Computationally Assessing Suspicion, Wesley M. Oliver, Morgan A. Gray, Jaromir Savelka, Kevin D. Ashley

University of Cincinnati Law Review

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 Post-Dobbs Reality: Privacy Expectations For Period-Tracking Apps In Criminal Abortion Prosecutions, Sophie L. Nelson

Pepperdine Law Review

The Supreme Court’s decision to overturn Roe v. Wade and Planned Parenthood v. Casey in June 2022 was met with waves of both support and criticism throughout the United States. Several states immediately implemented or began drafting trigger laws that criminalize seeking and providing an abortion. These laws prompted several period-tracking app companies to encrypt their users’ data to make it more difficult for the government to access period- and pregnancy-related information for criminal investigations. This Comment explores whether the Fourth Amendment and U.S. privacy statutes protect users of period-tracking apps from government surveillance. More specifically, this Comment argues that …

The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

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 …

On Warrants & Waiting: Electronic Warrants & The Fourth Amendment, Tracy Hresko Pearl

Indiana Law Journal

Police use of electronic warrant (“e-warrant”) technology has increased significantly in recent years. E-warrant technology allows law enforcement to submit, and magistrate judges to review and approve, warrant applications on computers, smartphones, and tablets, often without any direct communication. Police officers report that they favor e-warrants over their traditional, paper counterparts because they save officers a significant amount of time in applying for warrants by eliminating the need to appear in-person before a magistrate. Legal scholars have almost uniformly praised e-warrant technology as well, arguing that use of these systems will increase the number of warrants issued throughout the United …

Evolving Privacy Protections For Emerging Machine Learning Data Under Carpenter V. United States, Emily Nicolella

FIU Law Review

The Fourth Amendment’s third-party doctrine eliminates an individual’s reasonable expectation of privacy in information they willingly turn over to third parties. Government scrutiny of this information is not considered a search under the Fourth Amendment and is therefore not given constitutional protections. In the 2018 case Carpenter v. United States, the Supreme Court created an exception to the third-party doctrine. In Carpenter, a case involving the warrantless use of cell site location information (CSLI) in a criminal investigation, the Court held that individuals do have a reasonable expectation of privacy regarding CSLI. According to Chief Justice Roberts, despite the necessary …

Beware What You Google: Fourth Amendment Constitutionality Of Keyword Warrants, Chelsa Camille Edano

Washington Law Review

Many Americans have potentially had their privacy rights invaded through invisible, widespread police searches. In recent years, local and federal governments have compelled Google and other search engine companies to produce the personal information of users who have conducted a search query related to a crime. By using keyword warrants, the government can conduct a dragnet search for suspects, imposing suspicion on users and exposing their personal information. The keyword warrant is a symptom of the erosion of the Fourth Amendment protection against suspicionless searches. Not only is scholarship scarce on keyword warrants, but also instances of these warrants are …

Wiretapping The Internet: Analyzing The Application Of The Federal Wiretap Act’S Party Exception Online, Hayden Driscoll

Washington and Lee Journal of Civil Rights and Social Justice

The federal Wiretap Act—originally enacted to curtail the government’s unbridled use of wiretaps to monitor telephonic communications—was amended in 1986 to provide a private right of action, extending the Act’s Fourth Amendment-like protections to private intrusions. Since the advent of the internet, plaintiffs have attempted to predicate claims of unauthorized online privacy intrusions on the Wiretap Act. In response, defendants claim they are parties to the communications at issue and should be absolved of liability under the Act’s party exception. The federal circuit courts of appeal disagree on how the party exception applies in the internet context. This Note evaluates …

The Computer Got It Wrong: Facial Recognition Technology And Establishing Probable Cause To Arrest, T.J. Benedict

Washington and Lee Law Review

Facial recognition technology (FRT) is a popular tool among police, who use it to identify suspects using photographs or still-images from videos. The technology is far from perfect. Recent studies highlight that many FRT systems are less effective at identifying people of color, women, older people, and children. These race, gender, and age biases arise because FRT is often “trained” using non-diverse faces. As a result, police have wrongfully arrested Black men based on mistaken FRT identifications. This Note explores the intersection of facial recognition technology and probable cause to arrest.

