Ai Suppression: E-Discovery Software And Brady, Jason Hartline, Liren Shan, Alec Sun, Rebecca Wexler

Faculty Scholarship

Prosecutors regularly rely on AI e-discovery software, known as technology assisted review (TAR) tools, to sort and prioritize digital evidence. These tools implicate constitutional concerns: they can either risk suppressing or help to surface exculpatory and impeachment evidence that prosecutors must disclose under the Brady due process rule. Yet doctrine, agency guidance, and scholarship offer virtually no direction on their use.

This Article examines how TAR affects Brady compliance. Using computer science simulations on synthetic data sets, we show that TAR can either hide or help to expose Brady evidence, depending on how it is configured and the configurations of …

(Mis)Judging Suspicion, Sherri Lee Keene

Georgetown Law Faculty Publications and Other Works

Twenty-five years ago, the Supreme Court decided Illinois v. Wardlow, a Fourth Amendment case that allowed the high-crime nature of a location to be considered in determinations of whether there was reasonable suspicion to support a police stop. In making these determinations, courts rarely acknowledge the role that race can play in decisions that factor in the nature of a location as context. Yet even when the race of a defendant is not mentioned, high-crime area designations can act as a proxy for race inviting racial bias into courts’ analyses. Reasonable suspicion analysis involves the interpretation of a suspect’s …

The Search Of A Search: Moderating Reverse Internet Keyword Warrants, Tui Rademaker

Northwestern University Law Review

Statistics show that Americans consistently turn to Google and other search engines to answer their most personal and private concerns, yet a new investigative tool risks law enforcement having vast discretion in the access of this data. With a keyword warrant, law enforcement can request from a search engine provider (usually Google) a list of probative search queries that users made over a specified time period. Such warrants are beginning to face legal challenges, and so far, courts seem reluctant to recognize the constitutional implications—instead leaving law enforcement with greater potential discretion over their use.

This Note assesses the constitutionality …

The Development And Consequences Of The "Good Faith" Exception To The Exclusionary Rule And The Qualified "Good Faith" Immunity From Liability Under Section 1983, Philip M. Coffin Iii, Paul F. Driscoll

Maine Law Review

The remedies fashioned to redress violations of the fourth amendment to the United States Constitution continue to be the subject of much judicial, legislative, and scholarly inquiry. In striking the balance between the need to protect individual freedom and the need to protect society from criminal activity, the Supreme Court and Congress have developed two principal remedies for fourth amendment violations: the exclusionary rule and civil actions under 42 U.S.C. § 1983 or under theories of constitutional tort. on the development of both of these remedies it is assumed that their effectiveness is the true measure of fourth amendment liberties. …

State V. Cloutier: Implied Invitees, Pretext And Plain View Under The Fourth Amendment, Dennis M. Doiron

Maine Law Review

Law enforcement officers often have occasion to follow the path to the front door of a residence in order to speak to its occupant. Upon answering the door, the occupant may hear a complaint about his barking dog, a query as to whether he witnessed the burglary next door, or a plea seeking support for the police department's Christmas charity drive. Occasionally, a police officer follows the path to a person's door and unexpectedly observes incriminating evidence or activities. In such cases, the police officer's conduct generates the issue of whether his observation implicates the fourth amendment's prohibition against unreasonable …

The Problem Of Third-Party Consent In Fourth Amendment Searches: Toward A "Conservative" Reading Of The Matlock Decision, Robert Deschene

Maine Law Review

In United States v. Matlock, the United States Supreme Court delivered its most recent and comprehensive statement on the doctrine of third-party consent. Under the doctrine, police may search a defendant's home or effects without first obtaining a judicially issued search warrant. Instead of this traditional prerequisite for a valid fourth amendment search, the police need only have the voluntary consent of a third person who possesses "common authority" over or a "sufficient relationship" to the area to be searched. At that point, the defendant's own consent becomes largely irrelevant. Both the United States and Maine constitutions provide protection against …

Crowdsourcing Surveillance, Chaz Arnett

Faculty Scholarship

In Unreasonable: Black Lives, Police Power, and the Fourth Amendment, Devon W. Carbado illuminates how both the spectacular and quotidian forms of racialized terror, brutality, and surveillance—characteristic of enslavement—have shaped the construction of our constitutional order. He argues that the combined social normalization and legal naturalization of racial hierarchy paved the way for the development of slave patrols and other early iterations of policing where incredible acts of violence against Black bodies were made ordinary and essential. He explains how this legacy continues today with Fourth Amendment jurisprudence not simply failing to protect rights but rather licensing police violence …

A Wolf In Sheep’S Attire: How Consent Enfeebles Our Fourth Amendment, Stephen E. Henderson, Guha Krishnamurthi

Faculty Articles

The Fourth Amendment is a mirage. On paper—in the rules studied by law students, analyzed by scholars, and proclaimed by jurists—its limitations are many and, oftentimes, significant. Yet the experience of large numbers of Americans is entirely to the contrary, thanks to the rights-annihilating, under-theorized exception of “consent.” Under its guise, law enforcement officers routinely conduct what would otherwise be constitutionally-restrained searches and seizures, and they do so without meaningful explanation or assent. Fortunately, change—whether legislative or (ideally) constitutional—could be straightforward. Thanks to other sufficient triggers, consent could be replaced by a narrow, rights-protective doctrine under which law enforcement could …

