found in raffaele's apartment. >> in the case of the knife, the media mantra on this, the thing they kept repeating all over it was that it had meredith's dna only the blade and amanda's on the handle. it did not have meredith's dna. if a spoon was taken from your kitchen drawer and tested by the same techniques, the spoon would be shown to have meredith kercher's dna on it. it was pseudoscience. >> the second piece of evidence was meredith's bra clasp, found at the crime scene, allegedly with raffaele's dna. >> they came back and brought it back. >> they didn't collect it for like six weeks. they kept kicking it around the room and then picking it up with the same gloves and putting it down. >> the defense tried to challenge the dna tests done on the knife and the bra clip, but the prosecution argued that all testing had been done correctly. the judge agreed and disallowed additional testing.
