It's remarkable that you think the NSA vacuuming up everything that flows through a domestic AT&T facility, per the Klein affidavit, merely "could" implicate Americans' private communications. Why not stipulate that it "will?" Also note that subsequent reporting has said that similar taps are in place at similar facilities, not just in San Francisco.

But the immunization for providers is not absolute; if requests go beyond what the law clearly permits, they're still vulnerable. Look for more litigation on this point.
