Guys don't believe the assassination story so quickly. According to the official documents nobody seems to have actually been killed or even exist by the alleged names recovered from Silk Road servers, which have been in FBI custody...
That kind of personality seems totally out of character for DPR. I don't know him but his postings show clear thoughtfulness, like his response to the closing of Atlantis, or his posted rules for SR instead of letting it be an "I don't care what you do, just pay me bitcoins" environment. Hardly seems the type to be ruthless about murder. On the other hand the Feds would look good framed that way, like the heroes who shut down this site with illegal (according to US law) drugs from this clearly evil person.
Before you convict DPR keep in mind the assassination target seems not to exist.
If you read we all agree on the fact DPR was scammed, it's pretty much clear on the affidavit. The thing is that it looks like he was willing to commit that murder.
Was he? Why do you think we're all smarter than him? He may have well know that he was being scammed and used the hit thing as a bargaining chip to pay only $150K instead of $500K. It's a very considerable difference, after all. Many of you would kill just to get your hands on those $350K he saved
