Student Surveillance, Racial Inequalities, And Implicit Racial Bias, Jason P. Nance Apr 2019

Student Surveillance, Racial Inequalities, And Implicit Racial Bias, Jason P. Nance

Jason P. Nance

In the wake of high-profile incidents of school violence, school officials have increased their reliance on a host of surveillance measures to maintain order and control in their schools. Paradoxically, such practices can foster hostile environments that may lead to even more disorder and dysfunction. These practices may also contribute to the so-called “school-to-prison pipeline” by pushing more students out of school and into the juvenile justice system. However, not all students experience the same level of surveillance. This Article presents data on school surveillance practices, including an original empirical analysis of restricted data recently released by the U.S. Department …


K-9 Catch-22: The Impossible Dilemma Of Using Police Dogs In Apprehension Of Suspects, Ann L. Schiavone Sep 2018

K-9 Catch-22: The Impossible Dilemma Of Using Police Dogs In Apprehension Of Suspects, Ann L. Schiavone

Ann Schiavone

In the past several years, the city of Pittsburgh, Pennsylvania has seen two canine police dogs (K-9s) killed in the line of duty, Rocco in January 2014, and Aren in January of 2016.  Both were killed by stab wounds while attempting to apprehend suspects. The man who killed Rocco received significant jail for stabbing and killing the dog, while the man who killed Aren was fatally shot as a direct result of his actions toward the canine. While Rocco was vocally celebrated in the community, and sympathy primarily focused on the canine, the deaths of Aren and the suspect who …

Self Incrimination And Cryptographic Keys, Gregory S. Sergienko Mar 2018

Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

Fourth Amendment Anxiety, Stephen E. Henderson, Kiel Brennan-Marquez Dec 2017

Fourth Amendment Anxiety, Stephen E. Henderson, Kiel Brennan-Marquez

Stephen E Henderson

In Birchfield v. North Dakota (2016), the Supreme Court broke new Fourth Amendment ground by establishing that law enforcement’s collection of information can be cause for “anxiety,” meriting constitutional protection, even if subsequent uses of the information are tightly restricted.  This change is significant.  While the Court has long recognized the reality that police cannot always be trusted to follow constitutional rules, Birchfield changes how that concern is implemented in Fourth Amendment law, and importantly, in a manner that acknowledges the new realities of data-driven policing.
 
Beyond offering a careful reading of Birchfield, this Article has two goals. …


Keeping The Government's Hands Off Our Bodies: Mapping A Feminist Legal Theory Approach To Privacy In Cross-Gender Prison Searches, Teresa A. Miller Nov 2017

Keeping The Government's Hands Off Our Bodies: Mapping A Feminist Legal Theory Approach To Privacy In Cross-Gender Prison Searches, Teresa A. Miller

Teresa A. Miller

The power of privacy is diminishing in the prison setting, and yet privacy is the legal theory prisoners rely upon most to resist searches by correctional officers. Incarcerated women in particular rely upon privacy to shield them from the kind of physical contact that male guards have been known to abuse. The kind of privacy that protects prisoners from searches by guards of the opposite sex derives from several sources, depending on the factual circumstances. Although some form of bodily privacy is embodied in the First, Fourth, Eighth, and Fourteenth Amendments, prisoners challenging the constitutionality of cross-gender searches most commonly …


Sex & Surveillance: Gender, Privacy & The Sexualization Of Power In Prison, Teresa A. Miller Nov 2017

Sex & Surveillance: Gender, Privacy & The Sexualization Of Power In Prison, Teresa A. Miller

Teresa A. Miller

In prison, surveillance is power and power is sexualized. Sex and surveillance, therefore, are profoundly linked. Whereas numerous penal scholars from Bentham to Foucault have theorized the force inherent in the visual monitoring of prisoners, the sexualization of power and the relationship between sex and surveillance is more academically obscure. This article criticizes the failure of federal courts to consider the strong and complex relationship between sex and surveillance in analyzing the constitutionality of prison searches, specifically, cross-gender searches. The analysis proceeds in four parts. Part One introduces the issues posed by sex and surveillance. Part Two describes the sexually …

