The murder for hire was done with the admin account which was called "Dread Pirate Roberts" from the novel "The Princess Bride". The thing about the name is that is passed on over and over. The admin has claimed multiple times that he is not the original nor first administrator (Ross) of the silk road.
In addition you have the guy that was supposed to be murdered also claiming that it could not have been Ross.
The murder for hire case was very weak and then in addition you had the two federal agents working the murder for hire case charged for stealing bitcoins.
This is silly whataboutism. They have plenty of evidence, including PST/PDT timestamps and proof he logged out of other personal accounts when he logged into that account, that suggested it was him. Despite his claims, they watched him extensively and found no indication that anyone else was posing as DPR.
