True the DNA has not been disproved. How does one go about disproving that when the testing was scientifically incorrect?
For example the sample 36b tested negative for blood and was found to be not something of human origin or words to that effect.
In fact the sample was mis-quantified and lied about in the detention hearing when Stefanoni testified that it was ample in size..."a couple of hundred picograms" and later we discover that this was a lie. It was < 10 picograms and maybe zero picograms because at these quantification levels they are
too low to test any further... it is hard to tell here.
Contamination is one and actually the only possibility and in 2007 and even today in 2014 I don't think a sample of 5 or 10 picograms can be used in court no matter who does the testing. It is just too likely to be contamination...the risk of error is so high as to be unusable as evidence of any sort. So why disprove?
Yes RS DNA was on the clasp...so were three other guys. Who do you suppose these other guys were and how did they get on that clasp??? A clasp that just so happened to be rusted and destroyed and is impossible to retest due to improper basic storage technique.
What do we need to disprove? First let the other three guys disprove and then we will disprove RS DNA...wait... Was it a full DNA sample or some Y type indications? Actually I contend that if RS unhooked MK bra then his shoe prints need to be somewhere in this room...and BTW if he ran barefoot during this murder and made the footprint image on the bathmat....where is the "negative image" ...you know...the place where he picked up that blood? Remembering that for Guede this blood washed down onto his foot from his blood covered pant leg...probably filled his shoe right up and soaked his foot.
That is Guedes big toe BTW....on the bath mat...impossible to be RS big fat big toe...a perfect match to Guedes rather normal looking big toe though...

Have you ever seem Yummi/Machs analysis of that...all the hand drawn little arrows? Its funny really.
I think the burden should be on the prosecution to prove beyond doubt that these two DNA samples are safe and reliable and re-testable. Have they even come close to doing that? Not in the real world...not even close. In fact all indicators are that these two samples are suspiciously corrupt in nature. Mis-collected, subjected to secret test procedures and still no control proof or even full disclosure of the raw data in the form of EDF's.
Meanwhile the bra clasp is suspiciously destroyed and the knife which never matched the bed sheet imprint ...not even closely...has failed to reveal any MK DNA after several retests. A starch granule was found and another low template number sample purported to be a match to Knox but which can never be reliable because of its size and improper handling at collection. The 36I sample was a show...it is just as likely to be a incorrect result as well. The peer review on that test seems to be still out.
