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 …

Filling The Potholes Of Pretextual Traffic Stops: A Better Road Forward For Ohio, Jordan Weeks

Cleveland State Law Review

The Fourth Amendment was one of the driving forces behind the United States Revolution. This Amendment generally protects individuals against “unreasonable” searches and seizures. But what does “reasonable” mean in the context of a traffic stop?

In 1996, the U.S. Supreme Court in Whren v. United States tried answering this question. In so doing, the Court determined that pretextual traffic stops are “reasonable.” Pretextual traffic stops occur where an officer stops a vehicle and cites a lawful reason for the stop, yet the underlying reason is unlawful. The Whren Court determined that an officer’s intent is completely irrelevant to whether …

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 …

Revising Reasonableness In The Cloud, Ian Walsh

Washington Law Review

Save everything—just in case––and search for it later. This is a modern mantra fueled by the ubiquity of smartphones, laptops, tablets, and free or low-cost data storage that leads users to store massive amounts of data in the cloud. But when users trust third-party cloud storage providers with private communications, they also surrender Fourth Amendment constitutional certainty. Existing statutory safeguards for these communications are lower than Fourth Amendment warrant and probable cause standards; this permits the government to seize large quantities of users’ private communications stored in the cloud with only minimal justification. Due to the revealing nature of such …

Suspects, Cars & Police Dogs: A Complicated Relationship, Brian R. Gallini

Washington Law Review

Officers are searching and arresting vehicle occupants without a warrant with increasing regularity. For justification, this Article demonstrates, lower courts across the country unconstitutionally expand the scope of the Fourth Amendment’s automobile exception—often in the context of a positive dog alert. But Supreme Court jurisprudence specifically limits the scope of the automobile exception to warrantless searches of cars and their containers. In other words, the probable cause underlying the automobile exception allows police to search a vehicle and its containers—nothing more.

Despite that clear guidance, this Article argues that a growing number of lower courts nationwide unconstitutionally rely on the …

Limited Privacy In “Pings:” Why Law Enforcement’S Use Of Cell-Site Simulators Does Not Categorically Violate The Fourth Amendment, Lara M. Mcmahon

Washington and Lee Law Review

This Note proposes four factors courts should consider when asked to determine whether law enforcement’s use of a cell-site simulator constituted a Fourth Amendment search. The first asks courts to consider whether the cell-site simulator surveillance infringed on a constitutionally protected area, such as the home. The second asks courts to consider the duration of the cell-site simulator surveillance. The third asks courts to consider whether the cell-site simulator surveillance was conducted actively or passively. The fourth asks courts to focus on the nature and depth of the information obtained as a result of the cell-site simulator surveillance. If, after …

State V. Pinkham: Erosion Of Meaningful Forth Amendment Protection For Vehicle Stops In Maine?, Roger M. Clement Jr.

Maine Law Review

In State v. Pinkham, the Maine Supreme Judicial Court, sitting as the Law Court, held that a police officer's stop of a motorist to inquire and advise about the motorist's improper-but not illegal-lane usage did not necessarily violate the Fourth Amendment's proscription against unreasonable seizures. The Pinkham decision is the first time that the Law Court has validated the stop of a moving vehicle in the absence of either a suspected violation of law or an imminent, ongoing threat to highway safety.
This Note considers whether the Law Court was correct in sustaining the police officer's stop of Ronald Pinkham. …

Please Stop: The Law Court's Recent Roadblock Decisions, Jonathan A. Block

Maine Law Review

Police checkpoints or “roadblocks” have become an increasingly utilized law enforcement tool. At best, these checkpoints result in only a minor inconvenience to motorists. When abused, however, roadblocks have the potential for invidious invasions of privacy and personal freedom. Roadblocks are designed to deter, and to a lesser extent detect, criminal activity by stopping everyone—both the guilty and the law-abiding—for a brief inspection, thereby impinging to some degree on one's freedom of travel, privacy, and “right to be let alone.” Such “seizures” must be “reasonable” under the Fourth Amendment in order to survive constitutional challenge. The major difference between roadblocks …

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 …

Fourth Amendment Gloss, Aziz Z. Huq

Northwestern University Law Review

Conventional wisdom suggests that a constitutional right should be defined so as to effectively constrain government actors. A right defined in terms of what state actors routinely do would seem to impose in practice an ineffectual brake on much intrusive state action—and so seems pointless. Nevertheless, in defining Fourth Amendment rights, the Supreme Court frequently draws on the practice of contemporaneous government actors to define the constitutional floor for police action. The actions of the regulated thus define the content of regulation. This Article isolates and analyzes this seemingly paradoxical judicial practice, which it labels “Fourth Amendment gloss,” by analogy …

Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

Standing Under State Search And Seizure Provision: Why The Minnesota Supreme Court Should Have Rejected The Federal Standards And Instead Invoked Greater Protection Under Its Own Constitution In State V. Carter, Rebecca C. Garrett

