Proportionality, Privacy, And Public Opinion: A Reply To Kerr And Swire, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In 2007, I published Privacy at Risk: The New Government Surveillance and the Fourth Amendment.' The immediate trigger for the book was the recent upsurge in government use of technology to monitor public and private behavior, and more particularly the tremendous increase in government surveillance after 9/11 using techniques such as data mining, phone and computer intercepts, and public camera systems. The primary analytical target of the book, however, was more general: Supreme Court case law that, read broadly, permits much of this technological surveillance to take place without impinging on any constitutional interests. In an effort to counteract this …

Separated By A Common Language? An Examination Of The Transatlantic Dialogue On Data Privacy Law And Policy In The Fight Against Terrorism, Yesha Yadav

Vanderbilt Law School Faculty Publications

This paper examines recent controversies in the legal and policy debate between the U.S. and the EU on the sharing of data in the implementation of transatlantic counter-terrorism measures. The nexus between law and policy in this area is particularly close, reflecting the preferences each jurisdiction has in protecting civil liberty and security interests. While the U.S. and the EU offer differing legal frameworks on data privacy, the strategic importance of data in counter-terrorism law and policy necessitates a joint approach. A failure to arrive at such an approach can result in a series of bilateral agreements between the U.S. …

Legal Aspects Of Prior Informed Consent On Access To Genetic Resources, Kuei-Jung Ni

Vanderbilt Journal of Transnational Law

Since the Convention on Biological Diversity (CBD) has been in force, national implementation of the access to and benefit-sharing (ABS) requirement on genetic resources has been flourishing. A requirement of prior informed consent (PIC) by the people controlling access to genetic resources constitutes a major instrument to deter illegal bioprospecting and to ensure fair access to genetic resources.

This Article aims to analyze the continuing global lawmaking on PIC and to conduct a comparative study on how genetically rich nations implement the PIC requirement with a view to examining whether the genuine mandate of the CBD has been fulfilled.

This …

Government Data Mining And The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The government's ability to obtain and analyze recorded information about its citizens through the process known as data mining has expanded enormously over the past decade. Although the best-known government data mining operation (Total Information Awareness, more recently dubbed Terrorism Information Awareness) supposedly no longer exists, large-scale data mining by federal agencies devoted to enforcing criminal and counter-terrorism laws has continued unabated. This paper addresses three puzzles about data mining. First, when data mining is undertaken by the government, does it implicate the Fourth Amendment? Second, does the analysis change when data mining is undertaken by private entities which then …

The Liberal Assault On The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

As construed by the Supreme Court, the Fourth Amendment's reasonableness requirement regulates overt, non-regulatory government searches of homes, cars, and personal effects-and virtually nothing else. This essay is primarily about how we got to this point. It is fashionable to place much of the blame for today's law on the Warren Court's adoption of the malleable expectation of privacy concept as the core value protected by the Fourth Amendment. But this diagnosis fails to explain why even the more liberal justices have often gone along with many of the privacy-diminishing holdings of the Court. This essay argues that three other …

Rethinking The Substantive Due Process Right To Privacy: Grounding Privacy In The Fourth Amendment, Mary H. Wimberly

Vanderbilt Law Review

Little in the jurisprudence of the Supreme Court has spurred as much controversy as the Court's recognition of a constitutional right to privacy. While implicitly acknowledging that such a right is not listed in the text of the Constitution, in Griswold v. Connecticut the Court found that the right existed in the "penumbras" of the amendments to the Constitution.' According to the Court, the right to privacy was present in "emanations" from the guarantees of the Bill of Rights. This reasoning was notoriously extended to abortion in Roe v. Wade. In order to invalidate state regulation of abortion, the Roe …

The Revamped Fisa: Striking A Better Balance Between The Government's Need To Protect Itself And The 4th Amendment, J. Christopher Champion

Vanderbilt Law Review

The investigations of the 9/11 terrorist attacks highlighted a series of lapses in intelligence-sharing within the federal government regarding terrorist operations. One area closely examined by Congress,' the judiciary, and many legal and political commentators is the appropriate scope of intelligence collection within the United States "concerning foreign threats to the nation's security" ("foreign intelligence"). Domestic intelligence collection is a particularly complex sphere of national security as gathering intelligence on American soil requires balancing the privacy rights of individuals guaranteed by the Fourth Amendment against the nation's need to protect itself.

