Despite the prosecutor Robert Mueller’s report, concluding that there is no evidence of Russian interference in the 2016 US elections, Washington is preparing new sanctions against Moscow.
It is unlikely that these Russian defendants will ever show up in an American courtroom. Therefore, no alleged evidence on which these allegations are based will be subject to adversarial review. This is essential, especially in the cyberworld, as leaked internal CIA documents have revealed that intelligence agencies can usurp the origin of an attack to give the impression that it came from a different country than the one who actually perpetrated it.
Although Robert Mueller's investigation was concluded with no proof of Russian collusion with the Trump campaign, it did conclude that Russia interfered in the 2016 election. Mueller's report determined that there were "two main Russian efforts to influence the 2016 election" (see further debunking by The Insider). It led indeed to US senators proposals to extend sanctions on Russia to deter it from further elections meddling.
The given conspiracy-like explanation that the incriminated Russians won't show up in the court in US and therefore are considered innocent is not sustainable. The unwillingness to show up in court could not be considered as a proof of innocence, but rather as disrespect to rule of law implementation proceedings. Russian prosecution also did not make any effort to interrogate the incriminated Russian citizens itself.