Rethinking The Fourth Amendment In The Age Of Supercomputers, Artificial Intelligence, And Robots, Melanie M. Reid Dec 2016

Rethinking The Fourth Amendment In The Age Of Supercomputers, Artificial Intelligence, And Robots, Melanie M. Reid

Melanie M. Reid

Law enforcement currently uses cognitive computers to conduct predictive and content analytics and manage information contained in large police data files. These big data analytics and insight capabilities are more effective than using traditional investigative tools and save law enforcement time and a significant amount of financial and personnel resources. It is not farfetched to think law enforcement’s use of cognitive computing will extend to using thinking, real-time robots in the field in the not-so-distant future. IBM’s Watson currently uses its artificial intelligence to suggest medical diagnoses and treatment in the healthcare industry and assists the finance industry in improving …


Fourth Amendment Remedies As Rights: The Warrant Requirement, David Gray Apr 2016

Fourth Amendment Remedies As Rights: The Warrant Requirement, David Gray

David C. Gray

The constitutional status of the warrant requirement is hotly debated. Critics argue that neither the text nor history of the Fourth Amendment support a warrant requirement. Also questioned is the warrant requirement’s ability to protect Fourth Amendment interests. Perhaps in response to these concerns, the Court has steadily degraded the warrant requirement through a series of widening exceptions. The result is an unsatisfying jurisprudence that fails on both conceptual and practical grounds.

These debates have gained new salience with the emergence of modern surveillance technologies such as stingrays, GPS tracking, drones, and Big Data. Although a majority of the Court …


On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye Mar 2016

On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye

David Kaye

For nearly a decade, DNA-on-arrest laws eluded scrutiny in the courts. For another five years, they withstood a gathering storm of constitutional challenges. In Maryland v. King, however, Maryland's highest court reasoned that usually fingerprints provide everything police need to establish the true identity of an individual before trial and that the state's interest in finding the perpetrators of crimes by trawling databases of DNA profiles is too "generalized" to support "a warrantless, suspicionless search." The U.S. Supreme Court reacted forcefully. Chief Justice Roberts stayed the Maryland judgment, writing that "given the considered analysis of courts on the other side …


Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye Mar 2016

Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye

David Kaye

In Maryland v. King, the Supreme Court applied a balancing test to uphold a Maryland statute mandating preconviction collection and analysis of DNA from individuals charged with certain crimes. The DNA profiles are limited to an inherited set of DNA sequences that are not known to be functional and that are tokens of individual identity. This invited online essay examines two aspects of an article on the case by Professor Erin Murphy. I question the claim that the case is pivotal in a conceivable abandonment of the per se rule that warrantless, suspicionless searches are unconstitutional unless they fall …


Drawing Lines: Unrelated Probable Cause As A Prerequisite To Early Dna Collection, David H. Kaye Mar 2016

Drawing Lines: Unrelated Probable Cause As A Prerequisite To Early Dna Collection, David H. Kaye

David Kaye

Swabbing the inside of a cheek has become part of the custodial arrest process in many jurisdictions. The majority view (thus far) is that routinely collecting DNA before conviction (and analyzing it, recording the results, and comparing them to DNA profiles from crime-scene databases) is consistent with Fourth Amendment protections against unreasonable searches and seizures. However, some judges and commentators have argued that DNA sampling in advance of a determination by a judge or grand jury of probable cause for the arrest or charge is unconstitutional. This essay shows that this demand is largely unfounded. Either warrantless, suspicionless DNA collection …


Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried Mar 2016

Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

David Kaye

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic area …


Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith Mar 2016

Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith

David Kaye

Over the past decade, law enforcement authorities have amassed huge collections of DNA samples and the identifying profiles derived from them. Large DNA databanks routinely help to identify the guilty and to exonerate the innocent, but as the databanks grow, so do fears about civil liberties. Perhaps the most controversial policy issue in the creation of these databases is the question of coverage: Whose DNA profiles should be stored in them? The possibilities extend from convicted violent sex offenders to all convicted felons, to everyone arrested, to the entire population. This Article questions the rationales for drawing the line at …


