Of course, by now you know about the „Five Eyes“ coalition of the signals intelligence agencies of the US, UK, Canada, Australia and New Zealand all sharing certain intelligence information between them. Some of the Snowden docs have made clear that this collaboration helps the various countries get around restrictions on „domestic“ surveillance by effectively offshoring it to other „friendly“ electronic spy agencies. Well, at least for now, it appears that that the Five Eyes effort has lost an Eye.
Canada‘s signals intelligence agency, the Communications Security Establishment (CSE), has stopped sharing data with the other Four Eyes after realizing that it hadn‘t done a particularly good job of protecting the metadata it collected on Canadians.
