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 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 …

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 …

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 …

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

David Kaye

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

David Kaye

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 …

Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

David Kaye

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic area …

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

David Kaye

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 …

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 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 …

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 …

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 …
