The biases of the jurors is a NON-ISSUE; it takes a unanimous verdict to convict and Roger Stone was guilty as hell. NOBODY DISPUTES THAT!
Ironically, this is very analogous to the Impeachment Trial of a few weeks ago. Donald Trump was also GUILTY of technical violation of laws, inappropriate coersion of a foreign official (albeit unsuccessful), and generally acting like an ass-hole. The Senate's conclusion was NOT that "he didn't do anything wrong," which is how various D & R politicians want to portray it, but rather that his offenses did not warrant removal from office, ESPECIALLY with a Presidential election coming in a few months.
Roger Stone deserves some punishment. 9 months in a Federal prison alongside Bernie Madoff. That's it.
But the DoJ sentencing recommendation was a political DARE, directed at President Trump by Never-Trump government lawyers. In effect, "We are going to get the most outrageous sentence possible for this bastard, and DARE YOU TO PARDON HIM!"
Knowing how the Democrats and the Media will excoriate him if/when he does.
And depending on what the Judge does, this is still playing out. A pox on the Democrats who are whining about "interference with the justice process." AG Barr is going to shove that right up their asses when he testifies in March.
