(Big) Exceptions to Restrictions on Domestic Surveillance


“Nobody is listening to your telephone calls,” Mr. Obama said when the news broke.
But as experts on American intelligence knew, that was not the whole story. It left out what N.S.A. officials have long called “incidental” collection of Americans’ calls and e-mails — the routine capture of Americans’ communications in the process of targeting foreign communications.

The Reliability or Unreliability of Our Always-Constructed Memories


It is generally believed -- and I believe -- that the mind does not work like a tape recorder and that memories are "constructed."

Does it follow that all memories -- which are constructed, or assembled, by the mind -- are unreliable?

No: that proposition does not logically follow. It is possible that some constructed memories -- i.e., some mental or neural inferential processes -- are reliable.
  • Anecdote: I am quite sure I correctly remember what my sister looks like. The same holds true for my memory of upstairs neighbors, my daughter, etc.
If our memories were systematically "unreliable," most people would get lost on their way to work, on their way home, etc. We generally remember many things correctly.

Of course, some memories -- e.g., very old ones, our memories of people seen only once, etc. -- are very probably substantially less trustworthy than many other memories.
  • Even here, caution must be exercised. For example, unconscious recall may (sometimes) be more reliable than conscious recall.

Conscious Memories Are Constructed

Christopher D. Frith, "Disorders of Conscious and Unconscious Mental Processes," in Eric R. Kandel, James H. Schwartz, Thomas M. Jessel, Steven A. Siegelbaum & A. J. Hudspeth, eds., Principles of Neural Science 1373, 1383 (5th ed., 2013):
[M]emory is a creative process. Our conscious memories are constructed from both conscious recall and unconscious knowledge.

Therefore?

Vision and Inference


Charles D. Gilbert, "The Constructive Nature of Visual Processing," in Eric R. Kandel, James H. Schwartz, Thomas M. Jessel, Steven A. Siegelbaum & A. J. Hudspeth, eds., Principles of Neural Science 556, 556-557 (5th ed., 2013):

Vision is often incorrectly compared to the operations of a camera. Unlike a camera, however, the visual system is able to create a three-dimensional representation of the world from the two-dimensional images on the retina. In addition, an object is perceived as the same under strikingly different visual conditions.

A camera reproduces point-by-point the light intensities in one plane of the visual field. The brain, in contrast, parses scenes into distinct components, separating foreground from background, to determine which light stimuli belong to one object and which to others. In doing so it uses previously learned rules about the structure of the world. In analyzing the incoming scream of visual signals the brain guesses at the scene presented to the eyes based on past experience.

This constructive nature of visual perception has only recently been fully appreciated. Earlier thinking about sensory perception was greatly influenced by the British empiricism philosophers, notably John Locke, David Hume, and George Berkeley, who thought of perception as an atomistic process in which simple sensory elements, such as color, shape, and brightness, were assembled in an additive way, component by component. The modern view that perception is an active and creative process that involves more than just the information provided by the retina has its roots in the philosophy of Immanuel Kent and was developed in detail in the early 20th century by the German psychologists Max Wertheimer, Kurt Koffka, and Wolfgang Koehler, who founded the school of Gestalt psychology.

The German term Gestalt means configuration or form. The central idea of the Gestalt psychologists is that what we see about a stimulus--the perceptual interpretation we make of any visual object--depends not just on the properties of the stimulus but also on its context, on other features in the visual field. The Gestalt psychologists argued that the visual system processes sensory information about the shape, color, distance, and movement of objects according to computational rules inherent in the system. The brain has a way of looking at the world, a set of expectations that the rides in part from experience and in part from built-in neural wiring.

The Scientific Origins of the Polygraph Test

Sally Satel & Scott O. Lillienfeld, BRAINWASHED: THE SEDUCTIVE APPEAL OF MINDLESS NEUROSCIENCE 78 (Basic Books, 2013) (footnotes omitted):
In the early 1900s, William Moulton Marston, an undergraduate at Harvard, invented the precursor of the modern polygraph. The device recorded breathing rate by means of a pneumatic rubber hose wrapped around the subject's chest and a blood-pressure cuff encircling the upper arm. In a charming footnote to polygraph history, Marston later became a comic-book writer and, under the pen name of Charles Moulton, created Wonder Woman, an action heroine who wore a a "Golden Lasso of Truth" around her waist. When villains were lassoed with her magical version of the pneumatic hose, they were forced to tell the truth.
This history (or "prehistory") makes me Wonder how the polygraph test ever escaped universal ridicule.

