1. This is wiretapping, par excellence. Metadata in aggregate is shitloads of data, and tells a much more compelling story than the data.
2. Judicially supervised means the public needs to know about the process, and be able to challenge it. Some NSA agent visiting some "judge" who signs a piece of paper in the darkness is certainly not "judicial oversight".
3. US Congress is biased, and lubricated with money on a daily basis. It is beyond me how the US people continue to believe in a political system so cynical and so corrupt.
4. Quick expiration is irrelevant when these orders keep getting re-approved every single fucking time, and again, with no oversight whatsoever.
5. Um, yeah, so the NSA is apparently collecting data from 9 big internet companies. What's that about "further court orders"?
Congratulations, William Saletan, on the worst rebuttal ever of what is now, de facto and de jure, one of the largest surveillance states in the world.
