One thing I`ve understood; in this case there is no way, that any witness, that doesn`t fit in the agenda of the Knox-supporters, can be found (in their opinion) reliable.
The four independent witnesses, that heard the scream and/or heard running of people shortly after that, are useless because all of them are retarded daydreamer, as they falsely connect their "imaginative" hearing of the scream to a total "common" day, on which a negligibility like a murder in their neighbourhood had just occured. One of them even had such a great fantasy, that she heard such a harrowing scream, that she couldn`t sleep anymore that night and obviously is haunted by this event up to the present day. If this wasn`t enough, all of them went to court to tell their fantasy story, because, whether thier story is true or not, it doesn`t really matter, because their terstimony would be correlated to a totally unimportant matter like murder.
The witness, who saw AK & RS at the basketball court at the crucial time on Nov1, is also rubbish, because he`s homeless.
The witness, who is a shopowner, and who saw AK early in the morning of Nov2, is a bloody liar. He lied, because either he had fun seeing at least one "innocent" person rot in jail for 30 years due to his testimony or because he was just bored, and through his evilness, he thought about creating a story, which would bring one of the accused in big trouble, as he thought they were guilty by his knowledge of the case, which came from his newspaper study.
I think it would be far more productive to engage with the evidence for and against each witness being reliable and accurate, than to just pretend that they are all being dismissed because we want Knox and Sollecito to be innocent.
It would be equally unproductive for me to assert that all guilters are irrational and believe whatever suits them without any regard for the actual evidence. Even if it were true, it would get us nowhere to say it.
First of all I have no medical expertise at all and I don`t believe in getting it through googling some papers, that deal with the issue of estimating Tod in terms of pathology.
I very much believe in reading and understanding the relevant literature, rather than taking the word of authority figures whose testimony conflicts with the best available literature on the topic.
The ability to do so is why we have the scientific literature in the first place. Scientific facts must be peer-reviewed and publicly accessible. They are not mystical secrets which only the elect may apprehend, they are printed in black and white in journals anyone can read.
If a supposed expert contradicts the literature, then the supposed expert damned well better have a publishable paper in the pipeline backing up their position. Otherwise they're just wrong, and you don't need a relevant PhD to know it.
I just wanted to approach the issue in mathematical respect. First of all, it`s funny to see, that your knowledge of the method of "Estimating ToD based on stomach/intestinal contents" and your "knowledge" of the autopsy details in this case leads you to a time frame of 1.5 hours, in which ToD must have occured. This again implies, that this method gives a lot of space in terms of statistical interpretation. What I`ve said before, the occurance of such an event (be it stomach emptying times, grade of digestion or whatever) is of stochastical nature. That means (please note, that the only thing I try to point out is the mathematical side of such a method; if my following examples are nonsense in terms of pathology, that doesn`t change anything in the mathematical approach on such a method), if you reproduce, say 3 times the exact same conditions, for example: if a person (theoretically) eats three times the same steak under the exact same conditions (exactly the same steak, exactely the same day and time, eats the steak in exactly the same way etc. etc.) and then you measure the value, you are interested in (say percentage of the steak, that has left your stomach in the cause of digestion) 3 times in exact the same way, for example 3 hours later you get three different measured values. Why? The conditions were the same all three times.
The answer is, that this event is of stochastical nature, and even under the same conditions you get different measured values.
But the reality of measurement is far worse, as the measurements are adulterated by systematical errors, as for example imprecise measurement devices, incompetence of the person, who is doing the measurement etc..
Another problem is, that, for estimating the real parameters for the distribution function (in "our" case a normal-distribution) of our random-variable ToD, that is mean-value and variance, you need an extremly big control sample (the bigger the control sample the better the estimation of the unknown parameters(mean value, variance)). In "our" case, this would mean (theoretically) reproducing the way of death of MK (I know that sounds horrible) numerous times and then, every time, measure the value you are interested in. What a statistician is doing in the end after having acquired all the "relevant" data is the following. Through his data, he estiamtes the two relevant parameters (mean-value, variance) with a given formula and then, with the help of these two parameters, he builds a, say 95%-confidence intervall for the mean value (that is an intervall, which for "our" random variable Tod would be for example: 21:15-24:00), which says the following: the real value of the parameter mean-value (in our case the mean-value is also the value, which has the highest probability, which is a special attribute of the normal-distribution) lies with probability of 95% in the calculated intervall (21:30-24:00).