Life, Liberty, And Data Privacy: The Global Cloud, The Criminally Accused, And Executive Versus Judicial Compulsory Process Powers, Rebecca Wexler

Faculty Scholarship

U.S. policymakers’ responses to a wave of global data privacy laws are creating a deep structural unfairness in the criminal legal system. In an era of cloud computing, when data about communications and activities occurring anywhere in the world can be stored on servers located anywhere else, access to such data can make the difference between convictions and acquittals. At the same time, new global data privacy laws risk cutting off cross-border access to digital evidence in criminal investigations. Recognizing the threat to law enforcement interests, U.S. policymakers enacted the CLOUD Act of 2018 to create special procedures for law …

Search And Seizure Budgets, Kiel Brennan-Marquez, Stephen E. Henderson

Faculty Articles

This article proposes a new means of restraining police power: quantitative limits on the number of law enforcement intrusions—searches and seizures—that may occur over a given period of time. Like monetary constraints, search and seizure budgets would aim to curb abusive policing and improve democratic oversight. But unlike their monetary counterparts, budgets would be indexed directly to the specific police activities that most enable escalation and abuse. What is more, budgets are a tool that finds support, conceptually, in the American framing experience. The Fourth Amendment has long been understood to require procedural limits, such as probable cause, on specific …

An Argument Against Unbounded Arrest Power: The Expressive Fourth Amendment And Protesting While Black, Karen Pita Loor

Faculty Scholarship

Protesting is supposed to be revered in our democracy, considered “as American as apple pie” in our nation’s mythology. But the actual experiences of the 2020 racial justice protesters showed that this supposed reverence for political dissent and protest is more akin to American folklore than reality on the streets. The images from those streets depicted police officers clad in riot gear and armed with shields, batons, and “less than” lethal weapons aggressively arresting protesters, often en masse. In the first week of the George Floyd protests, police arrested roughly 10,000 people, and approximately 78 percent of those arrests were …

In Celebration Of Dissents (And Lengthy Textbooks): How Digital Became Different For The Fourth Amendment And Why It Is Time For A Real Warrant Default, Stephen E. Henderson

Faculty Articles

The last decade has brought tremendous change to the Fourth Amendment, finally resulting in a ‘digital is different’ norm. We stand at an inflection point between a monolithic, analog past and a murky future of yet-unarticulated constitutional digital policing rules. It is a good time, then, to reflect upon how we came to be here and where we ought to go. This Essay first looks back to a monumental, majestic dissent: that of Justice Louis Brandeis in the 1928 decision of Olmstead v. United States. Every American, and especially every law student, ought to know that opinion, and judges …

"Hey, Hey! Ho, Ho! These Mass Arrests Have Got To Go!": The Expressive Fourth Amendment Argument, Karen Pita Loor

Faculty Scholarship

The racial justice protests ignited by the murder of George Floyd in May 2020 constitute the largest protest movement in the United States. Estimates suggest that between fifteen and twenty-six million people protested across the country during the summer of 2020 alone. Not only were the number of protestors staggering, but so were the number of arrests. Within one week of when the video of George Floyd’s murder went viral, police arrested ten thousand people demanding justice on American streets, with police often arresting activists en masse. This Essay explores mass arrests and how they square with Fourth Amendment …

Privacy Asymmetries: Access To Data In Criminal Defense Investigations, Rebecca Wexler

Faculty Scholarship

This Article introduces the phenomenon of “privacy asymmetries,” which are privacy statutes that permit courts to order disclosures of sensitive information when requested by law enforcement but not when requested by criminal defense counsel. In the U.S. adversarial criminal legal system, defense counsel are the sole actors tasked with investigating evidence of innocence. Law enforcement has no constitutional, statutory, or formal ethical duty to seek out evidence of innocence. Therefore, statutes that selectively suppress defense investigations selectively suppress evidence of innocence. Privacy asymmetries form a recurring, albeit previously unrecognized, pattern in privacy statutes. They likely arise from legislative oversight and …

Suspects, Cars & Police Dogs: A Complicated Relationship, Brian R. Gallini

Washington Law Review

Officers are searching and arresting vehicle occupants without a warrant with increasing regularity. For justification, this Article demonstrates, lower courts across the country unconstitutionally expand the scope of the Fourth Amendment’s automobile exception—often in the context of a positive dog alert. But Supreme Court jurisprudence specifically limits the scope of the automobile exception to warrantless searches of cars and their containers. In other words, the probable cause underlying the automobile exception allows police to search a vehicle and its containers—nothing more.

Despite that clear guidance, this Article argues that a growing number of lower courts nationwide unconstitutionally rely on the …

State V. Pinkham: Erosion Of Meaningful Forth Amendment Protection For Vehicle Stops In Maine?, Roger M. Clement Jr.

