I'm kind of confused. 10 years ago a guy stole from an illegal underground operation and today, years later after it was shutdown, someone form the government finally found them and brought them to justice? Who reported the crime and who's justice is the government doing this for? "Ring Ring" ... "Ross, you got a call from the government" ... "Hello Mr. Ulbricht, we'd like to let you know that we finally caught the thief that stole from you, justice has been served, I hope this brings you some peace as you carry on your life sentence." Like...WHAT?! Or did the government just want to seize the money? Maybe I'm missing context on who this guy was, but the article just makes it sound like some guy who managed to scam an illegal marketplace. Like it seems like such a waste of time to track such a random thing down, unless they were working on punishing every person who ever interacted with that site?
