About DPR:
Perhaps the most shocking revelation in the Justice Departments argument against Ulbrichts petition for bail is that he allegedly ordered not two but six executions. Unfortunately for DPR, he appears to have gotten scammed out of the money he paid for each hit (approximately a half million dollars in Bitcoins in total). On the bright side, despite the fact that Ulbricht said he received visual confirmation of the executions, the government says it was unable to confirm that any of the killings were ever carried out.
The government documents leave open several questions about the Silk Road merchant DPR hired to carry out the planned killings a user whod adopted the nickname redandwhite (apparently a well-worn nickname of the Hells Angels motorcycle gang). Was he a government informant who was working with federal prosecutors to nab Ulbricht, or was he just one of many Internet predators who make a living scamming the scammers?

Honestly for several months I was in awe of what that guy's security must have been like, I sat and worked out what type of system setup I would have run and then analyzed it from a forensics point of view. I came to the conclusion he must have been pretty damn clever. I've never been so wrong. Guy was a freakin clown. Probably blinded by his egotism.
