Cf. this reminder of another recent FBI investigation:
Never in the history of world has a human being been so completely buried under a mountain of no evidence. Hillary Clinton can say there’s no evidence she sent classified emails until the evidence shows up, at which point there is no evidence she knew they were classified, until evidence of that shows up, at which point there is no evidence anyone got hold of it, until 400 people are willing to stake their lives that it was certainly compromised by sophisticated bad actors, at which point there is no evidence that it mattered.It does seem as if they are, lately, more devoted to finding "no evidence" than to finding evidence.
This came to mind listening to FBI Director James Comey’s interesting phraseology, carefully formulated, no doubt: “We found no evidence” and “We did not find clear evidence” and “[Hillary’s lawyers] deleted all emails they did not return to State, and the lawyers cleaned their devices in such a way as to preclude complete forensic recovery” (emphasis mine).
