To clarify, I first got interested shortly after Massei was released/translated. Amanda and Raff were in jail, and awaiting the start of the Hellmann trial. I read various articles, websites, etc., trying to understand the case against them. I was told (by guilters) to read Massei, and once I did, I was convinced there was no case against them. Further study convinced me they are completely innocent.
What I am pointing out is that the average person, reading an occasional article, watching an interview on the Today show, watching an occasional Nancy Grace type program, doesn't do what people here have done. They don't look at all the pictures, read the judge's reports, etc. Once you do that, most people get it. But I see a lot of writing by supposedly educated people saying things like, "Knox supporters don't understand the process in Italy". If that is their opinion, I know they haven't really looked into the case closely enough, because, as said here earlier, this is not about comparing justice systems, it is about wrongful convictions. That concept transcends cultures and geographic boundries.
