OK lets assume I let the droplet fall on my underwear and send it to a lab. They effortlessly find unknown DNA.
Now, I send my longjohns that I was wearing at the same time as the underwear to a lab and they find the SAME DNA PROFILE as was on the underwear. What does this cause you to believe? Hello??
Hello back. Your cognitive skills are failing you. I'm getting close to snapping point with you again. We were talking about your comment about the DNA being 'mixed' with blood. If the DNA was on the LJs before the blood fell on them, then the DNA would probably show up in a test. We have already accounted for the DNA itself being in multiple places before the murder.
To clarify:
As asserted by an FBI criminalist (TY, Dave), and should be readily apparent even to you, it is entirely possible to pick up someone's DNA (say, if you shake hands with some with a cough and get saliva and skin cells) and scratch your head and maybe touch your sweater, you will get the DNA in more than one place. In fact, this is one of the very bases of touch DNA.
This could conceivably have happened in JBR's case and I don't think anyone can dispute how much DNA she came into contact with on Christmas Day. Or her mother, who had had similar contact with many sources of DNA and may have had alien DNA on her (having by her timeline, not washed her hands or clothes before putting JBR to bed) and did touch JBR's undies and her longjohns - which she admitted to. Or the knickers may have had DNA on them from the factory and this may have touched the LJs - undies and LJs will have come into contact with one another. Obviously. This is precisely why so many DNA experts tell us to take care with touch DNA.
However, this eludes IDI.
And even if the DNA on JBR is not innocent, it still doesn't exclude the Ramseys as accomplices or of having some knowledge of the crime. Which IDI can't get through their skulls. The Ramseys would still have plenty to account for.
