The British Experience With Hearsay Reform: A Cautionary Tale, Mark S. Brodin

Mark S. Brodin

Among the proposals being considered by the Advisory Committee on the Federal Rules of Evidence (“the Committee”) is the scrapping of the categorical exception regime for hearsay, leaving questions of reliability and admissibility ad hoc to district court judges along the lines of Federal Rules of Evidence (FRE) 403 and 807. Over the past decades, the British have moved toward this approach, and it is the purpose of this Article to identify the lessons that can be learned from that experience, especially with regard to criminal prosecutions and the right of confrontation.

Small Cells, Big Problems: The Increasing Precision Of Cell Site Location Information And The Need For Fourth Amendment Protections, Robert M. Bloom, William T. Clark

Robert M. Bloom

The past fifty years has witnessed an evolution in technology advancement in police surveillance. Today, one of the essential tools of police surveillance is something most Americans carry with them in their pockets every day, the cell phone. Cell phones not only contain a huge repository of personal data, they also provide continuous surveillance of a person’s movement known as cell site location information (CSLI). In 1986, Congress sought to provide some privacy protections to CSLI in the Stored Communication Act. Although this solution may have struck the proper balance in an age when cell phones were a mere ...

Ask Versus Tell: Potential Confusion When Child Witnesses Are Questioned About Conversastions, Stacia N. Stolzenberg, Kelly Mcwilliams, Thomas D. Lyon

University of Southern California Legal Studies Working Paper Series

Children’s potential confusion between “ask” and “tell” can lead to misunderstandings when child witnesses are asked to report prior conversations. The verbs distinguish both between interrogating and informing and between requesting and commanding. Children’s understanding was examined using both field (i.e., Study 1) and laboratory (i.e., Studies 2-4) methods. Study 1 examined 100 5- to 12-year-olds’ trial testimony in child sexual abuse cases, and found that potentially ambiguous use of ask and tell was common, typically found in yes/no questions that elicited unelaborated answers, and virtually never clarified by attorneys or child witnesses. Studies 2-4 ...

Optimizing Collection Of Trace Biological Samples From Vehicle Headrests, Kevin Tang, Jesse Ramirez, John Bond, Jocelyn Weart, Yvette Delatorre, Ian Fitch, Steven Lee

Themis: Research Journal of Justice Studies and Forensic Science

Tape-lifting and swabbing are two methods commonly used for collecting biological samples in the United Kingdom and United States to investigate vehicle crimes. Determining the optimal collection method may lead to an increase in generating DNA profiles and crime-solving. The objective of this study is to evaluate the efficiency of adhesive tape and the double-swab collection methods for investigating vehicle crimes with possible touch DNA samples. Two experiments were conducted to evaluate the use of tape-lifts and swabs on spiked common vehicle fabric materials. The efficiency of recovery between the two collection methods was performed using qPCR. The results from ...

Physical Match: Unique Fracture Patterns In Wooden Popsicle Sticks, Yiu Ming Sunny Lau

Themis: Research Journal of Justice Studies and Forensic Science

Physical match (or physical fit) evidence was considered reliable in court for years, until the Daubert case, which required standardized scientific methodology on all forensic evidence. Physical matching faces the same criticism as other forms of physical evidence (specifically, that it lacks a scientific foundation). Physical matching is based on the idea that when an object is fractured, the shape of each fragment is unique and it is not possible to recreate a fragment that is identical to any other. In this study, fifty wooden popsicle sticks were broken in half, the pieces were mixed, and then reconstructed using physical ...

Minimum Education Requirements For Crime Scene Investigators, Araseli Saldivar

Themis: Research Journal of Justice Studies and Forensic Science

The initial crime scene investigation is critical since it is the primary step in the investigative process; therefore, individuals assigned to process a scene should be highly educated. Improperly educated (or uneducated) crime scene investigators (CSIs) can mishandle evidence during an investigation, affecting the outcome of cases. The minimum education requirement for CSIs should transition from a high school diploma—the current requirement—toward a bachelor’s degree. The importance of acquiring a college-level education is observed in a study conducted on crime scene examiners in Australia. To determine the educational requirement for CSIs in the United States, information was ...

Forensics’ Fight: A Need For Aggressive Strategies Against Confirmation Bias, Madison Mcgowan

Themis: Research Journal of Justice Studies and Forensic Science

In 2009, the National Academy of Sciences produced a lengthy report illuminating significant weaknesses present within the forensic community. One complex fault found in forensics was conformation bias. Since it is within human nature to make decisions based on contextual information, assumptions, and pre-held opinions, confirmation bias is an issue that will continue to persist. Therefore, stronger efforts must be made to recognize and abate the problem of bias within the field of forensics in order to preserve the notion that forensic science exists to serve principles of both truth and justice. Accordingly, this paper argues for the fight against ...