Update: How to download my evidence marshaling software (MarshalPlan)

A. Background

Years ago David A. Schum and I developed the notion of an evidence marshaling system. We laid out the underlying theory of this evidence marshaling system in A Theory of Preliminary Fact Investigation. We developed a kind of computer embodiment, or computer-based expression, of our idea of an evidence marshaling system. Eventually we decided to call our system "MarshalPlan."


  • Some of my more recent thoughts about the theoretical foundations of MarshalPlan may be found here (long blog post called "The Ramshackle -- and Logical -- Character of Explicit Human Factual Inference" (June 18, 2011)).
  • In the years following my seven(!)-year NSF-supported collaboration with David Schum, I continued to tinker with MarshalPlan. I did so by both modifying and adding "stacks," or files. (Each stack corresponds to an evidence marshaling strategy, or method.) The most recent iteration of the evidence marshaling software is MarshalPlan 5.5.

    A few years ago  I began to make MarshalPlan available via the internet.  However, since I am not a programmer and since I lack many basic computer skills, I have not managed to devise a single method of accessing or download in MarshalPlan 5.5 that works for everyone. This is why I lay out two or more ways for you to download MarshalPlan. One of these downloading methods should work for you.



    B. Caveats

    Before you download or access MarshalPlan, however, please consider the following important caveats:
    1. The current iteration of MarshalPlan -- MarshalPlan 5.5 -- is not a prototype of a working application suitable for real-time and real-world use. Far from it! However, MarshalPlan 5.5 goes beyond just scratchings (text) that explain how an evidence marshaling application might work. Even so, it is not far from the truth to say that MarshalPlan is mainly an elaborate visual illustration of some of the directions that development of software for marshaling evidence in legal settings should take. But, but ... MarshalPlan 5.5 is a bit more than an illustration of possible future directions for research and development. MarshalPlan as it now stands is useful for pedagogical (i.e., teaching) purposes. Moreover, MarshalPlan is creeping ever closer to being something akin to a genuine software prototype suitable for real-world and real-time use. 
    2. In MarshalPlan 5.5 there are only brief explanations of some of the evidence marshaling strategies found there. Other marshaling strategies, however, are described and explained more fully. For a comprehensive account of the thinking that went into MarshalPlan, please see the readings mentioned above. If you want a truly comprehensive theory-laden explanation of MarshalPlan, you will have to invite me to give a leisurely talk (preferably on a tropical island or some other attractive venue).
    3. A few buttons and links may not work. If that happens, try other buttons and links. (Otherwise resort to expletives. You have my permission.) 
    4. MarshalPlan 5.5 is not set up to be linked to a database. This is a most serious deficiency for any possible real-world use in a context such as law practice.

    C. Instructions

    Try one or more of the following methods to view and play with MarshalPlan 5.5:
    1. MarshalPlan on the web: If you use the now-ancient Firefox 3.x and you are willing to accept a plug-in, you may be able to view MarshalPlan 4.0 in your (Firefox) browser. To try this, click this link.
    2. You can download MarshalPlan 5.5 for use on a Windows computer by  going to http://tillers.net/MarshalPlan.5.5/ and opening the subfolder "Windows" and then clicking on MarshalPlan 5.5exe.


    • Postscript, 2013.10.04: A free open source version of the scripting language for MarshalPlan is now available here; it is called "LiveCode Community."


    • Caveat: I reserve my copyright to MarshalPlan. This means in part that you cannot distribute, lease, or use any version of MarshalPlan for profit or for commercial purposes without my express written permission.
    3. As of 6/11/2013,  you will very probably not be able to run the MarshalPlan 5.5 downloaded in this way (see par. 2 above) on an Apple computer. The Apple OS probably still strips a thus-downloaded MarshalPlan of the ability to run on Apple computers. Sorry! {Take your grievance if any to the paternalistic Apple Corporation, which likes closed worlds, particularly those that it controls.} But there is a solution! Send an email message to peter@tillers.net and ask me to share a relevant DropBox folder with you. I will happily oblige.

    Jack Shafer on Government Collection of Reams of Personal Data


    Jack Shafer, The spy who came in for your soul Reuters (June 8, 2013):

    Snippet:

    "Faster than you can say evaporation-condensation-precipitation, I expect this week’s exposés to produce additional investigations that will produce more leaks and further scoops about our digital records. This will now fuel new cycles of reporting, leaks and scoops — and another, and another — as new sources are cultivated and reportorial scraps gathering mold in journalists’ notebooks gain new relevance and help break stories.