Courts rarely, if ever, examine FRT’s role in establishing …

New Technology And The Right To Privacy: Do E-Scooters Implicate The Fourth Amendment?, Alexander P. Carroll

Journal of the National Association of Administrative Law Judiciary

The Fourth Amendment protects individual’s right to privacy from unwarranted searches and seizures, but the analysis for when the Fourth Amendment applies has become more complicated as new technology is developed. E-scooters are a new piece of technology which may implicate the Fourth Amendment. Cities across the country are beginning to require the mobility companies which provide e-scooter services to turn over location data in order to receive an operating permit. This article first provides a background of the Fourth Amendment, then provides details regarding the new city regulations. The article includes a discussion of the privacy concerns as well …

No Longer Innocent Until Proven Guilty: How Ohio Violates The Fourth Amendment Through Familial Dna Searches Of Felony Arrestees, Jordan Mason

Cleveland State Law Review

In 2013, the United States Supreme Court legalized DNA collection of all felony arrestees upon arrest through its decision in Maryland v. King. Since then, the State of Ohio has broadened the use of arrestee DNA by subjecting it to familial DNA searches. Ohio’s practice of conducting familial DNA searches of arrestee DNA violates the Fourth Amendment because arrestees have a reasonable expectation of privacy in the information that is extracted from a familial DNA search and it fails both the totality of the circumstances and the special needs tests. Further, these tests go against the intention of the …

Preservation Requests And The Fourth Amendment, Armin Tadayon

Seattle University Law Review

Every day, Facebook, Twitter, Google, Amazon, ridesharing companies, and numerous other service providers copy users’ account information upon receiving a preservation request from the government. These requests are authorized under a relatively obscure subsection of the Stored Communications Act (SCA). The SCA is the federal statute that governs the disclosure of communications stored by third party service providers. Section 2703(f) of this statute authorizes the use of “f” or “preservation” letters, which enable the government to request that a service provider “take all necessary steps to preserve records and other evidence in its possession” while investigators seek valid legal process. …

Protecting Online Privacy In The Digital Age: Carpenter V. United States And The Fourth Amendment’S Third-Party Doctrine, Cristina Del Rosso, Carol M. Bast

Catholic University Journal of Law and Technology

The goal of this paper is to examine the future of the third-party doctrine with the proliferation of technology and the online data we are surrounded with daily, specifically after the Supreme Court’s decision in Carpenter v. United States. It is imperative that individuals do not forfeit their Constitutional guarantees for the benefit of living in a technologically advanced society. This requires an understanding of the modern-day functional equivalents of “papers” and “effects.”

Looking to the future, this paper contemplates solutions on how to move forward in this technology era by scrutinizing the relevancy of the third-party doctrine due …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones

Cleveland State Law Review

Courts are divided as to whether law enforcement can collect cell phone location information in real-time without a warrant under the Fourth Amendment. This Article argues that Carpenter v. United States requires a warrant under the Fourth Amendment prior to law enforcement’s collection of real-time cell phone location information. Courts that have required a warrant prior to the government’s collection of real-time cell phone location information have considered the length of surveillance. This should not be a factor. The growing prevalence and usage of cell phones and cell phone technology, the original intent of the Fourth Amendment, and United States …

Warrantless Searches Of Electronic Devices At U.S. Borders: Securing The Nation Or Violating Digital Liberty?, Ahad Khilji

Catholic University Journal of Law and Technology

The steady increase of U.S. citizens traveling with smart phones and other electronic devices has been met with the rise of searches and seizures by CBP officers at U.S borders. Although only less than 0.1% of all travelers may actually be subjected to a search while entering the United States, when comparing the statistics between a six month period in 2016 with the same period in 2017, electronic device searches have almost doubled from 8,383 to 14,993. Approximately one million travelers to the U.S. are inspected by the CBP every day. Out of this population, nearly 2,500 electronic devices are …

Chilling: The Constitutional Implications Of Body-Worn Cameras And Facial Recognition Technology At Public Protests, Julian R. Murphy

Washington and Lee Law Review Online

In recent years body-worn cameras have been championed by community groups, scholars, and the courts as a potential check on police misconduct. Such has been the enthusiasm for body-worn cameras that, in a relatively short time, they have been rolled out to police departments across the country. Perhaps because of the optimism surrounding these devices there has been little consideration of the Fourth Amendment issues they pose, especially when they are coupled with facial recognition technology (FRT). There is one particular context in which police use of FRT equipped body-worn cameras is especially concerning: public protests. This Comment constitutes the …

The Outer Limits: Imsi-Catchers, Technology, And The Future Of The Fourth Amendment, Ryan C. Chapman

Pepperdine Law Review

Recent advances in technology are posing new challenges for a legal system based on decades-old precedent. Nowhere is this more apparent than in law enforcement’s warrantless use of IMSI Catchers. These devices mimic a cell phone tower, and when the device is activated, cell phones will naturally connect to them. Law enforcement officers can use those intercepted cell phone signals to track a suspect’s movements in real time with startling accuracy. Scholarly commentary on these devices has largely concluded that their use requires a warrant. This Comment engages in a close examination of Fourth Amendment precedent and argues that, as …

Civil Liberty Or National Security: The Battle Over Iphone Encryption, Karen Lowell

Georgia State University Law Review

On June 5, 2013, Edward Snowden released what would be the first of many documents exposing the vast breadth of electronic surveillance the Federal Bureau of Investigation (FBI) and the National Security Agency (NSA) had been conducting on millions of United States citizens. Although the federal agencies had legal authority under the Foreign Intelligence Surveillance Act (FISA) to collect metadata from companies such as Verizon, many Americans considered this data collection to be a massive invasion of privacy.

