I don't mean to hijack thread, but, based on what the FBI says it has going here, which they don't want to give up...
It would seem to me that the FBI should have been able to determine as an absolute fact whether Russia meddled in the election and the DNC leaks and wikileaks leaks or not.
They couldn't.
The unclassified DNI report of 12/29/2016 (which includes the FBI) gives a "high confidence" that it was the Russians.
""High Confidence" generally indicates that judgments are are based on high-quality information from multiple sources. High confidence in a judgment does not imply that the assessment is a fact or a certainty; such judgments might be wrong.”
Then, the Feds release this (which is supposedly how it was done):
How Russians Hacked
Yet the Feds are "confident".
"The use of common practices and methodologies is part of why the government is confident that both APT28 and APT29 are associated with RIS."
Still, no absolute fact it was the Russians.
And now we find out the FBI has tech tricks that can uncover & track anonymous surfing, yet still couldn't absolutely pin it on the Russians ?
