The murderofmeredithkercher website is, unsurprisingly, a pro-guilty website as far as AK/RS are concerned. For each one of them, you'll find a pro-innocent one run by AK's team.
If anyone is interested (and prepared to check very carefully the sources (for the reasons above) have a read about Mignini (prosecutor) and Mario Spezi (pro-AK journalist) The old saying 6 of one and half a dozen of the other springs to mind.
RG went to jail on a so-called "rito abbreviato", basically coughing for the crime in order to get a shorter sentence. So a lot of evidence was not brought to the trial. He is now appealing (not sure if officially or just through his lawyers saying stuff on TV) on the basis of his conviction being for "murder together with person or persons unknown". His argument is that if those people are not Ak/RS, then the investigators either need to get looking for them, or overturn his conviction as well.
The buying cleaning fluids apparently never happened btw, the shop owner only came forward a year later and when their apartments were seized, no receipts were found.
It's interesting, IMO, that RS had the most famous and notorious defence lawyer in the land, the same woman who defended Berlusconi himself. Also interesting is that on the day of the final verdict, RS was apprehended crossing the border into Switerland (IIRC) with his new girlfriend. They were going on a "day trip" and of course he intended to come back into Italy the same day. This, despite him being present at almost every sitting of the trial prior to the verdict day.
I went from thinking they were definitely guilty, to definitely innocent, but very badly advised. And, I repeat, despite him having the most expensive lawyer in the land. It's still a case which is discussed over and over, on the web, and on Italian TV.
If anyone wants to do any proper reading though, a quick look through google pages shows the first 3 pages of hits are universally either guilty or innocent blogs from the respective camps. Dressed up as hard evidence and stating their own points of view as scientific fact. Pile'o'shite the lot of it I reckon.
If you do a search on MN for past threads on the case, there are some very detailed ones, some MNers (frankly) went a bit batshit in their pro-AK defence. Lots of useful documents were linked to though. It was all quite fascinating.
