US wiretap figures don't match what the phone giants are saying — and that's a problem

"Albert Gidari, a former leading privacy lawyer who now serves as director of privacy at Stanford Law School's Center for Internet and Society, was first to notice a difference in the numbers. In the previous 2014 wiretap report, he noticed a twofold inconsistency between what the courts reported and what the cell giants reported.

In a blog post a year ago, he analyzed the numbers. Even taking into account the complexities of run-on and extended wiretaps, Gidari said the numbers still don't add up.

He told me on Tuesday -- a little over a year later -- he still can't figure it out.

"No one seems to have an adequate explanation," he said."
