I specifically asked Professor Dan Krane, who heads a DNA forensics company, which was more important, to be present at the testing or to have access to the electronic data files. He said that to perform a case review, the electronic data files were very important, and the observation of the tests themselves were not that important. The prosecution never turned those critical EDFs over to the defense, and even the independent experts had to work hard to obtain them. The defense could have used the files to look for evidence of contamination or secondary transfer.
