DNA in the Amanda Knox Case: Experts Refute DNA Evidence Successfully

Wired has a great article today detailing the problems found in the DNA evidence presented by the prosecution in the Amanda Knox murder trial, written by John Timmer for Ars Technica and entitled, "Courtroom Science Drama: The Saga of Amanda Knox’s DNA."  

One of their experts is Dr. Lawrence Koblinsky of the John Jay College of Criminal Justice in New York.  You may have seen him on TV.

Point being that the DNA evidence used in the Knox trial not only served as a major tool for the prosecution to have Amanda Knox found guilty of murder, it was also a key factor used by her defense team on appeal to achieve her release.  Arguments post-conviction included not only that Italian law enforcement may have compromised the DNA evidence during their investigation, but also that DNA evidence found on the murder weapon (a knife) was miniscule and irrevocably tainted in the attempt to amplify that tiny amount into something bigger and therefore, easier to analyze. 

My prediction: the Amanda Knox case will serve to publicize the weaknesses in DNA evidence and more criminal defense attorneys - both at trial and on appeal - not only will spend more time and effort challenging DNA evidence, the likelihood is increasing that their efforts will be worthwhile.
