Aerial Trespass And The Fourth Amendment, Randall F. Khalil

Michigan Law Review

Since 1973, courts have analyzed aerial surveillance under the Fourth Amendment by applying the test from Katz v. United States, which states that a search triggers the Fourth Amendment when a government actor violates a person’s “reasonable expectation of privacy.” The Supreme Court applied Katz to aerial surveillance three times throughout the 1980s, yet this area of the law remains unsettled and outcomes are unpredictable. In 2012, the Supreme Court recognized an alternative to the Katz test in Jones v. United States, which held that a search triggers the Fourth Amendment when a government actor physically intrudes into …

Giving The Fourth Amendment Meaning: Creating An Adversarial Warrant Proceeding To Protect From Unreasonable Searches And Seizures, Ben Mordechai-Strongin

University of Michigan Journal of Law Reform

For at least the past 40 years, police and prosecutors have had free reign in conducting illegal searches and seizures nominally barred by the Fourth Amendment. The breadth of exceptions to the warrant requirement, the lax interpretation of probable cause, and especially the “good faith” doctrine announced in U.S. v. Leon have led to severe violations of privacy rights, trauma to those wrongly searched or seized, and a court system overburdened by police misconduct cases. Most scholars analyzing the issue agree that the rights guaranteed by the Fourth Amendment—to be free from unreasonable search and seizure—have been severely eroded or …

Pocket Police: The Plain Feel Doctrine Thirty Years Later, Kelly Recker

Michigan Law Review

The idea that a police officer can park in a low-income neighborhood, pull someone over because of their race, frisk everyone in the car, let them go if their pockets are empty, and do the whole thing over and over again until the officer finds something illegal seems deeply upsetting and violative, to say the least. And yet, pretextual traffic stops are constitutional per a unanimous Supreme Court in Whren v. United States, 517 U.S. 806 (1996), as is seizing obvious contraband during a frisk per Minnesota v. Dickerson, 508 U.S. 366 (1993). In the thirty years since …

Deprogramming Bias: Expanding The Exclusionary Rule To Pretextual Traffic Stop Using Data From Autonomous Vehicle And Drive-Assistance Technology, Joe Hillman

University of Michigan Journal of Law Reform

As autonomous vehicles become more commonplace and roads become safer, this new technology provides an opportunity for courts to reconsider the constitutional rationale of modern search and seizure law. The Supreme Court should allow drivers to use evidence of police officer conduct relative to their vehicle’s technological capabilities to argue that a traffic stop was pretextual, meaning they were stopped for reasons other than their supposed violation. Additionally, the Court should expand the exclusionary rule to forbid the use of evidence extracted after a pretextual stop. The Court should retain some exceptions to the expanded exclusionary rule, such as when …

“Bang!”: Shotspotter Gunshot Detection Technology, Predictive Policing, And Measuring Terry’S Reach, Harvey Gee

University of Michigan Journal of Law Reform

ShotSpotter technology is a rapid identification and response system used in ninety American cities that is designed to detect gunshots and dispatch police. ShotSpotter is one of many powerful surveillance tools used by local police departments to purportedly help fight crime, but they often do so at the expense of infringing upon privacy rights and civil liberties. This Article expands the conversation about ShotSpotter technology considerably by examining the adjacent Fourth Amendment issues emanating from its use. For example, law enforcement increasingly relies on ShotSpotter to create reasonable suspicion where it does not exist. In practice, the use of ShotSpotter …

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

Michigan Law Review

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 …

Another Katz Moment?: Privacy, Property, And A Dna Database, Claire Mena

University of Michigan Journal of Law Reform

The Fourth Amendment protects the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” The understanding of these words seems to shift as new technologies emerge. As law enforcement’s arsenal of surveillance techniques has grown to include GPS tracking, cell phones, and cell site location information (CSLI), the Supreme Court has applied Fourth Amendment protections to these modern tools. Law enforcement continues to use one pervasive surveillance technique without limitations: the routine collection of DNA. In 2013, the Supreme Court in Maryland v. King held that law enforcement may routinely …

Social Norms In Fourth Amendment Law, Matthew Tokson, Ari Ezra Waldman

Michigan Law Review

Courts often look to existing social norms to resolve difficult questions in Fourth Amendment law. In theory, these norms can provide an objective basis for courts’ constitutional decisions, grounding Fourth Amendment law in familiar societal attitudes and beliefs. In reality, however, social norms can shift rapidly, are constantly being contested, and frequently reflect outmoded and discriminatory concepts. This Article draws on contemporary sociological literatures on norms and technology to reveal how courts’ reliance on norms leads to several identifiable errors in Fourth Amendment jurisprudence.

