If you take anything the FBI or the American government has to say at face value then you are BLIND to how they operate...
It wouldn't surprise me if they used multiple alias's to first make him want/need these hits, then approach him as another user and offer to "take out" this person, that probably never existed. All in an effort to make sure he is locked up for life when they do catch him.
Look at it from their perspective, do you really think they would want a 20yo computer nerd to undermine all the massive efforts and expense they go to to oppress drug use, then see him walk free in a couple of years with millions hidden away.
Once his court day came and the judge decided that the crimes he committed wouldn't even justify a couple of years, after all he only launched a website offering free trade to the world, never actually sold anything illegal himself.
No no no, that wouldn't do for the FBI, so before catching him out for the "crimes" he committed, they had to cook up some real crimes, it's called entrapment, illegal in itself but something that the American gov love to do, and do it all to often. All this in an effort to ensure he couldn't walk free and that all the media would demonize him.
All I can say is glad i'm not american.. land of the free my ass.
Oh yeah , he was a hero and those damn government fascists want the poor Jesus v2.02 burned on a stick in all the media.
And he could bring peace to all the world , end hunger with his good for everything Silkroad project.
Free trade? well , he didn't get all those bitcoins from FREEEEEE trade.
