Ulbricht's argument to the effect that he wasn't properly charged with the murder-for-hire scheme was addressed in detail by the court:

It seems to me that if the Feds were confident about their murder-for-hire claim, they would have charged Ulbricht accordingly. That they chose not to do so indicates they were less than confident, and we should draw our conclusions accordingly.
For all I know he may well have been involved in murder for hire; I haven't paid close enough attention to the case to have an opinion. But I've followed too many hacker cases to accept unrebutted DOJ allegations as gospel truth.
The prosecution memo does not rebut this argument, it rebuts instead the clearly different but related argument that the murder-for-hire scheme was uncharged conduct which could therefore not be considered in sentencing. It was -- as they correctly point out -- charged, as it was one of the overt acts specifically laid out in the Count One narcotics trafficking conspiracy charge.
It is nevertheless inaccurate to say he was convicted of hiring a hitman, since a conspiracy conviction requires (as far as overt acts go) only a finding that the defendant committed at least one overt act in furtherance of the conspiracy, there were several overt acts charged in that count, and the verdict form did not direct the jury to return separate findings of fact on each charged overt act.
Capone went away for tax evasion, right?
The argument I'm challenging is the notion that the factual claim of Ulbricht's attempt to hire a hitman wasn't subjected to scrutiny during the trial. It was a specifically introduced factual claim, which Ulbricht's counsel was required to rebut.
