It's just unfortunate that Trump, and now, excessive pardons are politically polarized, which could cloud the fact that justice was done today. I don't credit Trump in any way for doing "the right thing" or even having a principled position regarding Ross' case. Clearly, others with influence on Trump convinced him to sign it. It doesn't matter how the pardon happened. Biden should have already pardoned Ross because that crazy sentence shouldn't have happened in the first place.
Biden did commute the sentence of several other non-violent cases just last week or thereabouts, and Trump has been talking about Ulbricht for quite some time so it's not a complete surprise.
I guess the whole "murder for hire" thing excluded him from the "non-violent" category. But how that got tacked on seems very odd; the judge basically said "we didn't really handle it in the court case and it wasn't a charge, but it was mentioned a few times and it seemed basically true, so I included it in the sentencing". Like, ehh, okay?
To be honest, I don't really understand much of the logic ("logic") of the US justice system....
