Ross Ullbricht did not get a fair trial. Evidence was withheld to protect the agents, who also stole Bitcoins.
The murder charges was never used in court, they only fabricated that story, to make him look bad, and the sentence is clear evidence of that.
I doubt they were fabricated but it may have been entrapment. If you're going to say evidence was fabricated then you might as well say the entire evidence they had against him was fabricated too.
There are people much more more familiar with this case, who are saying exactly that: Most evidence is fabricated. There were a lot of lies, about how they got certain data(since, what they said didn't make sense in a technical way). There was evidence used, that no court should accept, since they are easily manipulated.
Also: If there was entrapment, that is illegal in the USA, as far as I know. He is not convicted for the murder charge, there isn't even a prosecution for that and there will not be one.
Well all the ones who are saying this are obviously pro Ross and are going to say evidence was fabricated. When you get caught at your laptop logged in as DPR this argument loses a lot of credibility. I'm sure the trail wasn't fair but they didn't really need to fabricate anything when everyone can see what was going on.
