When did I say that?
My trajectory on this case (as I've noted before) is that I heard the bare bones of the case and the verdict through the normal mainstream media. Then in April 2010 I happened to buy a book about the case: Darkness Descending (chiefly because it was in a "buy one, get one free" offer in WH Smiths

). Having read that book, I felt that Knox and Sollecito had to be guilty, but there were certain aspects that intrigued and concerned me. So I decided to see what information/debate there was online. I thus entered the hitherto (to me) murky and combative world of internet discussion forums. And as I learned more, I found that Darkness Descending had misrepresented several crucial facts - the ones that had led me to my initial belief in guilt. It didn't in fact take me long to conclude that in my opinion, there clearly was insufficient evidence to convict Knox or Sollecito.
Insofar as my holding any belief that Knox and Sollecito "were guilty, but that the courts did not prove this" goes, I don't think I've ever held that belief at all. As soon as I concluded that they should not be convicted of the murder, I concluded in parallel that there was also evidence pointing to their non-involvement. I would say that my belief in their factual innocence has strengthened over the past four and a half years or so, but I've
always stated that I am not 100% convinced of their factual innocence: in the absence of an unimpeachable alibi, only Knox, Sollecito and Guede know the factual truth.
But alongside that, I've always stated that it's wholly unnecessary to be 100% convinced of their factual innocence. I've often cited a hypothetical example to illustrate what I mean: that of a murder that occurred about half a mile away from where I live, at around 3-4am. I happened to be asleep alone on the night of the murder. I therefore don't have any sort of alibi. But in order to charge me with murder, far less convict me of it, the authorities are required to prove that I committed the crime. And in law and ethics within a modern democracy, if the accusations cannot be proved, then the person must be considered innocent. In that hypothetical example, only I (and the real murderer) would know with 100% certainty whether I was factually innocent.
