Where does the US have jurisdiction? This is a legitimate question. What legal right does the US government have to enforce US laws on a foreigner who isn't in the US, for actions taken outside the US and which were not illegal in the country the person resides in? I'd legitimately like to know what sort of legal argument is used to justify this, because it sounds like a massive overreach by the United States. Regardless, arresting the CFO of a major corporation - the daughter of the CEO - in such a manner is an extremely aggressive act.