So, which conclusion can be drawn for "our case". First of all, our control sample has the size one, which means we can`t estimate the variance with the given mathematical formula. To "solve" this problem, as I suspect was done, you look for cases, which are similar to the Mk-case. It is cases, where, for example, a similar degree of the last meal was digested and, where the date of last meal and date of ToD are known , weigth of the person is similar to MK etc.. As said, the condition of those cases are just similar to these in "our" case and not exacly the same. Then, there are systematical errors, that were made in these cases, too (which add up, when they are evaluated). This means, that the "expansion" of our control sample is to a remarkable degree defective. Of course , the data acquired in our case is to some degree defective, too (systematical errors)
So, what we get, in the end, is, a defective (confidence)-intervall of time, which only tells us, that the event (ToD in "our" case) with the highest probability lies in there, with probability of, as said, for example 95%.
Taking all this into account, the claim, that Tod must have occured shortly after 21:00 is ridiculous.
You were fine right up until the end.
There is a degree of error in any scientific measurement, yes. With the correct mathematical tools you can describe the possible error range and the likelihood of an error of a given magnitude, yes.
But then you jump from this to "and therefore nobody can ever know anything, TA-DAH! SHE'S GUILTY!". Sorry, but we can know all sorts of things, within given margins of error. A time of death of 21:00 is already getting implausibly late based on Meredith's stomach contents, knowing what we do about the range of possible error. Only because we know Meredith was alive until shortly before then can we rule out a much earlier time of death.
Of course, you`re right, that physics is an "exact", science, but the measuring of physical values is far from exact, it`s defective and of statistical nature, as shown above.
The fact, that so many experts came to so different conclusions for ToD in respect to the size of the time intervals and placed them at so different times, speaks volumes for me in terms of reliability of this method.
So the published evidence says one thing, but four different prosecution witnesses said four different other things... and you conclude from this that nobody can possibly know the answer? How do you think the universe works? Do you think that when people are gathering hard data for a publication the universe sets out to trick them, and that to get to the real truth we need to ask prosecution witnesses in a highly controversial trial?
The witness testimonies are much more profundly for me in that respect.
The untrained human brain is terrible at weighing up evidence, and tends to put far more weight than it should on its perception of social communications and far less weight than it should on scientific data. That's why there are so many suckers who think "This guy seems legit... he has an honest face... I bet he really does have a free energy machine".
In the Knox case there are plenty of people making exactly the same mistake and thinking "Knox looks shifty... I think she lied about some stuff... I bet she really is a murderer despite the hard scientific fact that the prosecution narrative cannot be reconciled with the stomach evidence".
The trained human brain is aware of this tendency and looks at the hard evidence first, and forms hypotheses based on the hard evidence first. The hard evidence says that Knox and Sollecito were at home when Meredith Kercher died, and Rudy Guede was alone at the scene.
Finally this will be my last post on this thread, as it seems to be an unreachable task to change the belief of AK-supporters in her innocence, regardless of what had happened and what will happen.
It's a psychological fact that we only like to change our beliefs and behaviour a little at a time. You can get someone to make a small donation more easily than a large donation, but once they have made that small donation they are then more likely to make a large donation in the future. Once again this is characteristic behaviour arising from the monkey instincts of the untrained human's brain.
One of the hardest things scientists have to learn to do is to turn on a penny when the evidence calls for it. Even if you've spent twenty years assembling evidence for a pet theory you are expected to chuck it all in immediately if your worst enemy elegantly falsifies that pet theory. Even if you've spent months or years on the internet viciously defaming Amanda Knox, if the evidence proves her innocent you're expected to switch immediately to recognising her innocence.
You've obviously got some background in science or statistics: I think you know as well as I do that your attempt to cast doubt on the reliability of the stomach evidence just doesn't hold water. When you go to the best published data (which neither side in the trial did), you find out that Meredith could not possibly have been killed by Amanda or Raffaele. The stomach contents nail down the time of death to around 21:00 or not much later, and the computer records verify Amanda and Raffaele's alibi until 21:49 plus travel time.
Now the question is, are you going to act like a scientist and turn on a dime when the evidence tells you to?
