The Automated Fourth Amendment, Maneka Sinha

Faculty Scholarship

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible. Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

Requiring What’S Not Required: Circuit Courts Are Disregarding Supreme Court Precedent And Revisiting Officer Inadvertence In Cyberlaw Cases, Michelle Zakarin

Scholarly Works

As the age of technology has taken this country by surprise and left us with an inability to formally prepare our legal system to incorporate these advances, many courts are forced to adapt by applying pre-technology rules to new technological scenarios. One illustration is the plain view exception to the Fourth Amendment. Recently, the issue of officer inadvertence at the time of the search, a rule that the United States Supreme Court has specifically stated is not required in plain view inquiries, has been revisited in cyber law cases. It could be said that the courts interested in the existence …

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 …

The Fourth Amendment Inventory As A Check On Digital Searches, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Police and federal agents generally must obtain a warrant to search the tens of thousands of devices they seize each year. But once they have a warrant, courts afford these officers broad leeway to search the entire device, every file and folder, all metadata and deleted data, even if in search of only one incriminating file. Courts avow great reverence for the privacy of personal information under the Fourth Amendment but then claim there is no way to limit where an officer might find the target files, or know where the suspect may have hidden them.

These courts have a …

Why Courts Fail To Protect Privacy: Race, Age, Bias, And Technology, Bernard Chao, Catherine Durso, Ian Farrell, Christopher Robertson

Sturm College of Law: Faculty Scholarship

The Fourth Amendment protects against unreasonable “searches and seizures,” but in the digital age of stingray devices and IP tracking, what constitutes a search or seizure? The Supreme Court has held that the threshold question depends on and reflects the “reasonable expectations” of ordinary members of the public concerning their own privacy. For example, the police now exploit the “third party” doctrine to access data held by email and cell phone providers, without securing a warrant, on the Supreme Court’s intuition that the public has no expectation of privacy in that information. Is that assumption correct? If judges’ intuitions about …

Terry Stops And Frisks: The Troubling Use Of Common Sense In A World Of Empirical Data, David A. Harris, David Rudovsky

Articles

The investigative detention doctrine first announced in Terry v. Ohio and amplified over the past fifty years has been much analyzed, praised, and criticized from a number of perspectives. Significantly, however, over this time period commentators have only occasionally questioned the Supreme Court’s “common sense” judgments regarding the factors sufficient to establish reasonable suspicion for stops and frisks. For years, the Court has provided no empirical basis for its judgments, due in large part to the lack of reliable data. Now, with the emergence of comprehensive data on these police practices, much can be learned about the predictive power of …

Notice And Standing In The Fourth Amendment: Searches Of Personal Data, Jennifer Daskal

Articles in Law Reviews & Other Academic Journals

In at least two recent cases, courts have rejected service providers' capacity to raise Fourth Amendment claims on behalf of their customers. These holdings rely on longstanding Supreme Court doctrine establishing a general rule against third parties asserting the Fourth Amendment rights of others. However, there is a key difference between these two recent cases and those cases on which the doctrine rests. The relevant Supreme Court doctrine stems from situations in which someone could take action to raise the Fourth Amendment claim, even if the particular thirdparty litigant could not. In the situations presented by the recent cases, by …

Riley V. California And The Beginning Of The End For The Third-Party Search Doctrine, David A. Harris

Articles

In Riley v. California, the Supreme Court decided that when police officers seize a smart phone, they may not search through its contents -- the data found by looking into the call records, calendars, pictures and so forth in the phone -- without a warrant. In the course of the decision, the Court said that the rule applied not just to data that was physically stored on the device, but also to data stored "in the cloud" -- in remote sites -- but accessed through the device. This piece of the decision may, at last, allow a re-examination of …

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 …

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 …

Using The Dna Testing Of Arrestees To Reevaluate Fourth Amendment Doctrine, Steven P. Grossman

All Faculty Scholarship

With the advent of DNA testing, numerous issues have arisen with regard to obtaining and using evidence developed from such testing. As courts have come to regard DNA testing as a reliable method for linking some people to crimes and for exonerating others, these issues are especially significant. The federal government and most states have enacted statutes that permit or direct the testing of those convicted of at least certain crimes. Courts have almost universally approved such testing, rejecting arguments that obtaining and using such evidence violates the Fourth Amendment.

