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.

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 …

Lawn Signs: A Fourth Amendment For Constitutional Curmudgeons, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

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 …

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, …
