My problem is this - no credible motive has been put forward
That is true and it is utterly irrelevant. There is no onus on the prosecution to provide motive and in fact it can never be any more than icing. What motive would you find acceptable? I personally cannot find a motive for Harold Shipman: but that does not mean he did not kill a lot of people. I cannot find a motive for Guerde either. But I do not think his conviction is flawed. Perhaps you do? If you think he is guilty and you think he was acting alone then do please explain how a petty thief suddenly turned into a sexual killer in any way which could not apply to the others.
(the theory that her boyfriend and her wanted someone to participate in their drug-fueled satanic ritual sex and killed her when she said no isn't a theory. It's a bad joke).
Described by the judge who committed them for trial as "fantasy". I infer it was not part of his reason for considering there was a case to answer. You?
The evidence was mishandled
The fact the bra clasp went missing for an extended period is poor: no disagreement there. What else you got?
and mostly circumstantial (person who lives in house has trace DNA in places).
Circumstantial evidence is important here, as it often is in murder cases.
No idea what point you are trying to establish with your second point: are you arguing that bloody footprints are common in most households? What different lives we all lead
The 'evidence' is a moving target and does not appear to be looked at skeptically.
Well I have to agree that some who are already convinced of Knox's innocence do not seem to be looking at it sceptically. So there we can agree
For instance, the prosecution claimed that the traces of Knox and Kercher's blood indicates Knox cleaned her own blood and Knox's off in the bathroom.
Missed that bit: can you cite for it please? All I saw them say is that there were three sites where Kerchner's blood was mixed with Knox's DNA. But there is a great deal to digest and so I may well have overlooked this claim and the reasoning behind it
This obviously calls for self-defense wounds on Knox, which... weren't present.
Interesting. Where are you getting the idea of self defence wounds? Didn't see the defence make that point. I saw them attribute the DNA to earrings removed in the bathroom cause a new piercing had become infected. Though how that got into the bidet was not made clear. Saw the prosecution witness refer to a fresh scratch on Knox's throat/neck but I did not see the prosecution make very much of it. So can you cite for that too, please?
Looked at with a skeptical eye, an explanation for how traces of blood could be possibly found in a bathroom two girls share presents itself...
In fact many do. They don't really account for a man's bloody footprint on the bath mat, though. Do they? Are you sure you know what sceptical means?
Moreover, what defenders of the Italian justice system are failing to note is that the police are already in hot water. Guilty or innocent, the interrogation was a complete farce.
Oops, there you go again.
Any time you manage to get your interrogation thrown out by a judge, you've managed to fail completely and utterly.
It was thrown out because it could not be properly established at what point Knox became a suspect, I think. Is there more to that?
Guilty or innocent, losing crucial evidence for over 40 days makes your police force a complete joke.
It is a problem: it is one thing in a sea of things. Not enough to constitute a complete joke, IMO. But your standards are clearly perfection. How common is that, where you are? Seems to me that some of what Skeptigirl has cited suggests not very. The question is how significant is it: I do not think anyone has yet made any coherent case as to why this is a case killer
Guilty or innocent, having a team that can't even properly identify if a knife has blood on it makes your police force a complete joke.
Well it would be if that were true: it isn't, so it ain't
So, regardless of Knox's guilt or innocence the police are obvious incompetents. That's the only conclusion. At that point, we simply are too frequently relying on the word of documented incompetents.
I don't really think you have made your case: I like the spluttering, though
