What I think needs to exist is a similar protection government has, national interest. I think there should be, in all democracies, a defence of national interest. The law should never be allowed to obstruct the truth.
Have there been examples in the Snowden materials of how the US spies on "adversaries" such as Russia and China? I didn't even realize that those were adversaries in the traditional sense that justifies such intrusions in everyone's lives.
The second one seems to be more about the British spying on the Middle East of which they share information with the NSA. I admit I skimmed it but does it accuse the NSA of spying on adversaries such as China and Russia?
So far, they just seem to spy on everyone.
