Once more, for clarity (since what I thought were clear statements of my opinion seem to have mysteriously become incomprehensible): I think that Amanda Knox's own lawyer(s) made mistakes by seemingly not advising her to say and write nothing at all pertaining to the case. They compounded their mistake in my view by choosing to release her diary to the media.
So what makes you believe that Amanda had the benefit of legal counsel before talking to the police or writing her statement?
Or for that matter that it was Amanda's lawyers that released the first excerpts from her diary to the media?
