Bongiorno complained about the lack of discovery in a 2009 address to the court (link provided some time ago). Dalla Vedova (see
quote I provided today) said that they still did not have the raw data as of 2011. Raw data does not mean an electronic copy of a egram; it means the data that are used to make the egrams. The lack of discovery goes beyond the lack of electronic data files and negative controls, however. In an interview Greg Hampikian said, "Its fairly routine in the US that I send a request and get what I want. But in the Knox case I havent been able to get a copy of the standard operating procedures of the lab and without that, its hard to see if they even followed their own guidelines."

Either the tweet posted at TJfMK is wrong, or Galati is wrong.
