Re: Good fences make good neighbours.
Don't take this personally but I don't give a flying fuck what US laws the USA thinks are valid outside their territory, they do not apply here (clue, I'm not in the USA). They also do not apply to US citizens here, US Marshals cannot come over here and pick up some US citizen and take him back to the USA for trial, not legally anyway. What happens when someone or something enters US territory is another matter - US laws apply in the USA.
Similarly citizens of, say, the Republic of Ireland should respect Irish laws concerning, say, data privacy and incidentally so should US citizens if they happen to be in the Republic of Ireland.
You may well say that Google can do what it likes with any data that it can get its sticky fingers on - I wouldn't bet on that situation lasting long once it becomes unpleasant for its customers.
