Prospective and Retrospective Exposure Assessment

Though prospective regulatory exposure assessment and retrospective forensic exposure reconstruction rely on the same tools, they have a very different focus, require a distinct approach, and depend on different types of data. Inappropriate application of prospective regulatory exposure assessment methods to forensic exposure reconstruction can result in exposure estimates that differ significantly from actual historical exposures. This article compares prospective exposure assessment and forensic exposure reconstruction, with the goal of describing their distinctive focuses (e.g., population-based versus individual-based) and data needs.     

Analysis of Gunshot Residue and Associated Materials—A Review

Abstract: A comprehensive review of the scientific literature on gunshot residue (GSR) is presented. Aspects of both inorganic and organic GSR are discussed, from formation and distribution, to sample collection, preparation, and analysis using a variety of techniques. The interpretation of GSR results is also considered including issues surrounding the contamination, distribution, and transfer of GSR. Potential problems with ulterior sources of GSR like particles have been reported in the literature. For example, particles from environmental and occupational sources have been highlighted as exhibiting similar chemical and morphological characteristics to GSR. These findings are put into context with regard to interpreting samples. A move toward a “case by case” approach is argued to be more preferable to a “formal” classification system where possible. The analysis of both inorganic and organic compositions of residue samples as well as morphological considerations is considered to be a more ideal approach to GSR analysis, whereever practicable.     

Using Carbon,Oxygen, Strontium,and Lead Isotopes in Modern Human Teeth for Forensic Investigations: A Critical Overview Based on Data from Bulgaria

Isotopic data obtained from human remains can provide information about an individual's origin, migration, and diet. We evaluate the usefulness of carbon, oxygen, strontium, and lead isotopes for forensic investigations by comparing data from Bulgarian teeth with data from other regions. Geo‐referencing based on oxygen or strontium isotopes can be misleading due to overlap with other countries in Europe and other continents. Carbon and lead isotopes, in combination with oxygen and strontium isotopes, provide the most useful information for identification of local vs foreigner status. In particular, high‐precision Pb isotopes show a distinct “Bulgarian” range; however, it is possible that individuals from other countries in Eastern Europe and/or central to western Asia could have overlapping isotopic values. Additional high‐precision multi‐isotope data from modern humans from different regions in the world are required to transition from speculative to more quantitative estimation of a geographical place of origin for unidentified human remains.     

Police services detention centres: a proposed solution for action

Police services face daily challenges dealing with the health issues displayed by individuals in their custody. They often find themselves isolated from the services that can help the most. This paper scopes relevant literature on these challenges and some of the interprofessional interventions which have emerged to address them, such as the diversionary practices of crisis intervention teams, street triage, nurses in custody suites, and court liaison and diversion. Remote presence technology is proposed to be an innovative solution that can help to provide more efficient and effective pathways for care in Police Detention Centres. Remote presence technology has the ability to significantly affect the way interprofessional collaboration can take place for those in police custody.     

Fate and Behavior of Gunshot Residue: Recreational Shooter Vehicle Distribution

The susceptibility for recreational shooters to transfer gunshot residue (GSR) to both the interior and exterior of a vehicle is investigated. A comprehensive sampling protocol was used to assess the most likely areas of GSR transfer from recreational shooter contact, such as the steering wheel and the area, the firearms were stored (the trunk). Up to 315 characteristic GSR, particles were found in several locations throughout the interior of a vehicle. As many as 876 characteristic particles were found throughout a single vehicle. The data indicate that vehicles frequently occupied by firearms users are a potential source for inadvertent transfer of GSR to persons unrelated to firearm activity. In criminal cases where vehicles have been used, such transfer processes for GSR need to be considered within the context of any case interpretation. The implications for subsequent contamination and transfer processes from such vehicles require further investigation.     

Introducing 3D Printed Models as Demonstrative Evidence at Criminal Trials

This case report presents one of the first reported uses of a 3D printed exhibit in an English homicide trial, in which two defendants were accused of beating their victim to death. The investigation of this crime included a micro‐CT scan of the victim's skull, which assisted the pathologist to determine the circumstances of the assault, in particular regarding the number of assault weapons and perpetrators. The scan showed two distinct injury shapes, suggesting the use of either two weapons or a single weapon with geometrically distinct surfaces. It subsequently served as the basis for a 3D print, which was shown in court in one of the first examples that 3D printed physical models have been introduced as evidence in a criminal trial in the United Kingdom. This paper presents the decision‐making process of whether to use 3D printed evidence or not.     

Parental Indifference and Children’s Digital Piracy in South Korea: Mediation Effects of Low Self-Control and Misconception

Digital piracy is a global concern for society. Although adolescents’ digital piracy in South Korea is pervasive, its cause has rarely been examined. Using data collected by the Korean Institute of Criminology (KIC) in 2009, this study conducted structural equation modeling to determine if low self-control and social learning theory accounted for digital piracy. This study found that parental indifference increased adolescents’ digital piracy through low self-control and misconception about digital piracy. However, there were no direct effects of parental indifference on the digital piracy behaviors. In particular, the mediation effect in the model combining low self-control and misconception was greater compared to other models. Overall, the combination of low self-control and social learning theory provided a more meaningful framework to explain adolescents’ digital piracy. Results of this study can offer ways to aid in the examination and remediation of this particular form of deviant behaviors on the Internet by adolescents.     

Nobody gives a #%&!: a factorial survey examining the effect of criminological evidence on opposition to sex offender residence restrictions

Objectives

This short report tests whether altering messages concerning the presentation (i.e., criminal justice actor experience vs. summary of scientific findings) or nature of criminological research findings (i.e., lack of crime control effect vs. collateral consequences) regarding the (in)efficacy of sex offender residence restrictions (SORR) would subsequently affect public support for this policy.

Methods

The experimental conditions were presented in a factorial survey delivered to a national online panel, which was subsequently matched to a sampling frame representative of US adults on the basis of gender, age, race, education, ideology, and political interest (N?=?970). Analysis of variance was used to estimate the impact of the experimental manipulations on SORR opposition.

Results

Support for SORR was high across all experimental conditions, and no manipulations were statistically associated with variation in opposition to the policy.

Conclusions

The results support limited previous research suggesting that the public would continue to support SORR even in the lack of evidence to its effectiveness. This research suggests that altering the presenter or nature of research evidence subsequently produces no opinion change, at least in the form that was executed here. Further research on the mechanisms underlying the recalcitrance of SORR support is necessary.

     

Traumatic brain injury in a forensic intellectual disability population

Traumatic brain injury (TBI) screening in forensic populations has been recommended, due to a high prevalence, links to specific offence profiles and poorer outcomes, such as higher rates of psychiatric disturbance, longer stays in prison, and reoffending. Research focusing on TBI among offenders with intellectual disability (ID) is lacking. This study therefore describes the implementation of TBI screening using the Brain Injury Screening Index (BISI©), TBI prevalence and correlates in a forensic ID service. TBI appeared under recorded in case notes, with considerably more patients self-reporting TBI. Reported causes of TBI differed somewhat to the general population, including childhood physical abuse, self-harming behaviour, and assault. Approximately one-third of injuries did not receive any treatment. Though further adaptations may be required on current screening measures for TBI in offenders with ID, screening can provide valuable information, contributing positively to individual patient therapeutic and risk formulations.