Courts assessing social norms generally adopt what we call the closure principle, or the idea that …

Border Searches For Investigatory Purposes: Implementing A Border Nexus Standard, Brenna Ferris

University of Michigan Journal of Law Reform Caveat

Border searches are a commonly used exception to the Fourth Amendment’s probable cause and warrant requirements. Using a border search, the government can conduct searches of individuals without any kind of individualized suspicion. Border searches pose a concerning risk to privacy when they are used as a tool for criminal investigations. The Supreme Court has never ruled on searches used in this way, but lower courts are addressing the technique and reaching conflicting decisions. Courts need to take an approach that will protect the privacy interests of individuals while allowing the government to advance its interests in protecting its borders …

The Sacred Fourth Amendment Text, Christopher Slobogin

Michigan Law Review Online

The Supreme Court’s jurisprudence governing the Fourth Amendment’s “threshold”—a word meant to refer to the types of police actions that trigger the amendment’s warrant and reasonableness requirements—has confounded scholars and students alike since Katz v. United States. Before that 1967 decision, the Court’s decisions on the topic were fairly straightforward, based primarily on whether the police trespassed on the target’s property or property over which the target had control. After that decision—which has come to stand for the proposition that a Fourth Amendment search occurs if police infringe an expectation of privacy that society is prepared to recognize as …

How Definitive Is Fourth Amendment Textualism?, Evan H. Caminker

Michigan Law Review Online

Professor Jeffrey Bellin’s excellent article advances a comprehensive and straightforward textual approach to determining what policing activities constitute “searches” triggering the protections of the Fourth Amendment. Bellin’s thesis is that a text-based approach to interpreting the Amendment is superior to the Supreme Court’s current approach, which ever since Katz v. United States has defined “search” primarily by reference to a non-textual “reasonable expectation of privacy” standard. After soundly criticizing the ungrounded and highly subjective nature of the Katz test, Bellin declares that the Court should instead simply follow where the text leads: the Amendment protects people from a search, meaning …

A Small But Mighty Docket: Select Criminal Law And Procedure Cases From The Supreme Court's 2019-20 Term, Eve Brensike Primus, Jeremy Shur

Articles

With its 2019-20 Term disrupted by the COVID-19 pandemic, the Supreme Court released just 53 signed decisions, the fewest decisions in a Term since the Civil War. But the Court's lighter docket still featured important criminal law and procedure cases touching on what constitutes reasonable individualized suspicion, the necessity of jury unanimity, and the proper form of the insanity defense.

Location Tracking And Digital Data: Can Carpenter Build A Stable Privacy Doctrine?, Evan H. Caminker

Articles

In Carpenter v United States, the Supreme Court struggled to modernize twentieth-century search and seizure precedents for the “Cyber Age.” Twice previously this decade the Court had tweaked Fourth Amendment doctrine to keep pace with advancing technology, requiring a search warrant before the government can either peruse the contents of a cell phone seized incident to arrest or use a GPS tracker to follow a car’s long-term movements.

