But they have no jurisdiction as he was not doing that IN the US. When the Pirate Bay guys were persecuted, the US got Sweden to convict them. They weren't extradited to the US.
Well they've been arguing over that in various court for over ten years. They didn't just charge him with copyright infringement which itself would probably not be extraditable:
>..charged in 2012 with engaging in a racketeering conspiracy, conspiring to commit copyright infringement, conspiring to commit money laundering and two counts of criminal copyright infringement.
Often with US law enforcement where there's a will there's a way even if it doesn't strictly stick to normal legal practices. See also Assange, and if you read Howard Marks book Mr Nice there's another example of where they got him in an unconventional way. Plus of course a variety of drone assassinations.
He has US victims though. Fraudsters aren't absolved of responsibility in the USA just because they operate outside the border, and the same can be true of other crimes.
