Is it surveillance if only computers are watching?

Robert J. Litt, the NSA General Counsel, participated in a panel discussion last week giving some official details on the NSA surveillance programs. The video is here. Litt acknowledges certain things and makes other categorical denials, consistent with the denials President Obama has made that the government is not listening in on all our telephone calls. Because Litt kept referring to notes, it seems fair to assume he was choosing his words carefully, though his language and presentation style was informal and not robotic. Litt first addresses the "telephone metadata" collection, which he says is authorized under Section 215 of the PATRIOT Act. Litt points out that the authorizing language is there for everyone to see, and here it is. It is entitled "Access to certain business records for foreign intelligence and international terrorism investigations"and it describes how certain government officials

may make an application for an order requiring the production of any tangible things (including books, records, papers, documents, and other items) for an investigation to obtain foreign intelligence information not concerning a United States person or to protect against international terrorism or clandestine intelligence activities, provided that such investigation of a United States person is not conducted solely upon the basis of activities protected by the first amendment to the Constitution.

Telephone call metadata, numbers calling and called and time of call, are surely business records of the phone companies (how else could they produce monthly bills?) and there is a long history of court affirmation that no wiretap order is needed for law enforcement to acquire such information. What this law provides that is unusual is a prohibition on telling the subjects of search that their records have been turned over to the government. At about 18:00, Litt says,

Despite what you may have heard about this program, we don not collect the content of any communication under this program. We do not collect the identity of any participant to any communication under this program. And while there seems to have been some confusion about this …, I want to make perfectly clear. We do not collect cell phone location information under this program, either GPS or cell site tower information. Not sure why it has been so hard to get people to understand that because it has been said repeatedly.

I speculated a couple of weeks ago that the content of all telephone calls is being recorded, and cited a couple of odd statements that supported my speculation. Litt flatly denies that telephone calls are routinely being recorded. Or does he? He denies, not once, not twice, but three times in three sentences, that various things, including the capture of the content of telephone calls, are being done under this program. Of course that might just be lawyerly conservatism. He can speak only to what he knows about, or only to what he is authorized to speak about, and on this particular occasion that is the two surveillance programs Snowden disclosed. So we really can't conclude anything about the recording of voice conversations, except that if it is being done, it is not being done under this particular program under the authority of Section 215. Moreover, Litt makes clear that (as the statute demands) the data is turned over to the authorities only upon execution of a specific request. "Each determination of a reasonable suspicion under this program," Litt says around 21:00, "must be documented and approved. And only a small portion of the data that is collected is ever actually reviewed, because the vast majority of that data is never going to be responsive to one of these terrorism related queries. In 2012 fewer than 300 identifiers were approved for searching this data." So the government is not entitled to browse willy-nilly across this vast database, and does not do so. And, as Litt states elsewhere in this presentation, it does not do massive data analysis or pattern recognition on the database as a whole. It waits for a specific query to be authorized by the FISA court and then gets just the slice of the metadata-base associated with that identifier. So here is my question. The Fourth Amendment states:

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

It seems that the government's position is that the telephone metadata is neither searched nor seized when it is recorded, only when