Tort Justice Reform, Paul David Stern

University of Michigan Journal of Law Reform

This Article calls for a comprehensive reform of public tort law with respect to law enforcement conduct. It articulates an effective and equitable remedial regime that reconciles the aspirational goals of public tort law with the practical realities of devising payment and disciplinary procedures that are responsive to tort settlements and judgments. This proposed statutory scheme seeks to deter law enforcement misconduct without disincentivizing prudent officers from performing their duties or overburdening them with extensive litigation. Rather than lamenting the dissolution of Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics or the insurmountability of qualified immunity, reform …

The Quantum Of Suspicion Needed For An Exigent Circumstances Search, Kit Kinports

University of Michigan Journal of Law Reform

For decades, the United States Supreme Court opinions articulating the standard of exigency necessary to trigger the exigent circumstances exception to the Fourth Amendment’s warrant requirement have been maddeningly opaque and confusing. Some cases require probable cause, others call for reasonable suspicion, and still, others use undefined and unhelpful terms such as “reasonable to believe” in describing how exigent the situation must be to permit the police to proceed without a warrant. Not surprisingly, the conflicting signals coming from the Supreme Court have led to disagreement in the lower courts.

To resolve this conflict and provide guidance to law enforcement …

Policing, Danger Narratives, And Routine Traffic Stops, Jordan Blair Woods

Michigan Law Review

This Article presents findings from the largest and most comprehensive study to date on violence against the police during traffic stops. Every year, police officers conduct tens of millions of traffic stops. Many of these stops are entirely unremarkable—so much so that they may be fairly described as routine. Nonetheless, the narrative that routine traffic stops are fraught with grave and unpredictable danger to the police permeates police training and animates Fourth Amendment doctrine. This Article challenges this dominant danger narrative and its centrality within key institutions that regulate the police.

The presented study is the first to offer an …

Forensic Border Searches After Carpenter Require Probable Cause And A Warrant, Christopher I. Pryby

Michigan Law Review

Under the border search doctrine, courts have upheld the federal government's practice of searching people and their possessions upon entry into or exit from the United States, without any requirement of suspicion, as reasonable under the Fourth Amendment. Since the advent of electronic devices with large storage capacities, courts have grappled with whether this definition of reasonableness continues to apply. So far, courts have consistently characterized “nonforensic” border inspections of electronic devices (for example, paging through photos on a phone) as “routine” searches that, like inspecting luggage brought across international lines, require no suspicion. But there is a circuit split …

Carpenter's Legacy: Limiting The Scope Of The Electronic Private Search Doctrine, Sarah A. Mezera

Michigan Law Review

One of the most significant challenges confronting courts and legal scholars in the twenty-first century is the application of Fourth Amendment doctrine to new technology. The circuit split over the application of the private search doctrine to electronic devices exemplifies how courts struggle to apply old doctrines to new circumstances. Some courts take the position that the old doctrine should apply consistently in the new context. Other courts have changed the scope of the old doctrine in order to account for the change in circumstances. The Supreme Court took the latter position in Carpenter v. United States and held that …

Secret Searches: The Sca's Standing Conundrum, Aviv S. Halpern

Michigan Law Review

The Stored Communications Act (“SCA”) arms federal law enforcement agencies with the ability to use a special type of warrant to access users’ electronically stored communications. In some circumstances, SCA warrants can require service providers to bundle and produce a user’s electronically stored communications without ever disclosing the existence of the warrant to the individual user until charges are brought. Users that are charged will ultimately receive notice of the search after the fact through their legal proceedings. Users that are never charged, however, may never know that their communications were obtained and searched. This practice effectively makes the provisions …

Fourth Amendment Textualism, Jeffrey Bellin

Michigan Law Review

The Fourth Amendment’s prohibition of “unreasonable searches” is one of the most storied constitutional commands. Yet after decades of Supreme Court jurisprudence, a coherent definition of the term “search” remains surprisingly elusive. Even the justices know they have a problem. Recent opinions only halfheartedly apply the controlling “reasonable expectation of privacy” test and its wildly unpopular cousin, “third-party doctrine,” with a few justices in open revolt.

