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 Modern Border: The Government Can Search . . . Anything?, Abigail Nusbaum

FIU Law Review

The evolution of modern technology has introduced new obstacles in interpreting the Fourth Amendment’s application to searches of peoples’ effects. Specifically, the longstanding exception to the Fourth Amendment permitting searches at the international border in the absence of probable cause does not so neatly apply to forensic searches of cell phones. Consequently, a circuit split has emerged on two aspects of the issue: the scope of the border exception and the requisite level of suspicion within that exception. The Supreme Court should find that forensic cell phone searches at the international border implicate Fourth Amendment privacy interests, requiring the border …

The Black Fourth Amendment, Charisma Hunter

Washington and Lee Law Review Online

Policing Black bodies serves at the forefront of the American policing system. Black bodies are subject to everlasting surveillance through institutions and everyday occurrences. From relaxing in a Starbucks to exercising, Black bodies are deemed criminals, surveilled, profiled, and subjected to perpetual implicit bias when participating in mundane activities. Black people should have the same protections as white people and should possess the ability to engage in everyday, commonplace, and routine activities.

The Fourth Amendment was not drafted with the intention of protecting Black bodies. In fact, Black bodies were considered three-fifths of a person at the drafting of the …

Kansas V. Glover And The Issue Of Reasonable Suspicion, Zach Kumar

Duke Journal of Constitutional Law & Public Policy Sidebar

It is settled law that an officer may initiate a traffic stop when there is articulable and reasonable suspicion that the person stopped has committed, is committing, or is about to commit a crime. In Kansas v. Glover, the Supreme Court has an opportunity to clarify what constitutes “reasonable suspicion.” The Court will determine whether it is reasonable for an officer to seize a vehicle if the registered owner has a revoked license and there is no information to suggest that the person driving is not the owner of the car. This Commentary argues that the Court should uphold …

State V. Nelson: Determining "Reasonable Suspicion" For Investigatory Stops In Maine, Sandra Denison Shannon

Maine Law Review

In 1994 the Maine Supreme Judicial Court, sitting as the Law Court, held in State v. Nelson that a police officer's observation of motorist Theodore Nelson consuming a single can of beer over a one-hour time period did not, by itself, give rise to a reasonable suspicion that Nelson thereafter illegally operated the vehicle under the influence of alcohol. This Note analyzes the Law Court's decision in Nelson. In its analysis, this Note compares Nelson to several other Maine opinions and recommends that, if the Maine Law Court is to continue to adhere to both objective and subjective standards in …

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 …

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 …

What's Fear Got To Do With It?: The "Armed And Dangerous" Requirement Of Terry, Gerald S. Reamey

Marquette Law Review

Rarely has a court’s opinion, even one from the Supreme Court of the United States, so altered existing notions of constitutional criminal procedure law as did the opinion in Terry v. Ohio. On several levels, the opinion dramatically shifted the way in which the Fourth Amendment was understood. Law students who had learned about the probable cause “requirement” and the warrant “requirement” were surprised to learn, especially in the case of the former, that these “requirements” were not required at all. To continue to conceptualize the Fourth Amendment’s single sentence guarantees as consisting of a “warrant clause” and a “reasonableness” …

Riley V. California: Privacy Still Matters, But How Much And In What Contexts?, Adam Lamparello, Charles E. Maclean

Adam Lamparello

Private information is no longer stored only in homes or other areas traditionally protected from warrantless intrusion. The private lives of many citizens are contained in digital devices no larger than the palm of their hand—and carried in public places. But that does not make the data within a cell phone any less private, just as the dialing of a phone number does not voluntarily waive an individual’s right to keep their call log or location private. Remember that we are not talking exclusively about individuals suspected of committing violent crimes. The Government is recording the calls and locations of …

Brief Of Amici Curiae -- Heien V. State Of North Carolina, Charles E. Maclean, Adam Lamparello

Adam Lamparello

Reasonable suspicion of unlawful activity cannot be predicated on conduct that does not violate the law. Put differently, if reasonableness — or reasonable suspicion — is to mean anything, it means that apparent violations of the law must be based on actual violations of the law. The North Carolina Supreme Court’s decision sends a message to drivers throughout the country that they cannot be wrong about what the law requires, even where law enforcement is wrong — dead wrong — about what the law proscribes.

Nuance, Technology, And The Fourth Amendment: A Response To Predictive Policing And Reasonable Suspicion, Fabio Arcila Jr.

Scholarly Works

In an engaging critique, Professor Arcila finds that Professor Ferguson is correct in that predictive policing will likely be incorporated into Fourth Amendment law and that it will alter reasonable suspicion determinations. But Professor Arcila also argues that the potential incorporation of predictive policing reflects a larger deficiency in our Fourth Amendment jurisprudence and that it should not be adopted because it fails to adequately consider and respect a broader range of protected interests.

Predictive Policing And Reasonable Suspicion, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

Predictive policing is a new law enforcement strategy to reduce crime by predicting criminal activity before it happens. Using sophisticated computer algorithms to forecast future events from past crime patterns, predictive policing has become the centerpiece of a new smart-policing strategy in several major cities. The initial results have been strikingly successful in reducing crime.This article addresses the Fourth Amendment consequences of this police innovation, analyzing the effect of predictive policing on the concept of reasonable suspicion. This article examines predictive policing in the context of the larger constitutional framework of “prediction” and the Fourth Amendment. Many aspects of current …

Immigration And National Security: The Illusion Of Safety Through Local Law Enforcement Action, David A. Harris

Articles

Despite efforts to reform immigration law in the 1980s and the 1990s, the new laws passed in those decades by the Congress did not solve the long-term problems raised by undocumented people entering the United States. The issue arose anew after the terrorist attacks of September, 2001. While the advocates for immigration crackdowns in the 1980s and 1990s had cast the issue as one of economics and cultural transformation, immigration opponents after 9/11 painted a different picture: illegal immigration, they said, was a national security issue. If poor farmers from Mexico and Central America could sneak into the U.S. across …

Probability, Probable Cause, And The Law Of Unintended Consequences, Lawrence Rosenthal

Lawrence Rosenthal

This brief essay responds to Max Minzer's article "Putting Probability Back into Probable Cause." The essay supports Professor Minzer's proposal for the use of empirical evidence of the success of a given investigating officer or investigative technique in assessing the existence of probable cause to search or seize, but offers a caveat. If an officer's "hit rate" becomes central to Fourth Amendment analysis, there is a serious danger of overdeterrence which, in turn, could lead to a dangerous escalation in violent crime. The essay offers some proposals for minimizing the risk of overdeterrence in an empirically-based regime of probable cause.

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 …

Payton, Practical Wisdom, And The Pragmatist Judge: Is Payton's Goal To Prevent Unreasonable Entries Or To Effectuate Home Arrests?, Christos Papapetrou

Fordham Urban Law Journal

This Comment analyzes the conflicting "objective" and "subjective" tests that courts use to determine if a law enforcement officer's entry into a suspect's home is valid following the Supreme Court's holding in Payton v. New York that an arrest warrant implicitly carries with it a right to enter a suspect's home when there is "reason to believe" it is the suspect's residence and that the suspect is inside. The Comment questions how courts should interpret the "reason to believe" standard and analyzes an approach put forth by Professor Matthew A. Edwards in his article, Posner's Pragmatism and Payton Home Arrests. …
