This is a good summation from a front-pager at Balloon Juice, and he sums up quite nicely my own observations so I'm going to just copy and paste his words:
While everyone is correctly pointing out the terrible discrepancies in our criminal justice system, it is important to remember that Paul Manafort's sentencing today is not the end of this story. Next week Manafort will appear before Judge Amy Berman Jackson in Federal district court in DC. It was Judge Jackson who ruled that Manafort had, in fact, lied, obstructed, and witness tampered in regard to the Special Counsel, his investigators, and his prosecutors post trial and conviction in her court. And it is Judge Jackson who will sentence Paul Manafort next week. Unlike Judge Ellis, who is a well known crank and who, in a properly functioning political system with two actually functional political parties concerned about the general welfare, the rule of law, and the common weal, would have been removed from the bench a long time ago, Judge Jackson is considered to be a jurist who takes her responsibilities seriously. Do not expect Judge Jackson to be lenient. And don't expect her to ignore actual facts to state that Manafort had previously led a blameless life. Do expect her to hand down a sentence with teeth in it. It is entirely possible that Judge Ellis departed from the sentencing guidelines because he knew Judge Jackson wouldn't. Doing something like that fits with his history of contrarianism masquerading as jurisprudence. Regardless, Paul Manafort will die in prison. And we should all be thankful for that.
Actually, that was the first thing I thought of when I heard about that 4 year sentence… wait until next week.