    "Greenwald’s storm will continue to rage because, I suspect, the story won’t be limited to just phone records or Web data. Ultimately, it will be about the government’s pursuit of all the digital breadcrumbs we produce as necessary byproducts of day-to-day life — and phone records and Web data are just a small part.

    "Bank records, credit history, travel records, credit card records, EZPass data, GPS phone data, license-plate reader databases, Social Security and Internal Revenue Service records, facial-recognition databases at the Department of Motor Vehicles and elsewhere, even 7-Eleven surveillance videos comprise information lodes that are of equal or greater value to the national security establishment than phone and Web files. It doesn’t sound paranoid to conclude that the government has reused, or will reuse, the interpretation of the Patriot Act it presented to the secret FISA court in its phone record and Prism data requests to grab these other data troves.

    "Lest I sound like a Fourth Amendment hysteric, I understand there’s nothing automatically sacrosanct about any of the digital trails we leave behind. Lawful subpoenas can liberate all sorts records about you, electronic or otherwise.

    "What’s breathtaking about these two government surveillance programs that the Guardian and theWashington Post have revealed is that they’re vast collections of data about hundreds of millions of people suspected of no wrongdoing and not part of any civil action. Defending the phone-record cull, National Intelligence Director James R. Clapper explained this week that smaller sets of information aren’t very useful in screening for and identifying “terrorism-related communications,” hence all must collected."

    Excellent Op-Ed by Gail Collins on NSA Spying and Obama


    Gail Collins,  Intelligence for Dummies NYTimes (June 7, 2013).

    Snippets (but do read the entire op-ed column):

    "'Nobody is listening to your telephone calls,' President Obama assured the American people on Friday. Well, probably nobody. And, if they are, it’s under an entirely different part of the program.

    ...

    "Let’s start with the real basics. Does the N.S.A. really need all the stuff it’s collecting? Ever since the attack on the World Trade Center, the agency has been exploding. It has an enormous operation outside of Washington, and it is building another million-square-foot complex in the Utah desert. It collects an estimated 1.7 billion pieces of communication a day. 'When you have the ability to get more and more data, the natural inclination is to get as much as possible,' said Representative Henry Waxman, the former chairman of the House oversight committee.
    ...
    "...[W] e do seem to have an ominous combination: an agency with a bad record on thriftiness, and practically everything it spends money on is secret. 'It’s a tough balancing act,' an Obama administration official told me. 'It’s incumbent on us and Congress to do the job of scrutinizing the budget, both in terms of cost and efficacy.'
    "Yeah, what about Congress? The president keeps saying that “Congress is continually briefed” about security issues. In reality, the briefing is pretty much confined to the members of the House and Senate intelligence committees, who are sworn to secrecy. Many of them also have a longstanding record of being in the pocket of the intelligence community. A few of the others had been desperately trying to warn their colleagues about the telephone-call program without breaking their vow of silence. Senator Ron Wyden of Oregon did everything but tap dance the information in Morse code.
    ...
    "I wouldn’t rely on Congress to keep things under control. It’s really up to the president. As a candidate, Obama looked as if he would be great at riding herd on the N.S.A.’s excesses. But if he has ever seriously pushed back on the spy set, it’s been kept a secret. Meanwhile, the administration scarfs up reporters’ e-mails and phone records in its obsessive war against leaks.
    ...
    "“I welcome this debate,” Obama said Friday. “I think it’s healthy for our democracy.” Under further questioning, he said that he definitely didn’t welcome the leaks. Without which, of course, there would be no debate.
    "Do you remember how enthusiastic people were about having a president who once taught constitutional law? I guess we’ve learned a lesson."

    How PRISM May Work

    N.B. ZDNet astutely noticed that President Obama parsed his words very carefully on June 7 when denying that NSA's surveillance programs are unduly intrusive.

    America, the Surveillance State


    Dan Roberts & Spencer Ackerman, America's surveillance state: anger swells after data revelations The Guardian (online) (June 6, 2013).

    Snippets:

    "The scale of America's surveillance state was laid bare on Wednesday as senior politicians revealed that the US counter-terrorism effort had swept up swaths of personal data from the phone calls of millions of citizens for years.

    "After the revelation by the Guardian of a sweeping secret court order that authorised the FBI to seize all call records from a subsidiary of Verizon, the Obama administration sought to defuse mounting anger over what critics described as the broadest surveillance ruling ever issued.

    ...

