Remember, in my hypotheses I already voiced that the lawyer on team A has convinced me that we cannot know that the sample of intestines were AA's, and, I've asked you and your lawyers on team B to convince me that the sample was AA's. I started with the concern of the chain of custody. You and others have jumped over this problem like it didn't exist. I'd call this a "leap of assumption".
No, I haven't jumped over it. My first point about chain of custody is that it isn't an end in itself, the requirement exists for a reason. That reason is to make sure that the samples are from the source they're alleged to be from.
An unbroken chain of custody of a single sample is one way to make sure that the sample is from the source it's alleged to be from, but it isn't the only way.
Independent confirmation of the identity of the source by analysis of another sample, preferably one which has had no contact with the sample in question, is another way of making sure that the first sample is from the source it's alleged to be from. That's been done in this case, your claim of irrelevance notwithstanding.
My second point about chain of custody is that there appears to be precedent in the courts for evidence to be admitted from old samples for which the chain of custody isn't secure, as long as there's some sort of independent confirmation of their identity, and that hence the "independent confirmation" standard is a perfectly valid one.
As for the "hair in an envelope in a book belonging to person A", thus far this is all I know about it. I don't know your source. I don't know who "person A' is. I don't know if they placed the hair in the book and later found it. Or was this book found on some book shelf in a bookstore? How can I comment without knowing anything about it. Nor do I know about the tests? Who tested the hair? Source, please. And, from the little I'm grasping, it appears the chain of custody might be a problem.
Who tested the hair? Mark Stoneking and Terry Melton. You really didn't know?
Again, I'm coming back to the issue about the chain of custody not being the goal here. The goal is to establish the origin of the sample. Two independent samples gave the same result in an mtDNA test. The hair sample wasn't associated with the hospital and it wasn't tested at the labs that tested the intestine sample, so a simple explanation based on cross-contamination or a one-time sample switch isn't going to cut it.
Both samples were alleged to have been from Anna Anderson, and both gave the same mtDNA result. As I said before, there's a limited number of explanations for this result.
1. Both samples actually were from Anna Anderson (person A).
2. Both samples had been tampered with, in different places and at different times, to switch Anna Anderson's samples to samples from another person (person B - to show that we're talking about just one other person).
3. Both samples - the intestine in the hospital and the hair in the book - were genuinely from another person (person B), despite the labelling as belonging to Anna Anderson, and there had been no tampering.
4. The two samples were from different people (persons B and C) and coincidentally gave the same result in the mtDNA test.
The whole chain-of-custody issue is to address explanation 2. The possibility that one sample was tampered with is quite high. The possibility that two samples, which had been located in different places, collected by different people, and analysed in different labs, were both tampered with in order to switch them for samples from a different person (person B), is a great deal lower.
Then the question becomes - is this extremely elaborate conspiracy to tamper independently with two different samples from different locations and tested in different labs really more likely than the notion that the samples were genuine?
As for lawyer on team B being good enough to convince me that there wasn't a reason, nor an opportunity nor enough money to tamper with the sample of the intestines, I assure you, in this hypotheses, the lawyer for team A did provide many very convincing reasons why people would have wanted the public to believe AA was FS and not GD Anastasia. Even today, as we write these post, there are political and personal reasons for people to want the door closed on this case, the brutal murders of the royal family, that has lasted 90 years.
My point here is that because of the hair sample, tampering with just the intestinal sample wouldn't have been any use. The intestinal sample would have then given a different result from what it gave, which means that it would have given a different result from the hair sample (which it didn't). Since they gave the same result, it means that neither was tampered with or that both were tampered with. The notion of just one of them being tampered with is ruled out.
All a lawyer on team A had to do is create doubt in the mind of the jurists and it's a real up hill battle for the opposition, lawyers on team B.
Interesting that you'd say that all you have to do is to create doubt in the mind of the jurists. While that may be true, creationists have managed to cast doubt about evolution in more than half the US population (and ditto for the climate change deniers and their PR success - and some of these people have been quite open about the fact that they're in the business of spreading doubt) but it doesn't mean that evolution is wrong or creationism is right, it just means that one side has better PR than the other. A clever lawyer can always cast doubt on scientific results because the American public is unfortunately predisposed to mistrust science and scientists. However, I would hope that this isn't really the standard you'd want to apply to this question. It's very easy to cast doubt on true results but it doesn't stop them being true.
So, what evidence can you provide to convince those of us on the jury? Because what you've presented thus far has been presented rather arrogantly, almost as if I the other jurists are obliged to believe you and your team because you know about the DNA/mtDNA tests. Well, we can't get to the tests until you can prove the sample is AA's.
It isn't arrogance, it's frustration. Every time I mention independent confirmation by a second sample, you just come back to the chain of custody of the first sample, as though this second sample was irrelevant. I have yet to hear a coherent explanation from any of the Anna Anderson supporters about how the intestinal sample and the hair sample gave the same result if they weren't both from her. Feel free to give a stab at it. Because that's the thing I'd be asking if I was a lawyer on the other side of the issue. I'd be asking whether you were claiming that a massive conspiracy was going on or whether you were claiming that it was an incredible coincidence. Which is really another way of asking why, if it walks like a duck and quacks like a duck, you're so sure it's a caterpillar