Equipped with the knowledge of sweeping domestic surveillance programs, citizens and technology firms fighting for strong privacy and security protection, have started …

Game Of Phones: The Fourth Amendment Implications Of Real-Time Cell Phone Tracking, Cal Cumpstone

Cleveland State Law Review

With the help of technological advancements, law enforcement can now hijack a targeted individual’s cell phone to ping and track the phone’s exact location in real time. Based upon previous rulings, this new tracking process has apparently fallen into a "grey area" of Fourth Amendment jurisprudence. However, real-time cell phone tracking should be a search in terms of the Fourth Amendment and, therefore, require a warrant. Real-time cell phone tracking infringes on an individual’s reasonable expectation of privacy, violates the trespass doctrine as a trespass to chattels, and violates the Kyllo standard by using technology not in general public use …

That ‘70s Show: Why The 11th Circuit Was Wrong To Rely On Cases From The 1970s To Decide A Cell-Phone Tracking Case, David Oscar Markus, Nathan Freed Wessler

University of Miami Law Review

In light of society's increasing reliance on technology, this article explores a critical question – that of the Fourth Amendment’s protection over privacy in the digital age. Specifically, this article addresses how the law currently fails to protect the privacy of one’s cell phone records and its ramifications. By highlighting the antiquated precedent leading up to the Eleventh Circuit’s ruling in United States v. Davis, this article calls on the judiciary to find a more appropriate balance for protecting the right to privacy in a modern society.

Cellphones, Stingrays, And Searches! An Inquiry Into The Legality Of Cellular Location Information, Jeremy H. D'Amico

University of Miami Law Review

Can the Fourth Amendment protect an individual’s right privacy by preventing the disclosure of her location through cell site location information? Does it currently? Should it? Many court opinions answer these questions in both the affirmative and the negative. The rationale underlying each conclusion is disparate. Some rely on statutory regimes, others rely on the United States Supreme Court’s interpretation of reasonableness. However, Cell Site Location Information is a technology that requires uniformity in its interpretation. This note investigates the different interpretations of the Fourth Amendment as it relates to Cell Site Location Information. It explains the technology behind Cell …

Small Data Surveillance V. Big Data Cybersurveillance, Margaret Hu

Pepperdine Law Review

This Article highlights some of the critical distinctions between small data surveillance and big data cybersurveillance as methods of intelligence gathering. Specifically, in the intelligence context, it appears that “collect-it-all” tools in a big data world can now potentially facilitate the construction, by the intelligence community, of other individuals' digital avatars. The digital avatar can be understood as a virtual representation of our digital selves and may serve as a potential proxy for an actual person. This construction may be enabled through processes such as the data fusion of biometric and biographic data, or the digital data fusion of the …

Dna Storage Banks: The Importance Of Preserving Dna Evidence To Allow For Transparency And The Preservation Of Justice, Cristina Martin

Chicago-Kent Law Review

What is the duty to preserve information in today’s society? In order for humanity to evolve, change and flourish in the future, society needs to preserve its information from the past. In the criminal justice field, preservation of evidence has special significance. DNA evidence in particular has become a helpful aid for innocent defendants who have been improperly imprisoned. Over the past twenty years, the number of exonerations of imprisoned criminal defendants has increased dramatically. With the advancement of technology, old, previously untestable or improperly tested DNA evidence will need to be retested. However, most states do not have proper …

How Privacy Killed Katz: A Tale Of Cognitive Freedom And The Property Of Personhood As Fourth Amendment Norm, Christian M. Halliburton

Akron Law Review

With each passing day, new technologies push the horizons of official government investigative and surveillance activity deeper and deeper into the mind and consciousness of the surveilled subject. While law enforcement agencies have always relied on observing the behavior and activity of suspicious targets, and there has been little judicial ink spent preserving the confidentiality of such observable activity, the law has been slow to respond to rapid increases in the capacity or scope of official observation that the advance of technologically sophisticated surveillance techniques helped facilitate. The sampling of techniques at the center of this Article allow the operators …

Coming To A Car Dealership Near You: Standardizing Event Data Recorder Technology Use In Automobiles, Kara Ryan

Chicago-Kent Law Review

Event Data Recorders are receiving more attention as owners of automobiles have begun to realize that their driving histories are recorded. Event Data Recorders are the “black boxes” in automobiles that are installed in the vast majority of vehicles currently on the road. In the majority of states, the restrictions on what information can be retrieved from Event Data Recorders and used by police officers, advertising firms, and insurance companies remains a gray area. State laws governing Event Data Recorder technology greatly fluctuates by jurisdiction. If Event Data Recorder information falls into the wrong hands, the possession of the data …
