The Fourth Amendment And New Technologies: Constitutional Myths And The Case For Caution, Orin S. Kerr Jul 2019

The Fourth Amendment And New Technologies: Constitutional Myths And The Case For Caution, Orin S. Kerr

Orin Kerr

To one who values federalism, federal preemption of state law may significantly threaten the autonomy and core regulatory authority of The Supreme Court recently considered whether a1mmg an infrared thermal imaging device at a suspect's home can violate the Fourth Amendment. Kyllo v. United States announced a new and comprehensive rule: the government's warrantless use of senseenhancing technology that is "not in general use" violates the Fourth Amendment when it yields "details of the home that would previously have been unknowable without physical intrusion." Justice Scalia's majority opinion acknowledged that the Court's rule was not needed to resolve the case …


A Cognitive Theory Of The Third-Party Doctrine And Digital Papers, H. Brian Holland Nov 2018

A Cognitive Theory Of The Third-Party Doctrine And Digital Papers, H. Brian Holland

H. Brian Holland

For nearly 200 years, an individual’s personal papers enjoyed near-absolute protection from government search and seizure. That is no longer the case. With the widespread adoption of cloud-based information processing and storage services, the third-party doctrine operates to effectively strip our digital papers of meaningful Fourth Amendment protections.

This Article presents a new approach to reconciling current third-party doctrine with the technological realities of modern personal information processing. Our most sensitive data is now processed and stored on cloud computing systems owned and operated by third parties.  Although we may consider these services to be private and generally secure, the …


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. …


Testimony On Unmanned Aircraft Systems Rules And Regulations, Stephen E. Henderson Sep 2016

Testimony On Unmanned Aircraft Systems Rules And Regulations, Stephen E. Henderson

Stephen E Henderson

Chairman Barrington, Vice Chair Brooks, members of the Committee on Public Safety, Senators, and distinguished guests, I am grateful for the opportunity to speak to you today about unmanned aerial systems, or drones, and more particularly about their federal constitutional implications and what might be the constitutional restrictions on any legislation you might like to enact. I am the Judge Haskell A. Holloman Professor of Law at the University of Oklahoma, where my teaching and research focus on criminal law and procedure and privacy, including the constitutional rights pertaining thereto.

My topic is not an easy one. The constitutional law …


If You Fly A Drone, So Can Police, Stephen E. Henderson May 2016

If You Fly A Drone, So Can Police, Stephen E. Henderson

Stephen E Henderson


According to the U.S. Constitution, the more you fly your drone, the more police can fly theirs. “Come on,” you might reply, “that hoary document”—and, yes, sorry to make you the sort who drops words like hoary—“that hoary document surely says nothing about drones.” But in fact it does. At least it does as interpreted by the courts. In particular, it is how they interpret the Fourth Amendment. So, to understand this aspect of drones, we first must understand this provision of the Bill of Rights...


Ou Professor: Fourth Amendment At Heart Of Dispute Between Fbi, Apple, Stephen E. Henderson Mar 2016

Ou Professor: Fourth Amendment At Heart Of Dispute Between Fbi, Apple, Stephen E. Henderson

Stephen E Henderson

The dispute between the FBI and Apple Inc. over the unlocking of the iPhone used by one of the San Bernadino shooters is important to all Americans. And so it's good that it is getting a wide airing. But when it comes to issues that have complicated tradeoffs, it can be important not just that we have the conversation, but that we use the right words. And here the debate deserves very mixed reviews. . . .


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 …


A Rose By Any Other Name: Regulating Law Enforcement Bulk Metadata Collection, Stephen E. Henderson Dec 2015

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

Stephen E Henderson

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 …


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 …

Regulating Drones Under The First And Fourth Amendments, Stephen E. Henderson, Joseph Thai, Marc Jonathan Blitz, James Grimsley Dec 2014

Regulating Drones Under The First And Fourth Amendments, Stephen E. Henderson, Joseph Thai, Marc Jonathan Blitz, James Grimsley

Stephen E Henderson

The FAA Modernization and Reform Act of 2012 requires the Federal Aviation Administration to integrate unmanned aerial vehicles (UAVs), or drones, into the national airspace system by September of this year. Yet perhaps because of their chilling accuracy in targeted killings abroad, perhaps because of an increasing consciousness of diminishing privacy more generally, and perhaps simply because of a fear of the unknown, divergent UAV-restrictive legislation has been proposed in Congress and enacted in a number of states. Ultimately, given UAV utility and cost effectiveness over a vast range of tasks, widespread commercial use seems certain. So it is imperative …


Immigration Surveillance, Anil Kalhan Nov 2014

Immigration Surveillance, Anil Kalhan

Anil Kalhan

In recent years, immigration enforcement levels have soared, yielding a widely noted increase in the number of noncitizens removed from the United States. Less visible, however, has been an attendant sea change in the underlying nature of immigration governance itself, hastened by new surveillance and dataveillance technologies. Like many other areas of contemporary governance, immigration control has rapidly become an information-centered and technology-driven enterprise. At virtually every stage of the process of migrating or traveling to, from, and within the United States, both noncitizens and U.S. citizens are now subject to collection and analysis of extensive quantities of personal information …