The Foreign Intelligence Surveillance Act of 1978 ("FISA") governs …

Transaction Surveillance By The Government, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This symposium article is the second of two on regulation of government efforts to obtain recorded information for criminal prosecutions. More specifically, it explores the scope and regulation of "transaction surveillance," which it defines as government attempts to access already existing records, either physically or through data banks, and government efforts to obtain, in real-time or otherwise, "catalogic data" (the identifying signals of a transaction, such as the address of an email recipient). Transaction surveillance is a potent way of discovering and making inferences about a person's activities, character and identity. Yet, despite a bewildering array of statutorily created authorization …

Reconciling Consent Searches And Fourth Amendment Jurisprudence: Incorporating Privacy Into The Test For Valid Consent Searches, David J. Housholder

Vanderbilt Law Review

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.

Perhaps the most significant exception to the requirements of the Fourth Amendment is the consent search, which requires no warrant, exigent circumstances, probable cause, or reasonable suspicion.

Some scholars have suggested that the Supreme Court's voluntariness standard for determining consensual searches misperceives …

The Unconstitutionality Of "Hold Until Cleared": Reexamining Material Witness Detentions In The Wake Of The September 11th Dragnet, Ricardo J. Bascuas

Vanderbilt Law Review

On March 11, 2004, terrorists affiliated with the Al Qaida networkl detonated bombs on four commuter trains in Madrid, Spain, killing 191 people and injuring 2,000 others. Hours later, the Spanish National Police (SNP) recovered a fingerprint from a bag of detonators found in a stolen van parked at a station from which three of the bombed trains departed. The SNP requested assistance from the United States Federal Bureau of Investigation to identify the owner of the print. FBI experts concluded that the print belonged to Brandon Mayfield, a U.S. citizen living in a suburb of Portland, Oregon, and the …

Applying Pen Register And Trap And Trace Devices To Internet Communications, Rich Haglund

Vanderbilt Journal of Entertainment & Technology Law

This note will explain how the different surveillance methods work: wire taps, pen register and trap and trace devices. It will outline the development of case law and legislation defining what constitutes unlawful searches and seizures involving electronic communications. After explaining how email and internet addresses are collected (and whether the FBI's tool for collection works within the bounds set by the law), this note will discuss the provisions of the Patriot Act that regulate collection of that information. This note will show, using the application of pen register and trap and trace devices to the Internet as an example, …

The Poverty Exception To The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This essay, written for the Sixth Annual LatCrit conference, explores the subterranean motifs of current rules regulating searches and seizures by the police. More specifically, it investigates whether and to what extent alienage, race and poverty influence the warrant and individualized suspicion rules purportedly governing police investigation. The essay begins by showing that, contrary to the assertion of other conference participants, Supreme Court doctrine has not created a "Mexican exception" to the Fourth Amendment (as distinguished from an "illegal alien" exception, which does seem to exist). The main focus of the article, however, is an examination of whether the Court's …

Press One For Warrant: Reinventing The Fourth Amendment's Search Warrant Requirement Through Electronic Procedures, Justin H. Smith

Vanderbilt Law Review

Numerous rulings by the Supreme Court have confirmed the long-held assertion that the Fourth Amendment's warrant requirement is a "centerpiece for the law of search and seizure, and that prescreening by neutral and detached magistrates is [at] the heart of citizens' protection against police overreaching." On September 21, 1994, however, these assertions proved inaccurate and painfully hollow for Betty Ingram, a fifty-three-year-old diabetic who awoke to the sound of armed police officers charging through her front door. The officers, who were searching for a suspect involved in a buy- and-bust operation, had neither obtained a search warrant nor knocked and …

Peeping Techno-Toms And The Fourth Amendment: Seeing Through Kyllo's Rules Governing Technological Surveillance, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article suggests that the Supreme Court's decision in Kyllo v. United States may not be as protective of the home as it first appears. Kyllo held that use of a thermal imager to detect heat sources inside the home is a fourth amendment search, requiring a warrant and probable cause. But it also held that use of technology that is in "general public use" or that only discovers what a naked eye observer could see from a public vantage point is not a search, even when the location viewed is the interior of the home. This article shows that …

An Empirically Based Comparison Of American And European Regulatory Approaches To Police Investigation, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article takes a comparative and empirical look at two of the most significant methods of police investigation: searches for and seizures of tangible evidence and interrogation of suspects. It first compares American doctrine regulating these investigative tools with the analogous rules predominant in Europe (specifically, England, France and Germany). It then discusses research on the American system that sheds light on the relative advantages and disadvantages of the two regulatory systems. More often than not, the existing data call into question preconceived notions of what "works." In particular, American reverence for search warrants, the exclusionary rule, and "Miranda" warnings …

Urine Trouble! Extending Constitutionality To Mandatory Suspicionless Drug Testing Of Students In Extracurricular Activities, James M. Mccray