The Supreme Court's Quiet Expansion Of Qualified Immunity, Kit Kinports Feb 2016

The Supreme Court's Quiet Expansion Of Qualified Immunity, Kit Kinports

Kit Kinports

This Essay discusses the Supreme Court’s tendency in recent opinions to covertly expand the reach of the qualified immunity defense available to public officials in § 1983 civil rights suits. In particular, the Essay points out that the Court, often in per curiam rulings, has described qualified immunity in increasingly broad terms and has qualified and retreated from its precedents, without offering any explanation or even acknowledging that it is deviating from past practice.In making this claim, I focus on three specific issues: the manner in which the Court characterizes the standard governing the qualified immunity defense; the question whether …


Small Data Surveillance V. Big Data Cybersurveillance, Margaret Hu Feb 2016

Small Data Surveillance V. Big Data Cybersurveillance, Margaret Hu

Margaret Hu

This Article highlights some of the critical distinctions between small data surveillance and big data cybersurveillance as methods of intelligence gathering. Specifically, in the intelligence context, it appears that “collect-it-all” tools in a big data world can now potentially facilitate the construction, by the intelligence community, of other individuals' digital avatars. The digital avatar can be understood as a virtual representation of our digital selves and may serve as a potential proxy for an actual person. This construction may be enabled through processes such as the data fusion of biometric and biographic data, or the digital data fusion of the …


Video Evidence And Summary Judgment: The Procedure Of Scott V. Harris, Howard Wasserman Feb 2016

Video Evidence And Summary Judgment: The Procedure Of Scott V. Harris, Howard Wasserman

Howard M Wasserman

In Scott v. Harris (2007), the Supreme Court granted summary judgment on a Fourth Amendment excessive-force claim brought by a motorist injured when a pursuing law-enforcement officer terminated a high-speed pursuit by bumping the plaintiff's car. The Court relied almost exclusively on a video of the chase captured from the officer's dash-mounted camera and disregarded witness testimony that contradicted the video. In granting summary judgment in this circumstance, the Court fell sway to the myth of video evidence as able to speak for itself, as an objective, unambiguous, and singularly accurate depiction of real-world events, not subject to any interpretation …


Trespass And Deception, Laurent Sacharoff Dec 2015

Trespass And Deception, Laurent Sacharoff

Laurent Sacharoff

Police routinely use deception to get into people’s homes without warrant or probable cause. They may pose as UPS delivery persons or homebuyers, or they may say they are looking for a kidnapping victim or a pedophile, when really they are looking for drugs or guns. Recent years have brought hundreds of reported decisions concerning such police ruses.

When the police lie about their identity or their purpose to enter a home, as when they pose as a homebuyer, the courts surprisingly, but routinely, approve these deceptions under the Fourth Amendment. Such intrusions, the courts reason, do not violate a …


Dangerous Dicta, David Gray Oct 2015

Dangerous Dicta, David Gray

David C. Gray

In United States v. Heller, the Court held that individuals have a Second Amendment right to keep and bear arms apart from their associations with state militias. Although that holding was and remains controversial, less attention has been paid to what the Heller Court had to say about the Fourth Amendment. Writing for the Court in Heller, Justice Scalia asserts that the phrase “right of the people” in the Fourth Amendment “unambiguously refers to individual rights, not ‘collective’ rights or rights that may only be exercised through participation in some corporate body.” By any definition, this is dicta. It is …


The First 48: Ending The Use Of Categorically Unconstitutional Investigative Holds In Violation Of County Of Riverside V. Mclaughlin, Daniel A. Horwitz Dec 2014

The First 48: Ending The Use Of Categorically Unconstitutional Investigative Holds In Violation Of County Of Riverside V. Mclaughlin, Daniel A. Horwitz

Daniel A. Horwitz

This Article critiques the holding adopted by a growing number of courts that law enforcement may delay a warrantless arrestee’s constitutional right to receive a judicial determination of probable cause for up to forty-eight hours following an arrest as long as a judge or magistrate ultimately determines that the arrest itself was supported by probable cause. Although this issue has largely escaped review within academic literature, the practice of employing investigative detentions against warrantless arrestees is widespread among law enforcement. Of note, whether such investigative detentions comport with the Fourth Amendment has also generated a circuit split between the Eighth …


