Computationally Assessing Suspicion, Wesley M. Oliver

Law Faculty Publications

Law enforcement officers performing drug interdiction on interstate highways have to decide nearly every day whether there is reasonable suspicion to detain motorists until a trained dog can sniff for the presence of drugs. The officers’ assessments are often wrong, however, and lead to unnecessary detentions of innocent persons and the suppression of drugs found on guilty ones. We propose a computational method of evaluating suspicion in these encounters and offer experimental results from early efforts demonstrating its feasibility. With the assistance of large language and predictive machine learning models, it appears that judges, advocates, and even police officers could …

The Fourth Amendment's Constitutional Home, Gerald S. Dickinson

Articles

The home enjoys omnipresent status in American constitutional law. The Bill of Rights, peculiarly, has served as the central refuge for special protections to the home. This constitutional sanctuary has elicited an intriguing textual and doctrinal puzzle. A distinct thread has emerged that runs through the first five amendments delineating the home as a zone where rights emanating from speech, smut, gods, guns, soldiers, searches, sex, and self-incrimination enjoy special protections. However, the thread inexplicably unravels upon arriving at takings. There, the constitutional text omits and the Supreme Court’s doctrine excludes a special zone of safeguards to the home. This …

Cops And Cars: How The Automobile Drove Fourth Amendment Law, Tracey Maclin

Faculty Scholarship

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

Unlocking The Fifth Amendment: Passwords And Encrypted Devices, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Each year, law enforcement seizes thousands of electronic devices — smartphones, laptops, and notebooks — that it cannot open without the suspect’s password. Without this password, the information on the device sits completely scrambled behind a wall of encryption. Sometimes agents will be able to obtain the information by hacking, discovering copies of data on the cloud, or obtaining the password voluntarily from the suspects themselves. But when they cannot, may the government compel suspects to disclose or enter their password?

This Article considers the Fifth Amendment protection against compelled disclosures of passwords — a question that has split and …

The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This excerpt from the recently published Shadow Vigilantes book argues that, while vigilantism, even moral vigilantism, can be dangerous to a society, the real danger is not of hordes of citizens, frustrated by the system’s doctrines of disillusionment, rising up to take the law into their own hands. Frustration can spark a vigilante impulse, but such classic aggressive vigilantism is not the typical response. More common is the expression of disillusionment in less brazen ways by a more surreptitious undermining and distortion of the operation of the criminal justice system.

Shadow vigilantes, as they might be called, can affect the …

The 2016 Amendments To Criminal Rule 41: National Search Warrants To Seize Cyberspace, “Particularly” Speaking, Devin M. Adams

Law Student Publications

George Orwell's dystopia, with the ever-watchful Big Brother, has seemingly become a reality with the recently passed amendments to Rule 41 of the Federal Rules of Criminal Procedure. Rule 41, governing searches and seizures, now permits magistrate judges to authorize agents- under a single warrant- to "remotely access," and simultaneously search, copy and seize information from an infinite number of unknown electronic devices in multiple districts anywhere in the country. The unlimited jurisdiction provision is triggered when a device's location is obscured through "technological means," or if agents are investigating computer crimes in five or more districts- regardless of whether …

Justice Scalia’S Originalism And Formalism: The Rule Of Criminal Law As A Law Of Rules, Stephanos Bibas

All Faculty Scholarship

Far too many reporters and pundits collapse law into politics, assuming that the left–right divide between Democratic and Republican appointees neatly explains politically liberal versus politically conservative outcomes at the Supreme Court. The late Justice Antonin Scalia defied such caricatures. His consistent judicial philosophy made him the leading exponent of originalism, textualism, and formalism in American law, and over the course of his three decades on the Court, he changed the terms of judicial debate. Now, as a result, supporters and critics alike start with the plain meaning of the statutory or constitutional text rather than loose appeals to legislative …

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 …

Probable Cause And Reasonable Suspicion: Totality Tests Or Rigid Rules?, Kit Kinports

Journal Articles

This piece argues that the Supreme Court's April 2014 decision in Navarette v. Calfornia, like last Term's opinion in Florida v. Harris, deviates from longstanding Supreme Court precedent treating probable cause and reasonable suspicion as totality-of-the-circumstances tests. Instead, these two recent rulings essentially rely on rigid rules to define probable cause and reasonable suspicion. The article criticizes the Court for selectively endorsing bright-line tests that favor the prosecution, and argues that both decisions generate rules that oversimplify and therefore tend to be overinclusive.

The Law And Economics Of Stop-And-Frisk, David S. Abrams

All Faculty Scholarship

The relevant economic and legal research relating to police use of stop-and-frisk has largely been distinct. There is much to be gained by taking an interdisciplinary approach. This Essay emphasizes some of the challenges faced by those seeking to evaluate the efficacy and legality of stop-and-frisk, and suggests some ways forward and areas of exploration for future research.