Vanderbilt Law Review

The United States makes clear its reverence for education by demanding that its children attend school.' What is less clear, how- ever, is the nation's dedication to each student's constitutional rights. From the earliest days of the common law, public school students have lacked fundamental rights, even the right of liberty in its narrowest sense.' Although public students retain certain constitutional rights,' the public school system maintains an elevated power over its students." This power is like that of a parent,' including the duty to "inculcate the habits and manners of civility" into its students.' The public school's control over …

Why Liberals Should Chuck The Exclusionary Rule, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article makes the case against the exclusionary rule from a "liberal" perspective. Moving beyond the inconclusive empirical data on the efficacy of the rule, it uses behavioral and motivational theory to demonstrate why the rule is structurally unable to deter individual police officers from performing most unconstitutional searches and seizures. It also argues, contrary to liberal dogma, that the rule is poor at promoting Fourth Amendment values at the systemic, departmental level. Finally, the article contends that the rule stultifies liberal interpretation of the Fourth Amendment, in large part because of judicial heuristics that grow out of constant exposure …

Let's Not Bury Terry: A Call For Rejuvenation Of The Proportionality Principle, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Thirty years ago, "Terry v. Ohio" established a conceptual framework for the Fourth Amendment that makes more sense than any alternative the courts or commentators have come up with since. That frame-work, which I call the proportionality principle, is very simple: a search or seizure is reasonable if the strength of its justification is roughly proportionate to the level of intrusion associated with the police action. As the Court put it, "there is 'no ready test for determining reasonableness other than by balancing the need to search or seize against the invasion which the search or seizure entails.' In "Terry" …

Race And The Fourth Amendment, Tracey Maclin

Vanderbilt Law Review

In Whren v. United States, the Supreme Court held that pretextual traffic stops do not raise Fourth Amendment concerns. In this Article, Professor Maclin contends that by requiring only probable cause of a traffic offense to justify pretextual seizures, the Court mistakenly ignores racial impact when marking the protective boundaries of the Fourth Amendment. Professor Maclin argues that race matters when measuring the dynamics and legitimacy of certain police-citizen encounters. Pretextual traffic stops unreasonably use racial targeting, therefore, the Court should make racial impact a factor in determining the constitutionality of the pretextual seizure.

Professor Maclin begins by examining objective, …

Technologically-Assisted Physical Surveillance: The American Bar Association's Tentative Draft Standards, Christopher Slobogin

Vanderbilt Law School Faculty Publications

As the name implies, the American Bar Association's Tentative Draft Standards Concerning Technologically-Assisted Physical Surveillance is a work in progress...Final approval by the ABA hierarchy is still some time away, so feedback could have an impact. Indeed, it is anticipated that the content of at least some of the standards will change prior to their submission to the House of Delegates...The work of the Task Force on Technology and Law Enforcement has persuasively demonstrated that some regulatory structure governing the use of physical surveillance technology is necessary. This work provides a model for future attempts to establish guidelines for other …

Having It Both Ways: Proof That The U.S. Supreme Court Is "Unfairly" Prosecution-Oriented, Christopher Slobogin

Vanderbilt Law School Faculty Publications

If the assertions that this essay makes about the Court's "unfair" prosecution-orientation withstand scrutiny," two further conclusions might follow. First, the highest court in the country is so fixated on ensuring that a particular side wins that it is willing with some frequency to sacrifice the most basic attribute of any court worthy of the name-the appearance of fairness. This conclusion is a much more fundamental challenge to the Court's integrity than is the simple acknowledgement that a majority of the Justices are biased in favor of the government. Second, to the extent the Court's unfairness becomes common knowledge, its …

Revoking The "Fishing License:" Recent Decisions Place Unwarranted Restrictions On Administrative Agencies' Power To Subpoena Personal Financial Records, Jack W. Campbell, Iv

Vanderbilt Law Review

The backbone of an administrative agency's effectiveness is the ability to investigate rapidly the activities of entities within the agency's jurisdiction., An agency's ability to carry out its investigative functions depends upon enforcement of the agency's administrative subpoenas. Courts have not always looked favorably upon broad agency subpoena power. The implementation of the New Deal and the exigencies of World War II created a need for increased administrative oversight of national affairs. Courts began to recognize the usefulness of proactive administrative government. Concurrent supreme court decisions reflected this philosophical change by adopting highly deferential views of administrative subpoena enforcement. This …

The Continuing Evolution Of Criminal Constitutional Law In State Courts, S. Carran Daughtrey

Vanderbilt Law Review

Although early state constitutions were important and ambitious documents for their time, the development of state constitutional law stagnated after the drafting and adoption of the federal constitution., As the doctrine of federalism has resurfaced, however, states have begun to turn to their constitutions to grant more protection for their citizens. The states' criminal constitutional laws have changed significantly and continue to evolve today.

