Personally, I believe that she was not guilty of the murder. She could be a horrible person and all of that but that does not necessary make her a murderer. Either way, Italy really messed up the investigation. The gathering of evidence was messy and the police did not do a good enough job linking her to the murder. There was no solid evidence linking Amanda Knox to the crime. For that reason, I have to believe that she is not guilty.
The sad thing is that this turned into a media circus and the Italian tabloids had a field day painting her out to be, basically, the devil. If this story was not so sensationalized then we might have gotten a clearer answer into what exactly happened. instead, Italy wanted to find Amanda guilty then search for evidence proving themselves right instead of looking at the evidence first.