Light In The Darkness: How Leatpr Standards Guide Legislators In Regulating Law Enforcement Access To Cell Site Location Records, Susan Freiwald Jun 2014

Light In The Darkness: How Leatpr Standards Guide Legislators In Regulating Law Enforcement Access To Cell Site Location Records, Susan Freiwald

Susan Freiwald

This article measures the new ABA Standards for Criminal Justice: Law Enforcement Access to Third Party Records (LEATPR Standards) success by assessing the guidance they provide legislators interested in updating pertinent law regarding one specific type of data. Scholars should not expect the Standards to yield the same conclusions they would have furnished had they been able to draft a set of standards by themselves. The Standards emerged after years of painstaking consensus building and compromise no individual committee member got entirely what he wanted. Nonetheless, not every product of a committee turns out to have been worth the effort, …


Our Records Panopticon And The American Bar Association Standards For Criminal Justice, Stephen E. Henderson Dec 2013

Our Records Panopticon And The American Bar Association Standards For Criminal Justice, Stephen E. Henderson

Stephen E Henderson

"Secrets are lies. Sharing is caring. Privacy is theft." So concludes the main character in Dave Egger’s novel The Circle, in which a single company that unites Google, Facebook, and Twitter – and on steroids – has the ambition not only to know, but also to share, all of the world's information. It is telling that a current dystopian novel features not the government in the first instance, but instead a private third party that, through no act of overt coercion, knows so much about us. This is indeed the greatest risk to privacy in our day, both the unprecedented …


Reforming The Grand Jury To Protect Privacy In Third Party Records, Stephen E. Henderson, Andrew E. Taslitz Dec 2013

Reforming The Grand Jury To Protect Privacy In Third Party Records, Stephen E. Henderson, Andrew E. Taslitz

Stephen E Henderson

In late 2014, two grand juries returned controversial no bill decisions in police killings, one in Ferguson, Missouri, and one in New York City. These outcomes have renewed calls for grand jury reform, and whatever one thinks of these particular processes and outcomes, such reform is long overdue. One logical source of reform to better respect privacy in records, which would have incidental benefits beyond this privacy focus, would be the newly enacted American Bar Association Standards for Criminal Justice on Law Enforcement Access to Third Party Records (LEATPR).

But LEATPR exempts from its requirements access to records via a …


Immigration Policing And Federalism Through The Lens Of Technology, Surveillance, And Privacy, Anil Kalhan Nov 2013

Immigration Policing And Federalism Through The Lens Of Technology, Surveillance, And Privacy, Anil Kalhan

Anil Kalhan

With the deployment of technology, federal programs to enlist state and local police assistance with immigration enforcement are undergoing a sea change. For example, even as it forcefully has urged invalidation of Arizona’s S.B. 1070 and similar state laws, the Obama administration has presided over the largest expansion of state and local immigration policing in U.S. history with its implementation of the “Secure Communities” program, which integrates immigration and criminal history database systems in order to automatically ascertain the immigration status of every individual who is arrested and booked by state and local police nationwide. By 2012, over one fifth …


Who Should Be The ‘Decider’ On Keeping Our Secrets?, Stephen E. Henderson Sep 2013

Who Should Be The ‘Decider’ On Keeping Our Secrets?, Stephen E. Henderson

Stephen E Henderson

An invited essay for Constitution Day, also available here: http://blogs.law.widener.edu/constitution2013/2013-essay-authors/stephen-henderson/
It addresses the national security surveillance disclosed by Edward Snowden and others, and asks whether a fundamental shift would be prudent in the era of Big Data.


Addressing The Harm Of Total Surveillance: A Reply To Professor Neil Richards, Danielle Citron, David Gray Jun 2013

Addressing The Harm Of Total Surveillance: A Reply To Professor Neil Richards, Danielle Citron, David Gray

David C. Gray

In his insightful article The Dangers of Surveillance, 126 HARV. L. REV. 1934 (2013), Neil Richards offers a framework for evaluating the implications of government surveillance programs that is centered on protecting "intellectual privacy." Although we share his interest in recognizing and protecting privacy as a condition of personal and intellectual development, we worry in this essay that, as an organizing principle for policy, "intellectual privacy" is too narrow and politically fraught. Drawing on other work, we therefore recommend that judges, legislators, and executives focus instead on limiting the potential of surveillance technologies to effect programs of broad and indiscriminate …


The Davis Good Faith Rule And Getting Answers To The Questions Jones Left Open, Susan Freiwald Dec 2012

The Davis Good Faith Rule And Getting Answers To The Questions Jones Left Open, Susan Freiwald

