don't know if it was a misguided attempt to bolster a truthful charge of rape or a misguided attempt to salvage a false charge of rape. Women have been known to lie for both reasons.
I agree with all who say there are no winners in this situation, only losers. As far as Bubu goes, he was cleared of charges so that is good enough for me.
