New legal limits on surveillance in the US

The United States has new legal limits on electronic surveillance, both in one specific way and — more important — in prevailing judicial theory. This falls far short of the protections we ultimately need, but it’s a welcome development even so.

The recent Supreme Court case Carpenter v. United States is a big deal. Let me start by saying:

*The Katz test basically says that that an individual’s right to privacy is whatever society regards as a reasonable expectation of privacy at that time.

**The third-party doctrine basically says that any information of yours given voluntarily to a third party isn’t private. This includes transactional information such as purchases or telephone call detail records (CDRs)

Key specifics include:

Also very relevant was the 2012 case requiring warrants for GPS tracking, United States v Jones. But discussion of the Jones decision is confusing, because while some justices at the time addressed the issue of general electronic tracking of a person’s movements, others focused narrowly on the physical action of installing the GPS device.

Unfortunately, all the good news in Carpenter notwithstanding, the decision doesn’t come close to accomplishing as much as we need. I stand by my oft-repeated observations:

  • Massive surveillance is inevitable.
  • Unless the uses of the resulting information are VERY limited, freedoms will be chilled into oblivion.

Justice Roberts correctly wrote in the Carpenter decision:

Mapping a cell phone’s location … provides an intimate window into a person’s life, revealing not only his particular movements, but through them his “familial, political, professional, religious, and sexual associations.”

Justice Kennedy however rejoindered:

What persons purchase and to whom they talk might disclose how much money they make; the political and religious organizations to which they donate; whether they have visited a psychiatrist, plastic surgeon, abortion clinic, or AIDS treatment center; whether they go to gay bars or straight ones; and who are their closest friends and family members.

His point, also correct, was that the data that police are allowed to get without warrants is even more privacy-violating than the data Carpenter keeps away from them. And so, as good as the Carpenter decision apparently is, privacy invasion and surveillance are still among the gravest threats to liberty that we face.

    I am interested in conducting a national representative poll concern public opinion and awareness on privacy awareness / privacy politics / “privacy evasion acceptance”

    I would be willing to provide you data in return for some base input into the questionnaire.