Maine Law Review

In State v. Pinkham, the Maine Supreme Judicial Court, sitting as the Law Court, held that a police officer's stop of a motorist to inquire and advise about the motorist's improper-but not illegal-lane usage did not necessarily violate the Fourth Amendment's proscription against unreasonable seizures. The Pinkham decision is the first time that the Law Court has validated the stop of a moving vehicle in the absence of either a suspected violation of law or an imminent, ongoing threat to highway safety.
This Note considers whether the Law Court was correct in sustaining the police officer's stop of Ronald Pinkham. …

Revitalizing Fourth Amendment Protections: A True Totality Of The Circumstances Test In § 1983 Probable Cause Determinations, Ryan Sullivan

Nebraska College of Law: Faculty Publications

The Article analyzes claims of police misconduct and false arrest, specifically addressing the issue of whether a police officer may ignore evidence of an affirmative defense, such as self-defense, when determining probable cause for an arrest. The inquiry most often arises in § 1983 civil claims for false arrest where the officer was aware of some evidence a crime had been committed, but was also aware of facts indicating the suspect had an affirmative defense to the crime observed. In extreme cases, the affirmative defense at issue is actually self-defense in response to the officer’s own unlawful conduct. As police …

How The Race Of A Neighborhood Criminalizes The Citizens Living Within: A Focus On The Supreme Court And The "High Crime Neighborhood", Deandre' Augustus

St. Thomas Law Review

My whole life I was taught that all men are not created equal. This was beaten into my brain by my loving mother who just wanted me to be safe. You see, this message was part of what most young Black men hear when given “the talk.” I remember multiple variations of the talk given to me throughout my early childhood. However, a variation of the talk was most vividly remembered while taking our dog for a walk around my neighborhood with my mother. At the time, we lived in a suburban area, in a predominantly White neighborhood of Baton …

Cops And Cars: How The Automobile Drove Fourth Amendment Law, Tracey Maclin

Faculty Scholarship

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

The End Of Intuition-Based High-Crime Areas, Ben Grunwald, Jeffrey A. Fagan

Faculty Scholarship

In 2000, the Supreme Court held in Illinois v. Wardlow that a suspect’s presence in a “high-crime area” is relevant in determining whether an officer has reasonable suspicion to conduct an investigative stop. Despite the importance of the decision, the Court provided no guidance about what that standard means, and over fifteen years later, we still have no idea how police officers understand and apply it in practice. This Article conducts the first empirical analysis of Wardlow by examining data on over two million investigative stops conducted by the New York Police Department from 2007 to 2012.

Our results suggest …

Sniffing Out The Fourth Amendment: United States V. Place-Dog Sniffs-Ten Years Later, Hope Walker Hall

Maine Law Review

In the endless and seemingly futile government war against drugs, protections afforded by the Fourth Amendment of the United States Constitution may have fallen by the wayside as courts struggle to deal with drug offenders. The compelling government interest in controlling the influx of drugs all too often results in a judicial attitude that the ends justify the means. Judges can be reluctant to exclude evidence of drugs found in an unlawful search pursuant to the exclusionary rule, which provides that illegally obtained evidence may not be used at trial. The exclusion of drugs as evidence in drug cases often …

Whren V. United States: An Abrupt End To The Debate Over Pretextual Stops, Brian J. O'Donnell

Maine Law Review

In Whren v. United States, the United States Supreme Court held that a traffic stop is reasonable under the Fourth Amendment if a police officer has probable cause to believe that a traffic violation has occurred, even if the stop is a pretext for the investigation of a more serious offense. The Court affirmed the convictions of Michael A. Whren and James L. Brown, who had been arrested on federal drug charges after Washington, D.C., police stopped Brown for minor traffic infractions. The Court's unanimous opinion, delivered by Justice Scalia, brought an end to a long-running debate over the proper …

Standing Under State Search And Seizure Provision: Why The Minnesota Supreme Court Should Have Rejected The Federal Standards And Instead Invoked Greater Protection Under Its Own Constitution In State V. Carter, Rebecca C. Garrett

Maine Law Review

In State v. Carter, the Minnesota Supreme Court considered whether a criminal defendant had “standing” to challenge an alleged search under the Fourth Amendment and Article 1, Section 10 of the Minnesota Constitution. The defendant moved to suppress evidence obtained by a police officer who had peered in the window of an apartment where the defendant was participating in a drug-packaging operation with the apartment's leaseholder. A divided court held that the defendant had a legitimate expectation of privacy in the apartment. Therefore, the defendant had standing to challenge the legality of the police officer's observations pursuant to the Fourth …

Legal Consciousness As Race Consciousness: Expansion Of The Fourth Amendment Seizure Analysis Through Objective Knowledge Of Police Impunity, Lindsey Webb

Sturm College of Law: Faculty Scholarship

Encounters between police officers and members of the community are deeply influenced by race. Yet when courts assess whether police officers have complied with the Fourth Amendment, they explicitly exclude consideration of the ways in which the police-civilian interaction was influenced by racial bias, assumptions, and fear. In determining whether law enforcement officers seized a civilian, for example, courts look to the objective circumstances of the event, such as the number of officers involved, whether police weapons were drawn, and the tone of voice the officers used. They then assess whether, under such circumstances, a reasonable person would feel free …
