It might be worthwhile to discuss what the defense asked for at the first trial. Andrea Vogt wrote, “Lawyers for Knox and Sollecito, asked the court to approve an independent review of several contested pieces of forensic evidence, most notably the kitchen knife with Knox's DNA on the handle and what prosecutor's argue is the Kercher's on the blade, and a bra clasp with Sollecito's DNA.
Knox's lawyers also asked for a review of the luminol-enhanced footprints, the mark on the pillowcase that the prosecution argued was a woman's shoeprint, but which the defense argues is simply a bloody crease, and several other traces of DNA found in the flat Knox and Kercher shared…. The Kercher family's attorney, Francesco Maresca of Florence, argued, however, that the court already had plenty of material to review. ‘We all know that in all trials of this nature there are different analyses of forensic evidence made by the various expert witnesses,’ he said. ‘The court must now consider the seriousness and integrity of the experts' testimony.’
Prosecutor Manuela Comodi went a step farther, saying while she did not believe a review was necessary, she would she would ‘almost be pleased’ to see the results with regard to the prosecution's footprint expert analysis.”
The request was rejected. “Immediately after the judge's announcement, Sollecito bowed his head and briefly wept, as lawyers began haggling over court dates for closing arguments.”
