Lawn Signs: A Fourth Amendment For Constitutional Curmudgeons, Andrew Ferguson, Stephen E. Henderson

Faculty Articles

What is the constitutional significance of the proverbial “keep off the grass” sign? This question—asked by curmudgeonly neighbors everywhere—has been given new currency in a recent decision by the United States Supreme Court. Indeed, Florida v. Jardines might have bestowed constitutional curmudgeons with significant new Fourth Amendment protections. By expressing expectations regarding—and control over—access to property, “the people” may be able to claim greater Fourth Amendment protections not only for their homes, but also for their persons, papers, and effects. This article launches a constitutionally grounded, but lighthearted campaign of citizen education and empowerment: Fourth Amendment LAWn signs. With every …

A Rose By Any Other Name: Regulating Law Enforcement Bulk Metadata Collection, Stephen E. Henderson

Faculty Articles

In Other People’s Papers, Jane Bambauer argues for careful reform of the Fourth Amendment’s third party doctrine, providing an important contribution to an increasingly rich field of scholarship, judicial opinion, statute, and law reform. Bambauer is especially concerned with access to bodies of third-party data that can be filtered and mined, as they can be privacy invasive but also effective and less subject to traditional investigative prejudices and limitations. Although her article provocatively overclaims in trying to set itself apart from existing proposals, by analyzing existing constitutional and statutory law—including what I have termed a “limited” third party doctrine—and comparing …

Teaching Criminal Procedure: Why Socrates Would Use Youtube, Stephen E. Henderson, Joseph Thai

Faculty Articles

In this invited contribution to the Law Journal's annual Teaching Issue, we pay some homage to the great philosopher whose spirit allegedly guides our classrooms, in service of two concrete goals. One, we employ dialogue to describe the “nuts and bolts” of teaching Criminal Procedure, most of which are equally relevant to any doctrinal law school course (including course description, office hours, seating charts and attendance, class decorum and recording, student participation, laptops, textbooks, class preparation and presentation, and exams). Two, we explain the benefits of using multimedia in the classroom, including a few of the many modules found on …

What's Fear Got To Do With It?: The "Armed And Dangerous" Requirement Of Terry, Gerald S. Reamey

Marquette Law Review

Rarely has a court’s opinion, even one from the Supreme Court of the United States, so altered existing notions of constitutional criminal procedure law as did the opinion in Terry v. Ohio. On several levels, the opinion dramatically shifted the way in which the Fourth Amendment was understood. Law students who had learned about the probable cause “requirement” and the warrant “requirement” were surprised to learn, especially in the case of the former, that these “requirements” were not required at all. To continue to conceptualize the Fourth Amendment’s single sentence guarantees as consisting of a “warrant clause” and a “reasonableness” …

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

Faculty Scholarship

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 …

Heien'S Mistake Of Law, Kit Kinports

Faculty Scholarship

The Supreme Court has been whittling away at the Fourth Amendment for decades. The Court's 2014 ruling in Heien v. North Carolina allowing the police to make a traffic stop based on a reasonable mistake of law generated little controversy among the Justices and escaped largely unnoticed by the press-perhaps because yet another Supreme Court decision reading the Fourth Amendment narrowly is not especially noteworthy or because the opinion's cursory and overly simplistic analysis equating law enforcement's reasonable mistakes of fact and law minimized the significance of the Court's decision. But the temptation to dismiss Heien as just another small …

The Sixth Pillar Of Anti-Money Laundering Compliance: Balancing Effective Enforcement With Financial Privacy, Maria A. De Dios

Brooklyn Journal of Corporate, Financial & Commercial Law

The U.S. government has responded to the increase of financial crimes, including money laundering and terrorist financing, by requiring that financial institutions implement anti-money laundering compliance programs within their institutions. Most recently, the Financial Crimes Enforcement Network exercised its regulatory powers, as authorized by the Treasury Department, by proposing regulations that now explicitly add customer due diligence to the preexisting anti-money laundering regime. The policy behind the government’s legislative and regulatory measures is clear—financial institutions must ensure that they are protected from and not aiding in the illegal efforts of criminals. The complexity and insidiousness of these financial crimes makes …

Trying To Fit A Square Peg Into A Round Hole: Why Title Ii Of The Americans With Disabilities Act Must Apply To All Law Enforcement Services, Michael Pecorini

Journal of Law and Policy

Police use of force has been subject to greater scrutiny in recent years in the wake of several high-profile killings of African Americans. Less attention, however, has been paid to the increasingly routine violent encounters between police and individuals with mental illness or intellectual and development disabilities (“I/DD”). This is particularly problematic, as police have become the de-facto first responders to these individuals and far too often police responses to these individuals result in tragedy.

This Note argues that the Americans with Disabilities Act requires law enforcement to provide reasonable accommodations during their interactions with and seizures of individuals with …

Anthony Amsterdam's Perspectives On The Fourth Amendment, And What It Teaches About The Good And Bad In Rodriguez V. United States, Tracey Maclin

Faculty Scholarship

Anthony Amsterdam’s article, Perspectives On The Fourth Amendment is one of the best, if not the best, law review article written on the Fourth Amendment. Thus, Minnesota Law Review on its hundredth anniversary fittingly recognizes and honors Professor Amsterdam’s article in its Symposium edition, “Standing on the Shoulders of Giants: Celebrating 100 Volumes of the Minnesota Law Review.” I am flattered that the Law Review invited me to participate in this Symposium.

