Privacy Law: ‘Mosaic Theory’ and Megan’s Laws by Wayne A. Logan, Florida State University College of Law in Cardozo Law Review de novo, p. 95 (2011)
Abstract:
This essay urges reexamination of the privacy implications of registration and community notification (RCN) laws, commonly known as Megan’s Laws. Applying the analytic construct recently employed by the D.C. Circuit in United States v. Maynard to conclude that extended use of a GPS tracking device constitutes a search for Fourth Amendment purposes, the essay argues that the collection and aggregation of registrant data entailed in RCN implicates a protectable Fourteenth Amendment privacy interest. In both contexts, the government collects nominally public data – in Maynard, car travel, with RCN, registrants’ home/work/school addresses, physical traits, etc. – and creates an informational “mosaic” of personal life that would not otherwise practically exist.
With the Supreme Court’s recent grant of certiorari in Maynard (docketed sub nom. United States v. Jones), mosaic theory will soon be the subject of considerable debate. The essay seeks to contribute to this debate, pushing the applicable bounds of the theory and allowing for a more robust examination of RCN, as well as similar data-based social control strategies likely to emerge in coming years.

"It is a pleasant world we live in, sir, a very pleasant world. There are bad people in it, Mr. Richard, but if there were no bad people, there would be no good lawyers."

"A system of law that not only makes certain conduct criminal, but also lays down rules for the conduct of the authorities, often becomes complex in its application to individual cases, and will from time to time produce imperfect results, especially if one's attention is confined to the particular case at bar. Some criminals do go free because of the necessity of keeping government and its servants in their place. That is one of the costs of having and enforcing a Bill of Rights. This country is built on the assumption that the cost is worth paying, and that in the long run we are all both freer and safer if the Constitution is strictly enforced." —Williams v. Nix, 700 F. 2d 1164, 1173 (8th Cir. 1983) (Richard Sheppard Arnold, J.), rev'd Nix v. Williams, 467 US. 431 (1984).
"The criminal goes free, if he must, but it is the law that sets him free. Nothing can destroy a government more quickly than its failure to observe its own laws, or worse, its disregard of the charter of its own existence." —Mapp v. Ohio, 367 U.S. 643, 659 (1961).
"Any costs the exclusionary rule are costs imposed directly by the Fourth Amendment."

"There have been powerful hydraulic pressures throughout our history that bear heavily on the Court to water down constitutional guarantees and give the police the upper hand. That hydraulic pressure has probably never been greater than it is today." — Terry v. Ohio, 392 U.S. 1, 39 (1968) (Douglas, J., dissenting).
"The great end, for which men entered into society, was to secure their property." —Entick v. Carrington, 19 How.St.Tr. 1029, 1066, 95 Eng. Rep. 807 (C.P. 1765)
"It is a fair summary of history to say that the safeguards of liberty have frequently been forged in controversies involving not very nice people. And so, while we are concerned here with a shabby defrauder, we must deal with his case in the context of what are really the great themes expressed by the Fourth Amendment." —United States v. Rabinowitz, 339 U.S. 56, 69 (1950) (Frankfurter, J., dissenting)
"The course of true law pertaining to searches and seizures, as enunciated here, has not–to put it mildly–run smooth." —Chapman v. United States, 365 U.S. 610, 618 (1961) (Frankfurter, J., concurring).
"A search is a search, even if it happens to disclose nothing but the bottom of a turntable." —Arizona v. Hicks, 480 U.S. 321, 325 (1987)
"For the Fourth Amendment protects people, not places. What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection. ... But what he seeks to preserve as private, even in an area accessible to the public, may be constitutionally protected." —Katz v. United States, 389 U.S. 347, 351 (1967)
“Experience should teach us to be most on guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” —United States v. Olmstead, 277 U.S. 438, 479 (1925) (Brandeis, J., dissenting)
“Liberty—the freedom from unwarranted intrusion by government—is as easily lost through insistent nibbles by government officials who seek to do their jobs too well as by those whose purpose it is to oppress; the piranha can be as deadly as the shark.” —United States v. $124,570, 873 F.2d 1240, 1246 (9th Cir. 1989)

"In Germany, they first came for the communists, and I didn't speak up because I wasn't a communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist. Then they came for the Catholics and I didn't speak up because I wasn't a Catholic. Then they came for me–and by that time there was nobody left to speak up."
—Martin Niemöller (1945) [he served seven years in a concentration camp]
“Children grow up thinking the adult world is ordered, rational, fit for purpose. It’s crap. Becoming a man is realising that it’s all rotten. Realising how to celebrate that rottenness, that’s freedom.” – John le Carré, The Night Manager (1993), line by Richard Roper
"The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime." —Johnson v. United States, 333 U.S. 10, 13-14 (1948)
The book was dedicated in the first (1982) and sixth (2025) editions to Justin William Hall (1975-2025). He was three when this project started in 1978.
