At the hearing on the motion for new trial, the DNA testimony was changed to an exclusion result. The trial court and court of appeals both dismissed the incongruent testimony as a change in semantics. State v.

And the county's crew was probably not exactly Paabo Svante. <br /><br />This is intriguing and it's really only taken off the past few years.

In NO WAY is this the lab analysts fault, and to presume such is poor taste. The lab analyts are simply following "code reds" protocols, poorly written by the DNA lab supervisors.<br /><br />"The forensic DNA community has been aware of substantial variance in mixture interpretation among laboratories since at least 2005 when the National Institute of Standards and Technology (“NIST”) first described the issue in an international study called MIX05."<br /><br />And it only took TEN YEARS to formally notify stakeholders? Peerwani, Barnard, DiMaio all run DNA labs -- did they do anything "intentionally wrong" in the past ten years? For those labs that have been using incorrect statistical procedures, they "did something wrong" intentionally and should be held accountable for being lazy and stupid (and training their lab analysts as such).<br /><br />And where the f*ck is ASCLD/LAB? Where is the DPS? Aren't these Texas labs accredited and considered to have picture perfect protocols (at least that's what the lab analyst testify to in a court room in front of a jury)? How can these DNA labs acquire accreditation when it is known that the statistical protocols are erroneous? Dare I say that the agencies are simply rubber-stamping accreditations for these lab, and collecting the hefty fees (paid by taxpayers)? Has any ever seen an ASCLD/LAB auditor testify as to the work they've done? No? I didn't think so. They don't believe in accountability.<br /><br />The "Oh, well" attitude among the "elite forensic DNA community" is vomit inducing.<br /><br />No tummy rubs for those that are "trying".Anonymousnoreply@blogger.com
