It's necessary to filter reports like this through three filters - incompetence, malevolence, and a genuine need for secrecy. Hard to know what to make of this report given those filters between the authors and readers. Personally, I'm unimpressed that, after 7 years or so of investigation, the answer seems to be "maybe it was nothing."