In the 1960s, the Warren Court expanded basic protections for criminal defendants by finding that the Fourteenth Amendment incorporates the Fourth, Fifth, and Sixth Amendments. The Court held that the Eighth Amendment prohibits cruel and unusual …

Developing A Meaningful Fourth Amendment Approach To Automobile Investigatory Stops, Andrew J. Pulliam

Vanderbilt Law Review

Police officers throughout the nation face the practical application of Fourth Amendment' protections in the automobile investigatory stop context daily in a wide variety of settings. Nevertheless, the Supreme Court has yet to articulate a functional analytical approach to automobile investigatory stops. This lack of guidance is particularly troublesome when one considers that the Framers specifically designed the Fourth Amendment to prevent government officials from conducting investigations in an oppressive, unreasonable manner. The problem is not simply theoretical but has manifested itself through confusion in the lower courts. The lack of response from the Court on this issue has left …

Toward An International Fourth Amendment: Rethinking Searches And Seizures Abroad After Verdugo-Urquidez, Eric Bentley, Jr.

Vanderbilt Journal of Transnational Law

Should the Fourth Amendment reach abroad to protect noncitizens when United States law enforcement agents conduct searches and seizures in a foreign state? The courts have assumed this to be a closed question since 1990, when the Supreme Court, in a broadly worded plurality opinion by Chief Justice Rehnquist, asserted that the Amendment protects only citizens and other members of the "national community." However, as this Article points out, the Chief Justice's plurality opinion in United States v. Verdugo-Urquidez did not represent the judgment of a majority of the Court and therefore does not foreclose continued consideration of the scope …

Reasonable Expectations Of Privacy And Autonomy In Fourth Amendment Cases: An Empirical Look At "Understandings Recognized And Permitted By Society", Christopher Slobogin, Joseph E. Schumacher

Vanderbilt Law School Faculty Publications

This Article reports an attempt to investigate empirically important aspects of the Fourth Amendment to the United States Constitution, as construed by the United States Supreme Court. In the course of doing so, it touches upon two other topics. Most directly, it addresses the appropriate scope of the Fourth Amendment. Less directly, it raises questions about the role that empirical research should play in fashioning constitutional rules.

Anticipatory Search Warrants: The Supreme Court's Opportunity To Reexamine The Framework Of The Fourth Amendment, David P. Mitchell

Vanderbilt Law Review

The Fourth Amendment to the United States Constitution prohibits "unreasonable searches and seizures," and provides that "no War-rants shall issue, but upon probable cause."' Although its language is relatively clear, the application of the Fourth Amendment has created more controversy than the application of perhaps any other constitutional amendment.' Given the questions raised by a police-endorsed practice of anticipatory search warrants,' the search and seizure debate is far from over.

An anticipatory search warrant is a warrant based on a showing of probable cause that particular evidence of a crime will exist at a specific location in the future. Challenges …

Tapping The State Court Resource, Ann Althouse

Vanderbilt Law Review

Supreme Court opinions about federal jurisdiction usually feature painstaking analysis of the text of statutes and constitutional clauses and the intentions of those who authored them, or they are based on long-standing traditions of equity jurisprudence. But, as the Court's many divided decisions attest, these materials are scarcely clear enough to determine all outcomes. Thus, the Justices often seem to weigh various interests when they draw the lines around federal jurisdiction. The Court sometimes openly acknowledges this interest weighing, referring to "state interests" and "federal interests."

Justice Stevens has taken exception to this process. He has ob- served that much …

The World Without A Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The subject of this Article is suggested by a single question: How would we regulate searches and seizures if the Fourth Amendment did not exist? This question is a useful one to ask even leaving aside the possibility of amending the amendment. Starting on a blank slate, as it were, should free us from current preconceptions about the law of search and seizure, ingrained after years of analyzing current dogma. Viewed from this fresh perspective, we might gain a better understanding of the values at stake when the state seeks to obtain evidence or detain suspects. This new understanding in …

Reworking The Warrant Requirement: Resuscitating The Fourth Amendment, Phyllis T. Bookspan

Vanderbilt Law Review

Ninety-three years ago, in response to a newspaper account, Mark Twain wrote: "The reports of my death are greatly exaggerated." While it may be premature to sound the death knell for the fourth amendment, it is no exaggeration to suggest that unless drastic action is taken to remedy the destructive erosion of the fourth amendment, it may as well be buried.

Current search and seizure doctrine is inconsistent and incoherent.' No one, including the police who are to abide by it, judges who apply it, or the people who are protected by it, has any meaningful sense of what the …
