The Inverse Relationship Between The Constitutionality And Effectiveness Of New York City "Stop And Frisk", Jeffrey Bellin Sep 2019

The Inverse Relationship Between The Constitutionality And Effectiveness Of New York City "Stop And Frisk", Jeffrey Bellin

Jeffrey Bellin

New York City sits at the epicenter of an extraordinary criminal justice phenomenon. While employing aggressive policing tactics, such as “stop and frisk,” on an unprecedented scale, the City dramatically reduced both violent crime and incarceration – with the connections between these developments (if any) hotly disputed. Further clouding the picture, in August 2013, a federal district court ruled the City’s heavy reliance on “stop and frisk” unconstitutional. Popular and academic commentary generally highlights isolated pieces of this complex story, constructing an incomplete vision of the lessons to be drawn from the New York experience. This Article brings together all …


The Mosaic Theory Of The Fourth Amendment, Orin S. Kerr Jul 2019

The Mosaic Theory Of The Fourth Amendment, Orin S. Kerr

Orin Kerr

In the Supreme Court's recent decision on GPS surveillance, United States v. Jones, five justices authored or joined concurring opinions that applied a new approach to interpreting Fourth Amendment protection. Before Jones, Fourth Amendment decisions had always evaluated each step of an investigation individually. Jones introduced what we might call a "mosaic theory" of the Fourth Amendment, by which courts evaluate a collective sequence of government activity as an aggregated whole to consider whether the sequence amounts to a search. This Article considers the implications of a mosaic theory of the Fourth Amendment. It explores the choices and puzzles that …


Carpenter V. United States And The Fourth Amendment: The Best Way Forward, Stephen E. Henderson Dec 2017

Carpenter V. United States And The Fourth Amendment: The Best Way Forward, Stephen E. Henderson

Stephen E Henderson

We finally have a federal ‘test case.’  In Carpenter v. United States, the Supreme Court is poised to set the direction of the Fourth Amendment in the digital age.  The case squarely presents how the twentieth-century third party doctrine will fare in contemporary times, and the stakes could not be higher.  This Article reviews the Carpenter case and how it fits within the greater discussion of the Fourth Amendment third party doctrine and location surveillance, and I express a hope that the Court will be both a bit ambitious and a good measure cautious. 
 
As for ambition, the …


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. …


Small Cells, Big Problems: The Increasing Precision Of Cell Site Location Information And The Need For Fourth Amendment Protections, Robert M. Bloom, William T. Clark May 2017

Small Cells, Big Problems: The Increasing Precision Of Cell Site Location Information And The Need For Fourth Amendment Protections, Robert M. Bloom, William T. Clark

Robert M. Bloom

The past fifty years has witnessed an evolution in technology advancement in police surveillance. Today, one of the essential tools of police surveillance is something most Americans carry with them in their pockets every day, the cell phone. Cell phones not only contain a huge repository of personal data, they also provide continuous surveillance of a person’s movement known as cell site location information (CSLI). In 1986, Congress sought to provide some privacy protections to CSLI in the Stored Communication Act. Although this solution may have struck the proper balance in an age when cell phones were a mere novelty …


Lawn Signs: A Fourth Amendment For Constitutional Curmudgeons, Stephen E. Henderson, Andrew G. Ferguson Dec 2015

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

Stephen E Henderson

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 …


Fourth Amendment Time Machines (And What They Might Say About Police Body Cameras), Stephen E. Henderson Dec 2015

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

Stephen E Henderson

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 …


A Linguistic Analysis Of The Meanings Of "Search" In The Fourth Amendment: A Search For Common Sense, Clark D. Cunningham Nov 2015

A Linguistic Analysis Of The Meanings Of "Search" In The Fourth Amendment: A Search For Common Sense, Clark D. Cunningham

Clark D. Cunningham

This article offers a new technique for analyzing and evaluating competing interpretations of a legal text and applies that technique to one of the most debated questions of modern constitutional interpretation: the meaning of "searches" in the first clause of the fourth amendment. This Technique is called the "common sense" approach because it begins with a semantic analysis of the text in terms of the sense that the key words have in everyday speech. Such analysis reveals a complex of interlocked concepts that underlies the ability of speakers to recognize meaningful uses of these words. The common sense approach then …


Testimony On Oklahoma Civil Asset Forfeiture Reform, Stephen E. Henderson Aug 2015

Testimony On Oklahoma Civil Asset Forfeiture Reform, Stephen E. Henderson

Stephen E Henderson

I am grateful for the opportunity to speak to you today about Senate Bill 838 and the reform of Oklahoma’s civil asset forfeiture. I am a professor of law at the University of Oklahoma, where my teaching and research focus on criminal law and procedure. I have experience achieving consensus solutions in contested areas of law, most notably in the six years I spent drafting a new set of ABA Criminal Justice Standards, and I know that change is rarely easy. No matter the topic and whatever the status quo, there is sure to be someone who feels it is …

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 …

Search, Seizure, And Immunity: Second-Order Normative Authority And Rights, Stephen E. Henderson, Kelly Sorensen Dec 2012

Search, Seizure, And Immunity: Second-Order Normative Authority And Rights, Stephen E. Henderson, Kelly Sorensen

Stephen E Henderson

A paradigmatic aspect of a paradigmatic kind of right is that the rights holder is the only one who can alienate it. When individuals waive rights, the normative source of that waiving is normally taken to be the individual herself. This moral feature—immunity—is usually in the background of discussions about rights. We bring it into the foreground here, with specific attention to a recent U.S. Supreme Court decision, Kentucky v. King (2011), concerning search and seizure rights. An entailment of the Court’s decision is that, at least in some cases, a right can be removed by the intentional actions of …