Why New Hampshire Must Update Rape Shield Laws, Amy Vorenberg

Legal Scholarship

[Excerpt] “Recent research indicates that New Hampshire has some of the highest rates of sexual assault in the nation; nearly one in four New Hampshire women and one in 20 New Hampshire men will experience sexual assault. Although reporting a crime can be hard for anyone, sexual assault victims have particular reasons for not reporting. After an assault, a rape victim typically feels embarrassment, shame and fears reprisal (most of these crimes are committed by an acquaintance). The deeply personal nature of rape makes it uniquely traumatizing and confusing.”

Challenging The Credibility Of Alleged Victims Of Child Sexual Abuse In Scottish Courts, Zsofia Szojka, Samantha J. Andrews, Michael E. Lamb, Stacia N. Stolzenberg, Thomas D. Lyon

University of Southern California Legal Studies Working Paper Series

This study examined the effects of credibility-challenging questions (n = 2,729) on 62 5- to 17-year-olds’ testimony in child sexual abuse cases in Scotland by categorizing the type, source, and content of the credibility-challenging questions defence lawyers asked and assessing how children responded. Credibility-challenging questions comprised 14.9% of all questions asked during cross-examination. Of defence lawyers’ credibility-challenging questions, 77.8% focused generally on children’s honesty, whereas the remainder referred to specific inconsistencies in the children’s testimony. Children resisted credibility challenges 54% of the time, significantly more often than they provided compliant responses (26.8%). The tendency to ...

Pragmatic Failure And Referential Ambiguity When Attorneys Ask Child Witnesses "Do You Know/Remember" Questions, Angela D. Evans, Stacia N. Stolzenberg, Thomas D. Lyon

University of Southern California Legal Studies Working Paper Series

“Do you know” and “Do you remember” (DYK/R) questions explicitly ask whether one knows or remembers some information while implicitly asking for that information. This study examined how 104 4- to 9-year-old children testifying in child sexual abuse cases responded to DYK/R wh- and yes/no questions. When asked DYK/R questions containing an implicit wh- question requesting information, children often provided unelaborated “Yes” responses. Attorneys’ follow-up questions suggested that children usually misunderstood the pragmatics of the questions. When DYK/R questions contained an implicit yes/no question, unelaborated “Yes” or “No” responses could be responding to the ...

"A Middle Temperature Between The Two": Exploring Intermediate Remedies For The Failure To Comply With Maryland's Eyewitness Identification Statute, Marc A. Desimone Jr.

University of Baltimore Law Review

This article addresses what remedies should be available to a criminal defendant in Maryland who has been identified in an extrajudicial identification procedure that does not comply with the present statutory requirements. Part II of this article provides an overview of the present due process test for evaluating the admissibility of extrajudicial eyewitness identifications, the present Maryland iteration of that test, and alternatives to that approach that have been adopted in other jurisdictions. Part III reviews recent legislative reforms to extrajudicial identification procedures, which are required in Maryland as of January 1, 2016. Section IV.A of this article argues ...

Error Costs, Legal Standards Of Proof And Statistical Significance, Michelle Burtis, Jonah B. Gelbach, Bruce H. Kobayashi

Faculty Scholarship

The relationship between legal standards of proof and thresholds of statistical significance is a well-known and studied phenomena in the academic literature. Moreover, the distinction between the two has been recognized in law. For example, in Matrix v. Siracusano, the Court unanimously rejected the petitioner’s argument that the issue of materiality in a securities class action can be defined by the presence or absence of a statistically significant effect. However, in other contexts, thresholds based on fixed significance levels imported from academic settings continue to be used as a legal standard of proof. Our positive analysis demonstrates how a ...

The Effects Of The Hypothetical Putative Confession And Negatively-Valenced Yes/No Questions On Maltreated And Non-Maltreated Children's Dislcosure Of A Minor Transgression, Stacia N. Stolzenberg, Kelly Mcwilliams, Thomas D. Lyon

University of Southern California Legal Studies Working Paper Series

This study examined the effects of the hypothetical putative confession (telling children “What if I said that [the suspect] told me everything that happened and he wants you to tell the truth?”) and negatively-valenced yes/no questions varying in their explicitness (“Did [toy] break?” vs. “Did something bad happen to the [toy]?”) on 206 4- to 9-year-old maltreated and non-maltreated children’s reports, half of whom had experienced toy breakage and had been admonished to keep the breakage a secret. The hypothetical putative confession increased the likelihood that children disclosed breakage without increasing false reports. The yes/no questions elicited ...

The Law Court's Proper Application Of Miranda In State V. Bragg: A "Matter-Of-Fact Communication" To The Defendant Regarding Evidence Against Him Will Not Typically Constitute "Interrogation", Stephen B. Segal

Maine Law Review

In State v. Bragg, Tammy Bragg was convicted of a Class D crime for operating under the influence (OUI) at the completion of a jury trial, and was ordered to pay a fine of $800 and her license was suspended for ninety days. During her trial, Bragg submitted a motion to suppress statements she made in the police officer’s vehicle and the police station on the grounds that she was not read her Miranda warnings prior to making the statements. The Superior Court denied her motion, however, concluding that Miranda warnings were not necessary in the officer’s vehicle ...