/="/">Specifically, my article connects two perspectives from Amsterdam’s article — the Fourth Amendment’s concern with discretionary police power and the Framers’ vision of the Fourth Amendment …

Evidence Laundering In A Post-Herring World, Kay L. Levine, Jenia I. Turner, Ronald F. Wright

Faculty Journal Articles and Book Chapters

The Supreme Court’s decision in Herring v. United States authorizes police to defeat the Fourth Amendment’s protections through a process we call evidence laundering. Evidence laundering occurs when one police officer makes a constitutional mistake when gathering evidence and then passes that evidence along to a second officer, who develops it further and then delivers it to prosecutors for use in a criminal case. When courts admit the evidence based on the good faith of the second officer, the original constitutional taint disappears in the wash.

In the years since Herring was decided, courts have allowed evidence laundering in a …

Policing In The Era Of Permissiveness: Mitigating Misconduct Through Third-Party Standing, Julian A. Cook

Scholarly Works

On April 4, 2015, Walter L. Scott was driving his vehicle when he was stopped by Officer Michael T. Slager of the North Charleston, South Carolina, police department for a broken taillight. A dash cam video from the officer’s vehicle showed the two men engaged in what appeared to be a rather routine verbal exchange. Sometime after Slager returned to his vehicle, Scott exited his car and ran away from Slager, prompting the officer to pursue him on foot. After he caught up with Scott in a grassy field near a muffler establishment, a scuffle between the men ensued, purportedly …

Whither Reasonable Suspicion: The Supreme Court's Functional Abandonment Of The Reasonableness Requirement For Fourth Amendment Seizures, Steven P. Grossman

All Faculty Scholarship

Although the United States Supreme Court’s approach to issues governing application of the probable cause requirement of the Fourth Amendment has mutated over the years, at least one aspect of its approach has remained constant. Before information leading to probable cause or its lesser iteration of reasonable suspicion is found to exist, the government must demonstrate in some meaningful way the reliability of the person providing the information or of the information itself. Lacking such reliability, no search or seizure based on probable cause or reasonable suspicion is permitted. In its recent decision in Navarette v. California, the Court largely …

A Hurdle Too High: The Unconstitutionality Of Mandatory Ultrasounds Under Casey's Undue Burden Standard, Katarzyna Kordas

Cardozo Journal of Equal Rights & Social Justice

The article argues that mandatory ultrasound laws impose an undue burden on women seeking abortions, violating the constitutional standard established in Planned Parenthood v. Casey. These laws, often enacted to dissuade women from proceeding with abortions, are deemed medically unnecessary and unconstitutional as they obstruct women's reproductive rights.

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …

Policing Criminal Justice Data, Wayne Logan, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

This article addresses a matter of fundamental importance to the criminal justice system: the presence of erroneous information in government databases and the limited government accountability and legal remedies for the harm that it causes individuals. While a substantial literature exists on the liberty and privacy perils of large multi-source data assemblage, often termed "big data," this article addresses the risks associated with the collection, generation and use of "small data" (i.e., individual-level, discrete data points). Because small data provides the building blocks for all data-driven systems, enhancing its quality will have a significant positive effect on the criminal justice …

Fourth Amendment Time Machines (And What They Might Say About Police Body Cameras), Stephen E. Henderson

Faculty Articles

When it comes to criminal investigation, time travel is increasingly possible. Despite longstanding roots in traditional investigation, science is today providing something fundamentally different in the form of remarkably complete digital records. And those big data records not only store our past, but thanks to data mining they are in many circumstances eerily good at predicting our future. So, now that we stand on the threshold of investigatory time travel, how should the Fourth Amendment and legislation respond? How should we approach bulk government capture, such as by a solar-powered drone employing wide-area persistent stare technology? Is it meaningfully different …

Search Incident To Probable Cause?: The Intersection Of Rawlings And Knowles, Marissa Perry

Michigan Law Review

The search incident to arrest exception authorizes an officer to search an arrestee’s person and his or her area of immediate control. This exception is based on two historical justifications: officer safety and evidence preservation. While much of search incident to arrest doctrine is settled, tension exists between two Supreme Court cases, Rawlings v. Kentucky and Knowles v. Iowa, and a crucial question remains unanswered: Must an officer decide to make an arrest prior to commencing a search? In Rawlings, the Supreme Court stated that a search may precede a formal arrest if the arrest follows quickly thereafter. In Knowles, …

Digital Border Searches After Riley V. California, Thomas Mann Miller

Washington Law Review

The federal government claims that the Fourth Amendment permits it to search digital information on cell phones, laptops, and other electronic devices at the international border without suspicion of criminal activity, much less a warrant. Until recently, federal courts have generally permitted these digital border searches, treating them no differently from searches of luggage. Courts that have limited digital border searches have required only that the government establish reasonable suspicion for the most exhaustive kind of digital search. The Supreme Court has not yet weighed in, but last year it held in Riley v. California that the search incident to …

Neuro Lie Detection And Mental Privacy, Madison Kilbride, Jason Iuliano

Maryland Law Review

New technologies inevitably raise novel legal questions. This is particularly true of technologies, such as neuro lie detection, that offer new ways to investigate crime. Recently, a number of scholars have asked whether neuro lie detection testing is constitutional. So far, the debate has focused on the Fifth Amendment—specifically whether evidence gathered through neuro lie detection is constitutionally admissible because it is “physical” in nature or inadmissible because it is “testimonial” in nature. Under current Supreme Court doctrine, this Fifth Amendment debate is intractable. However, the more fundamental question of whether the government can compel individuals to undergo a neuro …
