How can you be suspicious of an author if you haven't read the book? I'm baffled by people that discuss the case with a fixed, or firm opinion when they haven't read much of anything about the case except what is published in US media and propaganda blogs. It's bewildering. I would compare it to a classroom where everyone is given an assignment to come to class prepared to discuss a particular topic, and where everyone decides that they can take a stance and "wing it". Obviously the discussion would be pretty low quality, or filled with confused opinions.
I would like to point out that words such as "pro-conviction" and "pro-guilt" are all about Amanda, not about the case. That is exactly what the Knox public relations team wants ... to make this all about Amanda. This isn't about two Italian prosecutors, and it isn't about a judicial system that differs from that in the United States. This is about a British woman that was murdered in Italy. If one looks at this murder from that starting point, forgetting that Amanda is American, even pretending that the victim is American for the purpose of obtaining objectivity, conclusions may be very different.