Deadly Force In Memphis: Tennessee V. Garner, John H. Blume Dec 2014

Deadly Force In Memphis: Tennessee V. Garner, John H. Blume

John H. Blume

On October 3, 1974, officers Hymon and Wright of the Memphis Police Department responded to a call about a burglary in progress. When they arrived at the address, a woman standing in the door told the officers that she had heard glass breaking and that someone was breaking into the house next door. Officer Hymon went around the near side of the house. When he reached the backyard, he saw someone run from the back of the house. With his flashlight, he found a person crouched next to a fence at the back of the yard, some thirty to forty …


Random, Suspicionless Searches Of Students' Belongings: A Legal, Empirical, And Normative Analysis, Jason P. Nance Nov 2014

Random, Suspicionless Searches Of Students' Belongings: A Legal, Empirical, And Normative Analysis, Jason P. Nance

Jason P. Nance

This Article provides a legal, empirical, and normative analysis of an intrusive search practice used by schools officials to prevent school crime: random, suspicionless searches of students’ belongings. First, it argues that these searches are not permitted under the Fourth Amendment unless schools have particularized evidence of a weapons or substance problem in their schools. Second, it provides normative considerations against implementing strict security measures in schools, especially when they are applied disproportionately on minority students. Third, drawing on recent restricted data from the U.S. Department of Education’s School Survey on Crime and Safety, it provides empirical findings that raise …


School Security Considerations After Newtown, Jason P. Nance Nov 2014

School Security Considerations After Newtown, Jason P. Nance

Jason P. Nance

On December 14, 2012, and in the weeks thereafter, our country mourned the deaths of twenty children and six educators who were brutally shot and killed at Sandy Hook Elementary School in Newtown, Connecticut. Since the horrific massacre, parents, educators, and lawmakers have understandably turned their attention to implementing stronger security measures in schools. This essay provides important points for policymakers and school officials to consider before embarking on a new phase of school security upgrades.


Students, Security, And Race, Jason P. Nance Nov 2014

Students, Security, And Race, Jason P. Nance

Jason P. Nance

In the wake of the terrible shootings in Newtown, Connecticut, our nation has turned its attention to school security. For example, several states have passed or are considering passing legislation that will provide new funding to schools for security equipment and law enforcement officers. Strict security measures in schools are certainly not new. In response to prior acts of school violence, many public schools for years have relied on metal detectors, random sweeps, locked gates, surveillance cameras, and law enforcement officers to promote school safety. Before policymakers and school officials invest more money in strict security measures, this Article provides …


School Surveillance And The Fourth Amendment, Jason P. Nance Nov 2014

School Surveillance And The Fourth Amendment, Jason P. Nance

Jason P. Nance

In the aftermath of several highly-publicized incidents of school violence, public school officials have increasingly turned to intense surveillance methods to promote school safety. The current jurisprudence interpreting the Fourth Amendment generally permits school officials to employ a variety of strict measures, separately or in conjunction, even when their use creates a prison-like environment for students. Yet, not all schools rely on such strict measures. Recent empirical evidence suggests that low-income and minority students are much more likely to experience intense security conditions in their school than other students, even after taking into account factors such as neighborhood crime, school …


'I Know My Rights, You Go'n Need A Warrant For That:' The Fourth Amendment, Riley's Impact, And Warrantless Searches Of Third-Party Clouds, Laurie Buchan Serafino Sep 2014

'I Know My Rights, You Go'n Need A Warrant For That:' The Fourth Amendment, Riley's Impact, And Warrantless Searches Of Third-Party Clouds, Laurie Buchan Serafino

Laurie B. Serafino

Scholars have frequently suggested that the Fourth Amendment ought to be applied with varying degrees of rigor depending on the seriousness of the crime investigated. Courts have largely rejected such an offense-specific approach to constitutional protections, but have demonstrated deference to the Executive Branch in matters of national security in other contexts. The particularly heightened concern raised by the threat of terrorism suggests that, at least in the context of these most serious of cases, courts ought to engage in some form of balance that recognizes the uniquely strong government interest. Such an approach, however, has to recognize that the …
