Costs to the US?? What do you mean?? But people have been blathering for weeks on HackerNews that the US spying on anyone who's a foreigner is good and right and expected! Surely they can't have neglected to consider that there's only so long you can fuck with people's liberties, whether within your own borders or without, before the lie is revealed and the system build around it crumbles.
No, I won't buy it. I stand with HackerNews here. Spy on foreigners FTW!