Maine Law Review

In State v. Carter, the Minnesota Supreme Court considered whether a criminal defendant had “standing” to challenge an alleged search under the Fourth Amendment and Article 1, Section 10 of the Minnesota Constitution. The defendant moved to suppress evidence obtained by a police officer who had peered in the window of an apartment where the defendant was participating in a drug-packaging operation with the apartment's leaseholder. A divided court held that the defendant had a legitimate expectation of privacy in the apartment. Therefore, the defendant had standing to challenge the legality of the police officer's observations pursuant to the Fourth …

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 …

Does The End Justify The Means? The Clumsy And Circuitous Logic Of Blood Test Admissibility In Criminal Prosecutions In State V. Cormier, Kyle T. Macdonald

Maine Law Review

In State v. Cormier, the Maine Supreme Judicial Court, sitting as the Law Court, was asked to determine whether a Maine statute requiring law enforcement officers to test the blood of all drivers for intoxicants following a fatal motor vehicle collision violates the Fourth Amendment of the United States Constitution when the operation of the statute allows for the admission of those blood test results in a future criminal trial of the driver. In determining that the procedures of title 29-A, section 2522 of the Maine Revised Statutes are not violative of the Fourth Amendment, the Law Court effectively confirmed …

The Private Search Doctrine And The Evolution Of Fourth Amendment Jurisprudence In The Face Of New Technology: A Broad Or Narrow Exception?, Adam A. Bereston

Catholic University Law Review

The advent of new technology has presented courts with unique challenges when analyzing searches and seizures under the Fourth Amendment. Out of necessity, the application of the Fourth Amendment has evolved to address privacy issues stemming from modern technology that could not have been anticipated by the Amendment’s drafters. As part of this evolution, the Supreme Court devised the “private search” doctrine, which upholds the constitutionality of warrantless police searches of items that were previously searched by a private party, so long as the police search does not exceed the scope of the private-party search. However, courts have struggled to …

Liberty At The Cost Of Constitutional Protections: Undocumented Immigrants And Fourth Amendment Rights, Linet Suárez

University of Miami Inter-American Law Review

The Supreme Court has issued many opinions indirectly addressing the Fourth amendment rights of undocumented immigrants. However, none of these opinions answer the questions that matter most: do undocumented immigrants have Fourth Amendment protections and if so, what are they. These questions have increasingly become more important because advances in technology facilitate intrusive searches and seizures by law enforcement officers. This article will specifically focus on the Department of Homeland Security and its use of GPS ankle bracelets to monitor undocumented immigrants. This article compares existing Supreme Court opinions concerning undocumented immigrants and Fourth Amendment rights in the technological age. …

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 …

Cell Phone Searches After Riley: Establishing Probable Cause And Applying Search Warrant Exceptions, Erica L. Danielsen

Pace Law Review

Part I of this note discusses the Fourth Amendment’s protection against unreasonable search and seizures and its probable cause requirement. The Fourth Amendment’s text remains the same since its enactment. However, interpretation of the Fourth Amendment continues to evolve in order to stay current with society. Interpretation of the Fourth Amendment also varies based on state constitutional law since states can provide its citizens with greater protection than the United States Constitution. This is why the United States Supreme Court, federal district courts, and state courts have all undergone thorough Fourth Amendment analyses when applying the true meaning of the …

Policing In The Era Of Permissiveness: Mitigating Misconduct Through Third-Party Standing, Julian A. Cook Iii

Brooklyn Law Review

On April 4, 2015, Walter L. Scott was driving his vehicle when he was stopped by Officer Michael T. Slager of the North Charleston, South Carolina, police department for a broken taillight. A dash cam video from the officer’s vehicle showed the two men engaged in what appeared to be a rather routine verbal exchange. Sometime after Slager returned to his vehicle, Scott exited his car and ran away from Slager, prompting the officer to pursue him on foot. After he caught up with Scott in a grassy field near a muffler establishment, a scuffle between the men ensued, purportedly …

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 …

Search And Seizure - Warrantless Search- Allowable Extent Incident To Arrest; United States V. Robinson, John Nelson Childs

Akron Law Review

DISTRICT OF COLUMBIA Metropolitan Policeman Richard Jencks, on April 19, 1968, halted Willie Robinson for a "routine spot check."' While examining Robinson's driver's license, motor vehicle registration, and selective service card, Officer Jencks noticed an 11-year discrepancy between the two birthdates listed on his driver's license and his draft card. Upon a later check of police traffic records, Officer Jencks discovered that an operator's permit issued to "Willie Robinson, Jr.," born in 1927, had been revoked and that a temporary license had been issued to a "Willie Robinson," born in 1938. Four days later, the same officer observed Robinson operating …
