The subject of the electronic data files (.fsa) files comes up from time to time here and on the previous thread. In the previous thread some posters (BobTheDonkey) thought that the defense had a right to obtain them, and others (Fiona) thought that the prosecution should only release what the law stipulated, without specifying whether the electronic data files (or machine logs) was included. Some of the posters doubted that the files had not been released. Someone used the canard that since the defense did not attend the testing, they have no right to such files. The electronic data files allow the electropherograms to be constructed anew and reanalyzed by experts.
First, the release of the data files is so standard that a form to make the request is available at some websites, as I have previously documented. As forensic DNA expert and bioinformatics textbook author Dan Krane said about the Knox/Sollecito case, “The biggest concern that I personally have regarding this case is the refusal of the prosecution to provide the defense with a copy of the electronic data that underlies the DNA test results -- that is virtually unheard of world- wide today and it would be especially important to review that data in a case such as this which seems to involve such low level samples.”
The notion that the defense gave up the right to these files by not attending the testing is pernicious nonsense, promulgated by those who should know better (having been told repeated why they were wrong). I have addressed this before, and will only give two arguments this time. Professors Adriano Tagliabracci and Gregory Hampikian did not become involved with this case until long after the testing was done, so how could they possibly be able to attend. More fundamentally, the .fsa files are needed to reanalyze the data; merely watching someone do the testing is completely useless as a substitute. Moreover, given that Dr. Tagliabracci disputed six the interpretation of six loci, the need for experts to actually see the raw data, not someone’s interpretation of the data, should be obvious.
The citations I have repeatedly given about Dr. Hampikian’s visit to Ireland in March/April of this year make it clear that the files he requested were not given to him. The open letter makes it clear that they were not given to Dr. Johnson, either. Raffaele's appeal document also indicates that Dr. Pascali asked for files and was refused. How anyone can oppose the principle of discovery with respect to this case is beyond comprehension.
