Hew Raymond Griffiths, had never been to the US. He was extradited from Australia to the US for something that isn't considered a crime in Australia.

The irony is this part: "Griffiths finally returned to Australia on 2 March 2008, after 5 weeks as an illegal alien in the US immigration detention system following his release from prison on 26 January 2008 (Australia Day). A condition of his repatriation to Australia was that he never again re-enter the United States of America, a country he had never visited before being extradited to it."

I'm left scratching my head at this as well. I'm assuming (without reading into it) they are arguing that it was U.S. copy righted material that was taken, and distributed on U.S. soil (i.e. the internet).

Julian Assange faces similar offense[1], though in this case they are claiming national security as opposed to copy right infringement.

It happens often. See "Mr. Nice" https://en.wikipedia.org/wiki/Mr_Nice_(book) - he was a pot smuggler who had never entered the states and was not a UK citizen but the DEA managed to extradite him anyway.

One word: overreach

Imperialism. What the US says goes.
