People sometimes complain about companies like Yahoo and Google and their buckling to Chinese Law. In fact, online gambling is legal and regulated in the UK and in Costa Rica where these sports books operate. But the US has no problems arresting forign citizens who have committed no crime on US soil and were in fact operating legitimate business in thier home countries. There is no difference between what the US did and you getting arrested on a flight layover in China for for publishing something about democracy on your website.
