Ahhhh the old "The DNA is crap" argument.
Let's break it down...
LE brought in blood and cadaver dogs.
Neither should have alerted but Grime is on record saying Eddie the Cadaver dog got wildly excited when he entered 5a, which means he smelled cadaver. He went on to indicate in a few select spots in the apartment, Kate's clothing, cuddle cat, the Renault.
Bear in mind the dogs were owned and trained by the British police and Grime was actually PC Grime at the time. He got paid no matter what the dogs found, there was no ulterior motive.
So, swabs were taken at these few alert sites.
DNA consistent with Madeleine was found at these isolated spots - exactly where the dogs said it would be.
I could stop there - in most universes the DNA would be enough to charge the parents.
Team McCann worked their PR magic, dismissing the DNA as rubbish, doesn't prove anything.
The thing with the DNA is, it was low copy. This means it has to be amplified artificially which is when the scientific certainty is diluted - we had 15 out of 19 alleles belonging ONLY to Madeleine.
Evidentiary DNA has to be 100%. The DNA in Madeleine case is not 100% certainty, more like 80%.
What cannot be dismissed is the fact that McCann DNA existed at all in the cadaver alert sites.
In most cases, such as Caylees, the dogs alert is sufficient for LE to lay charges, per Casey Anthony. In the McCann case the reaction was to publicly denigrate both the dogs and the science - hence the "Dogs/DNA are crap" argument we see constantly regurgitated by McCann supporters.
All while totally ignoring genuine evidence - just like suppressing the e-fit.
What grieving, bereft parent does THAT!???!
