When Will Amanda Knox Go Free From prison In Italy?

I can't believe that Amanda Knox is still in prison over in Italy. Its so unfair. She is so obviously innocent. she has wasted 4 years of her life behind bars. the poor girl. she should never have been convicted. there is absolutely no evidence against her that ties her to the crime. it makes me think the italian justice system is no good at all. I hope she gets released from jail some time in the next year. because this is just ridiculous. if you research the case, there is no evidence to tie her to the crime. she is so inncoent.