Susan Freiwald

The Supreme Court’s decision in United States v. Jones clearly established that use of GPS tracking surveillance constitutes a search under the Fourth Amendment. But the Court left many other questions unanswered about the nature and scope of the constitutional privacy right in location data. A review of lower court decisions in the wake of Jones reveals that, rather than begin to answer the questions that Jones left open, courts are largely avoiding substantive Fourth Amendment analysis of location data privacy. Instead, they are finding that officers who engaged in GPS tracking and related surveillance operated in good faith, based …


A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David Gray, Danielle Citron Dec 2012

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David Gray, Danielle Citron

David C. Gray

On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and explores …

American Bar Association Criminal Justice Standards On Law Enforcement Access To Third Party Records, Stephen E. Henderson Dec 2012

American Bar Association Criminal Justice Standards On Law Enforcement Access To Third Party Records, Stephen E. Henderson

Stephen E Henderson

Drafted over the past six years and adopted by the American Bar Association (ABA) House of Delegates in February, 2012, these Criminal Justice Standards on Law Enforcement Access to Third Party Records provide much needed guidance to legislatures, courts, and administrative agencies having to decide how to regulate law enforcement access to existing records in the hands of third parties. It is the first framework of its kind, and it can do much to improve the current system of ad hoc protections in both state and federal systems. Decision makers are struggling to determine when to permit law enforcement access …


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 …


Real-Time And Historic Location Surveillance After United States V. Jones: An Administrable, Mildly Mosaic Approach, Stephen E. Henderson Dec 2012

Real-Time And Historic Location Surveillance After United States V. Jones: An Administrable, Mildly Mosaic Approach, Stephen E. Henderson

Stephen E Henderson

In United States v. Jones, the government took an extreme position: so far as the federal Constitution is concerned, law enforcement can surreptitiously electronically track the movements of any American over the course of an entire month without cause or restraint. According to the government, whether the surveillance be for good reason, invidious reason, or no reason, the Fourth Amendment is not implicated. Fortunately, that position was unanimously rejected by the High Court. The Court did not, however, resolve what restriction or restraint the Fourth Amendment places upon location surveillance, reflecting a proper judicial restraint in this nuanced and difficult …


After United States V. Jones, After The Fourth Amendment Third Party Doctrine, Stephen E. Henderson Dec 2012

After United States V. Jones, After The Fourth Amendment Third Party Doctrine, Stephen E. Henderson

Stephen E Henderson

In United States v. Jones, the Supreme Court unanimously rejected the proposition that the Government can surreptitiously electronically track vehicle location for an entire month without Fourth Amendment restraint. While the Court's three opinions leave much uncertain, in one perspective they fit nicely within a long string of cases in which the Court is cautiously developing new standards of Fourth Amendment protection, including a rejection of a strong third party doctrine. This Article develops that perspective and provides a cautiously optimistic view of where search and seizure protections may be headed.

More detail:

United States v. Jones, in which the …


What Alex Kozinski And The Investigation Of Earl Bradley Teach About Searching And Seizing Computers And The Dangers Of Inevitable Discovery, Stephen E. Henderson Dec 2012

What Alex Kozinski And The Investigation Of Earl Bradley Teach About Searching And Seizing Computers And The Dangers Of Inevitable Discovery, Stephen E. Henderson

Stephen E Henderson

This paper tells two stories. One concerns the investigation of a Delaware physician named Earl B. Bradley that resulted in a conviction and sentence of fourteen consecutive life terms for the sexual abuse of children. The other concerns the computer problems, both judicial and extra-judicial, of Chief Judge Alex Kozinski of the United States Court of Appeals for the Ninth Circuit. Though in a sense unrelated, they share lessons about the practicalities of computers and their search that are worth telling. As courts continue to struggle with how to cabin the searches of computers in order to minimize privacy intrusion …


Expectations Of Privacy In Social Media, Stephen E. Henderson Dec 2011

Expectations Of Privacy In Social Media, Stephen E. Henderson

Stephen E Henderson

This article, which largely tracks my remarks at Mississippi College’s Social Media Symposium, examines expectations of privacy in social media such as weblogs (blogs), Facebook pages, and Twitter tweets. Social media is diverse and ever-diversifying, and while I address some of that complexity, I focus on the core functionality, which provides the groundwork for further conversation as the technology and related social norms develop. As one would expect, just as with our offline communications and other online communications, in some we have an expectation of privacy that is recognized by current law, in some we have an expectation of privacy …


The Timely Demise Of The Fourth Amendment Third Party Doctrine, Stephen E. Henderson Dec 2010

The Timely Demise Of The Fourth Amendment Third Party Doctrine, Stephen E. Henderson

Stephen E Henderson

In what may be a slightly premature obituary, in this response to a forthcoming paper by Matthew Tokson I argue that the Fourth Amendment third party doctrine "has at least taken ill, and it can be hoped it is an illness from which it will never recover." It is increasingly unpopular as a matter of state constitutional law, has long been assailed in scholarship but now thoughtful alternatives are percolating, and it cannot – or at least should not – withstand the pressures which technology and social norms are placing upon it. Even the Supreme Court seems loath to defend …
