Bullshit. We managed to survive 200 years without aggressive widespread domestic spying on citizens. That is the hallmark of totalitarian nations...period.
It is not the same as spying on other nations.
You are a total fool to think such information is not used for systemic abuse politically, for repression of dissent, and for the retention of power by the establishment. Every 3 days the NSA collects more sheets of data than the Stasi did in its entire 40 year existence.
And again, when a government creates open borders, arms cartels, arms al qeida, brings in hundreds of thousands of moslems of every stripe,,,, they do NOT get to whine that they need to have domestic spying to keep me safe.
What data do you think NSA has been collecting?
