A Validation Study of Bullet and Cartridge Case Comparisons Using Samples Representative of Actual Casework

The foundation of firearm and tool mark identification is that no two tools should produce the same microscopic marks on two separate objects that they would be inaccurately or wrongly identified. Studies addressing the validity of identification infrequently employ tests that mirror realistic casework scenarios. This study attempted to do so using a double‐blind process, reducing test‐taking bias. Test kits including bullets and cartridge cases but not the associated firearms were completed by 31 analysts from 22 agencies. Analysis of the results demonstrated an overall error rate of 0.303%, sensitivity of 85.2%, and specificity of 86.8%. Variability in performance across examiners is addressed, and the effect of examiners’ years of experience on identification accuracy is explored. Finally, the article discusses the importance of studies using realistic case work scenarios when validating the field's performance and in providing courts with usable indicators of the accuracy of firearm and tool mark identification.     

Convict Criminology and the Struggle for Inclusion

Convict Criminology (CC) began in the early 1990s as a reaction to the then current state of academic criminology that did not adequately reflect the voices of convicted felons. Since its beginnings, CC has attempted to draw attention to a range of problems created by the criminal justice apparatus and defenders of the status quo. Dr. Joanne Belknap’s 2014 ASC presidential address and subsequent article presented an argument that stressed the importance of activism to be considered as part of criminological research. In the process, she reviewed her career and then criticized the field of Critical Criminology, in particular Convict Criminology. The article, however, ignored the numerous efforts that CC has engaged in to build an inclusive group school, movement, organization and network that includes the diverse voices of Ph.D. educated convicts and excons, and overall reflected a superficial understanding of the history and intent of Convict Criminology. This article attempts to explain the shortcomings of Belknap’s article and clarifies misunderstandings.     

African American Child Discipline: Differences Between Mothers and Fathers

Child rearing methods used in African American homes have been the subject of much commentary among social scientists, child welfare, and legal personnel. Much of the deliberation has centered on firm disciplinary techniques used by African American mothers. However, few studies have included the perspectives of African American fathers. This study investigated the differences between African American mothers' and fathers' responses in relation to child misbehavior. Several significant differences were found with mothers utilizing more intense disciplinary methods than African American fathers. Results of this investigation underscored the importance of obtaining the viewpoints of African American fathers as well as mothers in understanding parenting in African American homes.     

The rise and fall of Québecois separatist terrorism: A qualitative application of factors from two models

During the 1960s and early 1970s, there was a rise in oppositional political terrorism in Québec committed by individuals and organizations that wanted the province to separate from the rest of Canada. This situation provides an excellent case study that demonstrates the phenomenon that many of the same factors that lead to the rise of terrorism also cause its decline.     

Do pre‐admonition suggestions moderate the effect of unbiased lineup instructions?

We examined the additive and interactive effects of pre‐admonition suggestion and lineup instructions (biased or unbiased) on eyewitness identification rates. Participants watched a mock crime video, completed a target‐absent lineup identification, and completed a retrospective memory questionnaire. Prior to attempting an identification, participants were either exposed or not exposed to pre‐admonition suggestions and received biased or unbiased lineup instructions. The pre‐admonition suggestion indicated that it was likely that the perpetrator was in the lineup (surely, you can pick the perpetrator). The pre‐admonition suggestion increased false identification in the unbiased lineup condition. Furthermore, those who received the pre‐admonition suggestion were more certain in their identifications as well as other testimony‐relevant judgments than were those who did not receive the pre‐admonition suggestion. These results suggest that pre‐lineup suggestion can mitigate the beneficial effects of unbiased lineup instructions.
