Excellent points, Radster. And the same points that I was trying to raise by poking the hornet's nest..

As you say, poking those 446+ small holes of doubt will presumably be the strategy.
The only thing on which I would disagree with you is that you say that Raney may get away with murder. But if that doubt exists, on all points, how do we KNOW that he may get away with murder? May he, in fact, actually be innocent? I don't know, and I haven't been following that case. But if he is FOUND not guilty, then shouldn't we assume that he is in fact - not guilty?
I'm not talking about an O J Simpson situation here - but the Leanne Holland case haunts me somewhat, as I can remember when it all hit the fan back in 1991. Everyone, including the police, had Graham Stafford guilty from the outset. It was all circumstantial. And of course the forensics weren't as sophisticated back then - but maybe they're not as sophisticated now as they may be in another 20 years time either? But now his conviction has been quashed, and I read yesterday that they are about to charge someone - presumably somebody else.
Poking those little holes of doubt into every point raised is a good defence strategy, and you can bet that GBC's legal team will be following the Raney case closely and taking pointers on how to do it.
What the police - and the rest of us - REALLY need is that one smoking gun piece of evidence, the FACT that cannot be disputed, that irrevocably ties the culprit (GBC or otherwise) to the crime. Maybe the prosecution has that - we don't know. But if they don't, then poking all those little doubt holes may become very frustrating for all those following the case.
