One issue with any potential trial for murder-for-hire is that the allegation as presented in the Maryland indictment has two problematic witnesses: DEA agent Carl Force who acted as the hitman, now in prison for embezzling cryptocurrency from the Silk Road case, and Curtis Green, the would-be victim in this case, who has previously insisted that Ulbricht was innocent of plotting his murder (and was also recently imprisoned for cocaine distribution last year, although I don't think that would be too relevant). Maybe the other allegations might have more meat on the bone, but they didn't make it on to any indictment.
