All charges should be dropped, or commute the sentence.
Trump Had ‘Nothing to Do’ With Changing Roger Stone’s ‘Disgraceful’ Sentencing Memo.
Disgraced federal prosecutors asked a judge to Roger Stone to prison for as long as a violent criminal.
The corrupt prosecutors involved lied to the Department of Justice brass about what sentence they were going to request.

Who are the four prosecutors (Mueller people?) who cut and ran after being exposed for recommending a ridiculous 9 year prison sentence to a man that got caught up in an investigation that was illegal, the Mueller Scam, and shouldn’t ever even have started? 13 Angry Democrats?
Stone's corrupt prosecutors, some of whom were on the Mueller Trump-Russia team, ordered a dangerous armed pre-dawn raid on Stone's Florida home after tipping off CNN cameras that recorded the event.
The premise underlying the entire case against Stone, Trump-Russia collusion, of course has been mooted by the Mueller report.
Trump was furious with the unequal justice on display between Democrats and Republicans:

Whatever happened to Hillary campaign manager Podesta’s BROTHER? Wasn’t he caught, forced to leave his firm, with BIG BAD things to happen? Why did nothing ever happen to him, only to the “other” side?
He gave a couple of examples:

Is this the Judge that put Paul Manafort in SOLITARY CONFINEMENT, something that not even mobster Al Capone had to endure? How did she treat Crooked Hillary Clinton? Just asking!

FYI: The judge presiding over this case, Amy Berman Jackson, is the same judge who had Manafort and Gates and van der Zwaan.

The top brass at Main Justice were "shocked" "that prosecutors handling the case had recommended Monday night that Judge Amy Berman Jackson sentence 67-year-old Stone to between 87 and 108 months in prison. The corrupt prosecutors asserted in the Monday filing that a sentence much longer than the 15 to 21 months that the defense said was actually advisable under the federal sentencing guidelines.
The sentencing guidelines for manslaughter are 10-16 months.
