> The "DoJ... 3%" reference was in the 20C3 talk (2013) by RD & JA at about 11 minutes in. I've got the video and don't recall where I got it but it wasn't YouTube. The talk at that point was about the perception of Tor and a slide was put up with four bullet points, the first of which was "Doj's aborted study finding 3% bad content on the Tor network".
