It's not possible to detail that in a short forum post. And I suspect whatever I say about their abnormal affect will be oversimplified and taken out of context. So I'll just have to say, get a degree in nursing or psychology and spend the next 30 years gaining experience with child abuse and grief and you'll probably be able to assess normal and abnormal grief yourself.Sorry, I don't really understand your point? What exactly did they do that can not be explained by "grieving in an unusual way"?
Of course cultural expressions of grief are normal. This is an example of you (and others) oversimplifying affect assessments and then denying anyone can assess normal and abnormal grieving.What exactly is "range of grieving behaviours"? Would you consider say, the actions of people at a jazz funeral to be outside this range?
I'm not talking about dirt like the stuff you grow plants in. I'm talking about kids touching a handrail or toys or anything else. Think of how many germs are on your hands. Now consider something as small as a germ. That's the amount of DNA we are talking about here.But is this the case? Were traces of dirt found under her fingernails or on the clothes?
As for evidence of dirty hands as I used the term, yes, the underwear was dirty, the house was messy, she didn't take a bath before bed. Of course there could have been an unrelated person's DNA coincidentally on her hands.
You aren't understanding what I've said.Depends on what "it" is....
No. As you know anything can be a UFO until you find out what it is, then it ceases to be a UFO. The "U" is there for a reason. I don't really understand why you would mention this with regards to the detection of deceit.
There are many methods of lie detecting that have been shown to be bunk.
That doesn't mean there cannot be one method which actually does work.
I did and I'll not post them for a 3rd time because you missed it.Care to provide some sources for the real supportable hypothesis?
Try re-reading the posts on this. Take a little more time thinking about the concept of baseline coincidental DNA findings.No, I don't think I have (I also never said the DNA was imaginary, but that's beside the point). You suggested that we need to establish "baselines" for contaminants, but you don't know if the DNA is contaminated until you analyse it. ...
Forensic labs use PCR quite a bit. Simply because it's essentially a reliable photo-copier of DNA. It doesn't really matter how much DNA you have on hand because it makes an evidence destroying piece of analysis less destructive. That's kind of the point of it.
Typically the use STR analysis to come up with a profile.
Baseline: the amount you would find without any crime having occurred.
Coincidental: unrelated to the crime, there by some other means.
I never said it did. I said the DNA was not conclusive proof of an intruder in the way people in the thread believe it is conclusive. Just as eyewitness accounts are not reliable, but for a very long time people were certain eyewitness accounts were reliable. Now we have overwhelming evidence they are not.And? This doesn't mean that all DNA analysis is wrong, nor does it mean that tiny amounts of DNA must belong to a source that is not a suspect.
People need to be careful believing such small amounts of recovered DNA are proof of a person's presence. Until we know how often extra DNA shows up on kids hands and in their crotches from scratching, we cannot say how conclusive or inconclusive the DNA findings in this case were. The DNA is real. It comes from a real person. But it has not been established how often this occurs on kids' hands and clothes when no crime has occurred.
PCR techniques have been around a long time. Only recently have police begun looking for traces of DNA not related to a specimen or swab sample. Try re-reading the FBI paper I cited to see the difference. In one case you swab a suspicious spot that looks like blood or semen or sweat or spit or skin oils or a hair follicle. In the case I am referring to you just look for DNA on surfaces that no body fluid specimen can be seen on and that represents a new forensics technique..So in other words you mean all techniques developed and refined since 1996?
That's only how you treat the evidence, it isn't a principle that suggests the evidence is or is not actually part of the case.Except that everything suspicious (like this DNA) in a crime is of criminal significance until shown otherwise.
