This guy sums it up...
"The Meredith Kercher murder is one of those mirrors that reflects the prejudices of whoever is looking into it. There is no physical evidence and no credible motive, and yet an egotistical prosecutor is blaming Amanda Knox anyway. In the USA, this would only happen if she were black. Perhaps partying American college kids are so hated in Italy that Amanda will be treated as blacks are treated in the USA, and she will be convicted not because of the evidence but because of general resentment of shallow rich Americans. Personally, from what I've read I don't like Amanda Knox. She sounds spoiled, naive, and shallow. But that's not a crime. I loathe the prosecutor, who has a counterpart in every city in the USA - a preening, intellectually dishonest bully who cares more about making newspaper headlines than in serving justice. It's the same all over the world. Power and prejudice are the enemies of justice."