    "Intelligence committee member Mark Udall, who has previously warned in broad terms about the scale of government snooping, said: "This sort of widescale surveillance should concern all of us and is the kind of government overreach I've said Americans would find shocking." Former vice-president Al Gore described the "secret blanket surveillance" as "obscenely outrageous".

    "The Verizon order was made under the provisions of the Foreign Intelligence Surveillance Act (Fisa) as amended by the Patriot Act of 2001, passed in the wake of the 9/11 attacks. But one of the authors of the Patriot Act, Republican congressman Jim Sensenbrenner, said he was troubled by the Guardian revelations. He said that he had written to the attorney general, Eric Holder, questioning whether 'US constitutional rights were secure'.

    "He said: 'I do not believe the broadly drafted Fisa order is consistent with the requirements of the Patriot Act. Seizing phone records of millions of innocent people is excessive and un-American.'...


    "[White House spokesman Josh Earnest said] the [FISA] order only relates to the so-called metadata surrounding phone calls rather than the content of the calls themselves. 'The order reprinted overnight does not allow the government to listen in on anyone's telephone calls,' Earnest said.

    "'The information acquired does not include the content of any communications or the name of any subscriber. It relates exclusively to call details, such as a telephone number or the length of a telephone call.'

    "But such metadata can provide authorities with vast knowledge about a caller's identity. Particularly when cross-checked against other public records, the metadata can reveal someone's name, address, driver's licence, credit history, social security number and more. Government analysts would be able to work out whether the relationship between two people was ongoing, occasional or a one-off."

    &&&


    Charles Savage & Edward Wyatt, U.S. Maintains Vast Database of Phone Calls, Lawmakers Say, NYTimes (June 6, 2013):

    "As the scope of the government’s collection of logs of Americans’ domestic communications started to come into greater focus on Thursday, privacy groups erupted. Anthony Romero of the American Civil Liberties Union said that group — a client of Verizon’s business unit — was considering filing a lawsuit to challenge the 'dragnet' surveillance, and said liberals would be furious had such a program been disclosed under a Republican administration.

    "'A pox on all the three houses of government,' he said. 'On Congress, for legislating such powers, on the FISA court for being such a paper tiger and rubber stamp, and on the Obama administration for not being true to its values.

    The Case of the Angel of Death


    Duncan Campbell, Fresh evidence challenges 'Angel of Death' nurse Colin Norris's conviction, Guardian (May 20, 2013):

    "Fresh medical and scientific evidence is being published this week that campaigners hope will lead to the release of Colin Norris, the former nurse and so-called 'Angel of Death' serving life for the murder or attempted murder of five elderly women.

    "The Criminal Cases Review Commission (CCRC) has confirmed it is undertaking an active re-examination of the case.

    "Norris, 37, originally from Glasgow, was convicted at Newcastle crown court in 2008 following a 19-week trial. It was alleged that he disliked elderly patients and had deliberately injected the women with insulin. The case had echoes of the late Dr Harold Shipman, who was convicted of murdering 15 of his patients but believed to have killed many more.

    "However, a new study challenges much of the evidence on which Norris was convicted. Campaigners are hopeful that fresh evidence will lead to an appeal in which it can be shown that the women could have died of natural causes."

    Letting Go (of Books etc.)

    Stanley Fish, Moving On, NYTimes (May 27, 2013):

    Snippets:

    "I have sold my books. Not all of them, but most of them. I held on to the books I might need while putting the finishing touches on a manuscript that is now with my publisher. I also kept the books I will likely need when I begin my next project in the fall. But the books that sustained my professional life for 50 years ... are gone.

     ...

    "The ostensible reason for this de-acquisition is a move from a fair-sized house to a much smaller apartment. It is true, as Anthony Powell said in a title, that books do furnish a room, but in this case, too many books, too little room. But the deeper reason is that it was time. What I saw on the shelves was work to which I would never return....

    "... I had always thought that I could return to my annotated copies of familiar texts and pick up where I left off. That fantasy, I now see, was part and parcel of the core fantasy that I would just go on forever, defending old positions, formulating new ones, attending annual conferences, contributing to essay collections, speaking at various universities, teaching the same old courses, confidently answering the same old questions.

    "I’m not going to go on forever. ...

    "... Behind these musings is a word I can barely utter — 'retirement.' ..."

    &&&

    I recently retired from full-time teaching - but not from writing. So I threw away some of my books, but not most of them. In any event, quite a few of my books are for purely personal pleasure and are still unread. So I can't throw those away, can I?
    • Addendum: Some of my "academic" interests survive my retirement; some of the questions I ask myself genuinely interest (and preoccupy) me.
