That saddest thing about Russiagate...
...is that I'm not sure whether the FSB or my own (Yank) government lies to me more often.
For example, when Maria Butina was arrested in Washington D.C., the initial coverage in the Washington Post (which was based on court documents) used blurbs like this one to portray her as a serious Russian spy:
"In a note in March 2017, Torshin wrote, 'You have upstaged Anna Chapman,' a reference to a Russian spy who had lived freely in the United States for years before her 2010 arrest."
The average dolt who reads the Post would take that as a smoking gun - in short, Torshin admitting that Butina was a spy and complimenting her performance.
Anyone smarter than the average Post reader would remember that Chapman was a failed spy (making it a dubious compliment). They would also wonder why an FSB agent stationed in an unfriendly place would make purposeless self-incriminating statements by e-mail, encrypted or not. (Any communication with Russians makes you a statistical anomaly among US residents, and the NSA tends to notice those things.)
The full quote from Torshin - which the FBI had in-hand - was "You have upstaged Anna Chapman. She poses with toy pistols, while you are being published with real ones."
It had exactly nothing to do with spying, and was a reference to Chapman's publicity stunts since she returned to Russia.
I'm not sure whether the FBI tried to mislead the judge, or whether the Post tried to mislead its own readers, but at least one of those two institutions cynically lied to the public.
