Smelly Squirrel,
So, as per your requirement that competing hypothesis should be compared, contrasted and ranked, what in your estimation should have been the best story?
If RDI, I think their best story would be that they found her dead in the morning.
One thing about the story which to me leans (paradoxically) towards IDI is the lack of an obvious entry point. I think there are possible points, but no obvious site that you can say that must have been it. If RDI, I would think they would have done more to show where a break-in occurred. JR has even downplayed the basement window since the beginning, saying he thought any break was from when he broke in (trying not to be too obvious? maybe).
Of course, an intruder may have had a key or a door may have been unlocked, as well.
You are being unduly unfair to Whaleshark here. There is no requirement to disconfirm alternative theories.
TherI could be reading wrong, but there is a responsibility to not mislead by either misrepresenting the evidence by making it say more than it does, or by portraying it as though only an RDI interpretation is possible.
There may be infinitely many depending on the evidence. Also competing theories might be completely consistent with the evidence, consider the size-12 feature, it has two different explanations. Currently neither can be confirmed or disconfirmed.
Agreed.
Consider IDI vs RDI: Whaleshark might come back to you and say on IDI There is no forensic evidence that links to anyone at all. Whereas with RDI the forensic evidence linking to the R's there is too much to list.
There is unidentified DNA.
Consider JR's shirt fibers found on the size-12's!
This is an example misrepresenting the evidence. First off, this information comes from an interview, where it's unknown how factual anything they said is. When pressed by Wood, they wouldn't show any report.
Even allowing the information is true, they do not say "fibers from JR's shirt were found in the underwear." The scientific claim would be that fibers consistent with the shirt were found. There's a significant difference.
Also needed for putting that evidence in context is what, if any, other fibers were found. Nobody here has seen the actual reports. If there are unidentified fibers and in greater numbers, that would diminish the importance of these fibers.
Having said that, I do think if fibers matching his shirt were found, that that is damning evidence for JR. Depending on how rare the fiber type is (saying it's from an "Israeli shirt" doesn't tell me that), I would find it very convincing toward his guilt unless he can explain how it got there (secondary transfer? from PR? from someone he saw that night?).
However, the fact of the lack of any prosecution then leads me to think this fiber evidence is not so definitive. We are looking at the evidence through a glass very darkly. We don't know what they have.