More recently governments have enacted laws permitting or directing the …

Anti-Justice, Melanie D. Wilson

Scholarly Articles

This Article contends that, despite their unique, ethical duty to “seek justice,” prosecutors regularly fail to fulfill this ethical norm when removed from the traditional, adversarial courtroom setting. Examples abound. For instance, in 2013, Edward Snowden leaked classified information revealing a government-operated surveillance program known as PRISM. That program allows the federal government to collect metadata from phone companies and email accounts and to monitor phone conversations. Until recently, prosecutors relied on some of this covertly acquired intelligence to build criminal cases against American citizens without informing the accused. In failing to notify defendants, prosecutors violated the explicit statutory directives …

On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye

Journal Articles

For nearly a decade, DNA-on-arrest laws eluded scrutiny in the courts. For another five years, they withstood a gathering storm of constitutional challenges. In Maryland v. King, however, Maryland's highest court reasoned that usually fingerprints provide everything police need to establish the true identity of an individual before trial and that the state's interest in finding the perpetrators of crimes by trawling databases of DNA profiles is too "generalized" to support "a warrantless, suspicionless search." The U.S. Supreme Court reacted forcefully. Chief Justice Roberts stayed the Maryland judgment, writing that "given the considered analysis of courts on the other side …

Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye

Journal Articles

In Maryland v. King, the Supreme Court applied a balancing test to uphold a Maryland statute mandating preconviction collection and analysis of DNA from individuals charged with certain crimes. The DNA profiles are limited to an inherited set of DNA sequences that are not known to be functional and that are tokens of individual identity. This invited online essay examines two aspects of an article on the case by Professor Erin Murphy. I question the claim that the case is pivotal in a conceivable abandonment of the per se rule that warrantless, suspicionless searches are unconstitutional unless they fall …

Genetic Privacy And The Fourth Amendment: Unregulated Surreptitious Dna Harvesting, Albert E. Scherr

Law Faculty Scholarship

Genetic privacy and police practices have come to the fore in the criminal justice system. Case law and stories in the media document that police are surreptitiously harvesting the DNA of putative suspects. Some sources even indicate that surreptitious data banking may also be in its infancy. Surreptitious harvesting of out-of-body DNA by the police is currently unregulated by the Fourth Amendment. The few courts that have addressed the issue find that the police are free to harvest DNA abandoned by a putative suspect in a public place. Little in the nascent surreptitious harvesting case law suggests that surreptitious data …

The Rise, Decline And Fall(?) Of Miranda, Yale Kamisar

Articles

There has been a good deal of talk lately to the effect that Miranda1 is dead or dying-or might as well be dead.2 Even liberals have indicated that the death of Miranda might not be a bad thing. This brings to mind a saying by G.K. Chesterton: "Don't ever take a fence down until you know the reason why it was put up."4

A Parent's "Apparent" Authority: Why Intergenerational Coresidence Requires A Reassessment Of Parental Consent To Search Adult Children's Bedrooms, Hillary B. Farber

Faculty Publications

The proliferation of multigenerational U.S. households provides a new perspective on the social customs and practices concerning coresidence in the United States. Rather than relying outdated presumptions of parental control, this Article argues that police should be compelled to conduct a more thorough inquiry before searching areas occupied exclusively by the adult child. Police should differentiate between "common" and private areas, and inquire into any agreements - formal or informal - that the parent and child may have regarding access and control over such areas. By fully recognizing the changing nature of the American household and rejecting a bare reliance …

Unraveling The Exclusionary Rule: From Leon To Herring To Robinson - And Back?, David H. Kaye

Journal Articles

The Fourth Amendment exclusionary rule began to unravel in United States v. Leon. The facts were compelling. Why exclude reliable physical evidence from trial when it was not the constable who blundered, but “a detached and neutral magistrate” who misjudged whether probable cause was present and issued a search warrant? Later cases applied the exception for “good faith” mistakes to a police officer who, pursuing a grudge against a suspect, arrested and searched him and his truck on the basis of a false and negligent report from a clerk in another county of an outstand­ing arrest warrant. The California Supreme …

Dna Database Trawls And The Definition Of A Search In Boroian V. Mueller, David H. Kaye