The Dog Days Fourth Amendment Jurisprudence, Kit Kinports

Journal Articles

This Article discusses Florida v. Harris and Florida v. Jardines, the two Fourth Amendment drug dog opinions issued by the Supreme Court earlier this year. Together the cases hold that a narcotics detection dog effects a “search” when it intrudes on a constitutionally protected area in order to collect evidence, but that the dog’s positive alert is generally sufficient to support a finding of probable cause. The piece argues that both cases essentially generate a bright-line rule, thereby deviating from precedent that favored a more amorphous standard considering all the surrounding circumstances. Like many purportedly clear rules, the ones …

Mapp V. Ohio Revisited: A Law Clerk's Diary, Polly J. Price

Faculty Articles

The 1960 Supreme Court Term laid the groundwork for the subsequent revolution in the relationship between state and federal law accomplished by the Supreme Court under Chief Justice Earl Warren. The "most famous search and seizure case in American history" - Mapp v. Ohio - would be decided that Term. Mapp held that the Fourth Amendment's protection against "unreasonable searches and seizures" required the exclusion of evidence found through an illegal search by state and local police officers, extending to the states a rule that had previously applied only to federal law enforcement. Mapp became a pivotal chapter in the …

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 …

Criminal Procedure In Perspective, Kit Kinports

Journal Articles

This Article attempts to situate the Supreme Court's constitutional criminal procedure jurisprudence in the academic debates surrounding the reasonable person standard, in particular, the extent to which objective standards should incorporate a particular individual's subjective characteristics. Analyzing the Supreme Court's search and seizure and confessions opinions, I find that the Court shifts opportunistically from case to case between subjective and objective tests, and between whose point of view - the police officer's or the defendant's - it views as controlling. Moreover, these deviations cannot be explained either by the principles the Court claims underlie the various constitutional provisions at issue …

Bearing False Witness: Perjured Affidavits And The Fourth Amendment, Stephen W. Gard

Law Faculty Articles and Essays

The purpose of this Article is to articulate appropriate legal doctrine to govern the problem of false statements of fact by law enforcement officers in warrant affidavits. This Article addresses the issue in the context of actions brought pursuant to 42 U.S.C. § 1983 to redress such Fourth Amendment violations. This perspective promises to be interesting and unique for two reasons. First, the fact that the guilty are ordinarily the direct beneficiaries of the Fourth Amendment has long been a matter of grave concern. In contrast, rarely, if ever, will anyone except an innocent victim of a search based on …

In The Trenches: Searches And The Misunderstood Common-Law History Of Suspicion And Probable Cause, Fabio Arcila

Scholarly Works

A detailed analysis of the common law during the Framers’ era, and of how it reflected the Fourth Amendment’s restrictions, shows that many judges believed they could issue search warrants without independently assessing the adequacy of probable cause, and that this view persisted even after the Fourth Amendment became effective. This conclusion challenges the leading originalist account of the Fourth Amendment, which Professor Thomas Davies published in the Michigan Law Review in 1999.

Learned treatises in particular, and to a lesser extent a few case decisions, had articulated a judicial duty to monitor probable cause. But it is a mistake …

A Response To Professor Steinberg’S Fourth Amendment Chutzpah, Fabio Arcila

Scholarly Works

Professor David Steinberg believes that the Fourth Amendment was intended only to provide some protection against physical searches of homes through imposition of a specific warrant requirement because the Framers' only object in promulgating the Fourth Amendment was to ban physical searches of homes under general warrants or no warrants at all. This response essay takes issue with his thesis by (1) discussing its implications, (2) reviewing some concerns with his methodology in reviewing the historical record, and (3) examining the theoretical implication underlying his thesis that, except as to homes, we have a majoritarian Fourth Amendment, and questioning whether …

Reflections On Standing: Challenges To Searches And Seizures In A High Technology World, José F. Anderson

All Faculty Scholarship

Among the profound issues that surround constitutional criminal procedure is the obscure often overlooked issue of who has standing to challenge an illegal search, seizure or confession. Privacy interests are often overlooked because without a legal status that allows a person to complain in court, there is no way to challenge whether one is constitutionally protected from personal invasions. Standing is that procedural barrier often imposed to prevent a person in a case from objecting to improper police conduct because of his or her relationship of ownership, proximity, location, or interest in an item searched or a thing seized. Although …

The Fourth Amendment And Terrorism, John Burkoff

The important questions we need to ask and to answer B in the perilous times in which we live B is whether the Fourth Amendment applies in the same fashion not just to run of the mill criminals, but also to terrorists and suspected terrorists, individuals who are committing or who have committed B or who may be poised to commit B acts aimed at the destruction of extremely large numbers of people? Professor Burkoff argues that we can protect ourselves from cataclysmic threats of this sort and still maintain a fair and objective application of Fourth Amendment doctrine that …

Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith

Journal Articles

Over the past decade, law enforcement authorities have amassed huge collections of DNA samples and the identifying profiles derived from them. Large DNA databanks routinely help to identify the guilty and to exonerate the innocent, but as the databanks grow, so do fears about civil liberties. Perhaps the most controversial policy issue in the creation of these databases is the question of coverage: Whose DNA profiles should be stored in them? The possibilities extend from convicted violent sex offenders to all convicted felons, to everyone arrested, to the entire population. This Article questions the rationales for drawing the line at …
