Oh you can fuck right off with that. It wasn't illegal to have a linking site in the UK yet that poor bastard was extradited for breaking US law, not having been there. If the US wants to do that kind of shit, then hell yes if they break laws of other countries they should get extradited there to face charges. I'm so sick of American exceptionalism.
I suppose we should extradite people to Iran for breaking Shariah too. This isn't American exceptionalism. Do you think China will extradite their military leaders for hacking US computers? Fat chance. If agents are caught in country breaking the law, they are fair game. That's the risk. Suggesting the US should extradite our leaders to China is armchair idiocy.
It is not ethical either, especially considering that the law itself is the exact same in the US(although NSA seems to be above it, which makes the whole issue even more contrversial IMO). Committing a crime abroad over the internet is no loophole to escape this fact, not even on moral grounds.