These fissures hint at the Court’s openness to a new approach. Unfortunately, no viable alternatives appear on the horizon. The justices themselves offer little in the way of a replacement. And scholars’ proposals exhibit …

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …

Fourth Amendment Fairness, Richard M. Re

Michigan Law Review

Fourth Amendment doctrine is attentive to a wide range of interests, including security, informational privacy, and dignity. How should courts reconcile these competing concerns when deciding which searches and seizures are “unreasonable”? Current doctrine typically answers this question by pointing to interest aggregation: the various interests at stake are added up, placed on figurative scales, and compared, with the goal of promoting overall social welfare. But interest aggregation is disconnected from many settled doctrinal rules and leads to results that are unfair for individuals. The main alternative is originalism; but historical sources themselves suggest that the Fourth Amendment calls for …

The Fourth Amendment Categorical Imperative, David Gray

Michigan Law Review Online

The vast majority of current Fourth Amendment doctrine is unfounded, incoherent, and dangerous. The culprit is the Supreme Court’s 1967 decision in Katz v. United States, which defines “search” as government conduct that violates subjectively manifested expectations of privacy “that society is prepared to recognize as ‘reasonable.’ ” This is pure applesauce. Nowhere will you find a standard dictionary that defines “search” in these terms. Neither will you hear a native speaker of the English language use “search” in this sense unless her mind has been polluted by a semester of studying criminal procedure. The Court created this definition …

The Effect Of Legislation On Fourth Amendment Protection, Orin S. Kerr

Michigan Law Review

When judges interpret the Fourth Amendment, and privacy legislation regulates the government’s conduct, should the legislation have an effect on the Fourth Amendment? Courts are split three ways. Some courts argue that legislation provides the informed judgment of a coequal branch that should influence the Fourth Amendment. Some courts contend that the presence of legislation should displace Fourth Amendment protection to prevent constitutional rules from interfering with the legislature’s handiwork. Finally, some courts treat legislation and the Fourth Amendment as independent and contend that the legislation should have no effect. This Article argues that courts should favor interpreting the Fourth …

Why Arrest?, Rachel A. Harmon

Michigan Law Review

Arrests are the paradigmatic police activity. Though the practice of arrests in the United States, especially arrests involving minority suspects, is under attack, even critics widely assume the power to arrest is essential to policing. As a result, neither commentators nor scholars have asked why police need to make arrests. This Article takes up that question, and it argues that the power to arrest and the use of that power should be curtailed. The twelve million arrests police conduct each year are harmful not only to the individual arrested but also to their families and communities and to society as …

Tightening The Ooda Loop: Police Militarization, Race, And Algorithmic Surveillance, Jeffrey L. Vagle

Michigan Journal of Race and Law

This Article examines how military automated surveillance and intelligence systems and techniques, when used by civilian police departments to enhance predictive policing programs, have reinforced racial bias in policing. I will focus on two facets of this problem. First, I investigate the role played by advanced military technologies and methods within civilian police departments. These approaches have enabled a new focus on deterrence and crime prevention by creating a system of structural surveillance where decision support relies increasingly upon algorithms and automated data analysis tools and automates de facto penalization and containment based on race. Second, I will explore these …

Closing The Gap Between What Is Lawful And What Is Right In Police Use Of Force Jurisprudence By Making Police Departments More Democratic Institutions, Jonathan M. Smith

Michigan Journal of Race and Law

On August 9, 2014, Michael Brown was shot to death in Ferguson, Missouri, by police officer Darren Wilson. Members of the Ferguson community rose up in response. Protests demanding that police violence against African Americans cease and that accountability for police misconduct be addressed erupted across the country, and they have not subsided since. Incidents in Baltimore, Maryland; Chicago, Illinois; WallerCounty, Texas; and elsewhere have kept the movement alive. The mass media, the political elite, and the White middle class woke up to a reality that had been long known to communities of color – force is used disproportionately against …

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, …

Voluntary Disclosure Of Information As A Proposed Standard For The Fourth Amendment's Third-Party Doctrine, Margaret E. Twomey

Michigan Telecommunications & Technology Law Review

The third-party doctrine is a long-standing tenant of Fourth Amendment law that allows law enforcement officers to utilize information that was released to a third party without the probable cause required for a traditional search warrant. This has allowed law enforcement agents to use confidential informants, undercover agents, and access bank records of suspected criminals. However, in a digital age where exponentially more information is shared with Internet Service Providers, e-mail hosts, and social media “friends,” the traditional thirdparty doctrine ideas allow law enforcement officers access to a cache of personal information and data with a standard below probable cause. …
