It's so fucked up what they are doing with the Roman Sterlingov case. I can't even believe what I am reading:

Mr. Sterlingov’s withdrawal pattern from Bitcoin Fog is entirely consistent with user withdrawals; this is corroborated by the Search Warrant Affidavit signed by IRS-CI Special Agent Leo Rovensky “These withdrawals occurred sporadically and in the same manner as a regular user.” The affidavit goes on to make a leap of logic stating that the likely reason Mr. Sterlingov’s withdrawals match other user withdrawals is that he was trying to obfuscate his ownership. However, we know that Mr. Sterlingov deposited his funds into exchanges that required him to upload a copy of his government ID and take a selfie. The conclusion made by IRS-CI Special Agent Leo Rovensky that Mr. Sterlingov is the administrator of Bitcoin Fog is unfounded and illogical.

Mr. Sterlingov’s use of other privacy services like Wasabi, CoinJoin, Bitmixer, and Mt Gox CoinJoins demonstrate he was a user of privacy services, not that he controlled them.
