The mere presence of a foreign IP address or foreign country code does not in any way plainly establish that the person on the other end of the communication is not an American. There are millions of Americans living outside of the US. For the government and its secret security services conducting universal surveillance to make such a claim or imply as such and the establishment press to go along with that concept amounts to nothing more than reliance on the ignorance of US voters to trick them that this surveillance is not harmful (not a big effort it seems). Chalk that up to one more way that the US government treats an American living offshore kinda sucks.
To be sure, as the Post report points out, most of the violations were unintended, and the percentage of violations was quite small, given the vast amount of activity that the NSA engages in. But that hardly obviates one’s concerns. And some of the violations are quite serious, consisting, as they do, of “unauthorized access to intercepted communications, the distribution of protected content and the use of automated systems without built-in safeguards to prevent unlawful surveillance.”