Journal Articles

As a general matter, once the government acquires information from a permissible search or seizure, it can use this information in later criminal investigations. Courts have applied this simple rule to uphold the indefinite reuse of DNA samples acquired from convicted offenders. This essay describes the First Circuit Court of Appeals’ reliance on the rule in rejecting a convicted offender’s claim that his DNA sample and profile had to be removed from the federal DNA databank after he completed his sentence. Acknowledging that the rule permitting reuse should not be applied mechanically, I argue that the rule's application to DNA …

When Machines Are Watching: How Warrantless Use Of Gps Surveillance Technology Violates The Fourth Amendment Right Against Unreasonable Searches, David Thaw, Priscilla Smith, Nabiha Syed, Albert Wong

Articles

Federal and state law enforcement officials throughout the nation are currently using Global Positioning System (GPS) technology for automated, prolonged surveillance without obtaining warrants. As a result, cases are proliferating in which criminal defendants are challenging law enforcement’s warrantless uses of GPS surveillance technology, and courts are looking for direction from the Supreme Court. Most recently, a split has emerged between the Ninth and D.C. Circuit Courts of Appeal on the issue. In United States v. Pineda-Moreno, the Ninth Circuit relied on United States v. Knotts — which approved the limited use of beeper technology without a warrant — to …

Hanging On By A Thread: The Exclusionary Rule (Or What's Left Of It) Lives For Another Day, David A. Moran

Articles

Back when there was a Soviet Union, foreign intelligence officers would anxiously await the May Day parade in Moscow to see who would be standing next to the chairman of the Communist Party and who would be missing from the reviewing platform altogether. Since the Soviet government and the statecontrolled press published very little about what was really going on in the halls of state power, this was considered the most reliable way to determine who was in or out of favor and, by extension, how the domestic and foreign policies of the world's second most powerful country were likely …

Picture This: Body Worn Video Devices ('Head Cams') As Tools For Ensuring Fourth Amendment Compliance By Police, David A. Harris

Articles

A new technology has emerged with the potential to increase police compliance with the law and to increase officers’ accountability for their conduct. Called “body worn video” (BWV) or “head cams,” these devices are smaller, lighter versions of the video and audio recording systems mounted on the dash boards of police cars. These systems are small enough that they consist of something the size and shape of a cellular telephone earpiece, and are worn by police officers the same way. Recordings are downloaded directly from the device into a central computer system for storage and indexing, which protects them from …

How Accountability-Based Policing Can Reinforce - Or Replace - The Fourth Amendment Exclusionary Rule, David A. Harris

Articles

In Hudson v. Michigan, a knock-and-announce case, Justice Scalia's majority opinion came close to jettisoning the Fourth Amendment exclusionary rule. The immense costs of the rule, Scalia said, outweigh whatever benefits might come from it. Moreover, police officers and police departments now generally follow the dictates of the Fourth Amendment, so the exclusionary rule has outlived the reasons that the Court adopted it in the first place. This viewpoint did not become the law because Justice Kennedy, one member of the five-vote majority, withheld his support from this section of the opinion. But the closeness of the vote on …

The 'High Crime Area' Question: Requiring Verifiable And Quantifiable Evidence For Fourth Amendment Reasonable Suspicion Analysis, Andrew Ferguson, Damien Bernache

Articles in Law Reviews & Other Academic Journals

This article proposes a legal framework to analyze the "high crime area" concept in Fourth Amendment reasonable suspicion challenges.Under existing Supreme Court precedent, reviewing courts are allowed to consider that an area is a "high crime area" as a factor to evaluate the reasonableness of a Fourth Amendment stop. See Illinois v. Wardlow, 528 U.S. 119 (2000). However, the Supreme Court has never defined a "high crime area" and lower courts have not reached consensus on a definition. There is no agreement on what a "high-crime area" is, whether it has geographic boundaries, whether it changes over time, whether it …

Waiting For The Other Shoe: Hudson And The Precarious State Of Mapp, David A. Moran

Articles

I have no idea whether my death will be noted in the New York Times. But if it is, I fear the headline of my obituary will look something like: "Professor Dies; Lost Hudson v. Michigan' in Supreme Court, Leading to Abolition of Exclusionary Rule." The very existence of this Symposium panel shows, I think, that my fear is well-grounded. On the other hand, I am not quite as fearful that Hudson foreshadows the complete overruling of Mapp v. Ohio2 and Weeks v. United States3 as I was when I published an article just three months after the Hudson decision …
