Racial and ethnic disparity in pretrial criminal processing

This study uses data on the processing of felony defendants in large urban courts to analyze racial and ethnic disparities in pretrial processing. There are three major findings. First, racial disparity is most notable during the decision to deny bail and for defendants charged with violent crimes. Second, ethnic disparity is most notable during the decision to grant a non‐financial release and for defendants charged with drug crimes. Third, when there is disparity in the treatment of Black and Latino defendants with similar legal characteristics, Latinos always receive the less beneficial decisions. These findings are consistent with the theoretical perspective offered, which suggests that stereotypes influence criminal processing when their specific content is made salient by either the concerns relevant to a particular processing decision or the crime type of a defendant’s primary charge.     

A survival model of pretrial failure

This paper examines the likelihood of rearrest during the pretrial period with a model that depends on both time elapsed since release and on individual and case characteristics. Using data on a sample of male arrestees released on recognizance in the District of Columbia in 1984, we apply a survival or hazard model to the problem of predicting pretrial rearrest. We are particularly interested in whether drug use, as measured by urinalysis at arrest, is predictive of pretrial rearrest and its timing. Results show, for example, that drug use or a charge for larceny is associated with high risk levels in the period immediately following release. In our data, the number of prior convictions exerts a strong effect on rearrest risk throughout the pretrial period, but the initial high risk associated with being on probation or parole or having pending charges decreases rapidly over the course of a year at risk.     

Predicting pretrial misconduct with drug tests of arrestees: Evidence from eight settings

Identifying defendants at high risk of pretrial misconduct is a major problem for the judiciary. Currently, some have argued that testing arrestees for recent drug use is one way to distinguish between those who will and those who will not commit pretrial misconduct. The research reported here questions whether the incremental predictive power resulting from drug testing always improves predictions of pretrial misconduct. Using survival analysis to study time until rearrest and a probit model to analyze the occurrence of a failure to appear, we show that urine test results have no consistent power to predict pretrial misconduct after accounting for defendant's criminal records, community ties, and other factors commonly known by the court. These results are based on our analysis of eight data sets from different locales, time periods, and age groups.     

Criminal justice decision making as a stratification process: The role of race and stratification resources in pretrial release

Our purpose is to bridge the criminal justice and stratification research literatures and to pursue the argument that homologous structural principles stratify allocation processes across central institutions of American society. The principle observed here in the making of bail decisions, as in earlier studies of the allocation of earnings, is that stratification resources operate to the greater advantage of whites than blacks. The operation of this principle is established through the estimation of covariance structure models of pretrial release decisions affecting 5660 defendants in 10 federal courts. Education and income are treated in this study as observed components of a composite construct, stratification resources, which works to the greater advantage of whites. Prior record is also found to operate to the greater advantage of whites. Two further variables, dangerousness and community ties, increase bail severity among blacks and whites. While the effect of community ties has been legally legitimized since the Bail Reform Act of 1966, the effect of dangerousness was not so legitimized until the Bail Reform Act of 1984. However, because our data precede the latter act, they confirm that this act simply reinstitutionalized earlier practice. Meanwhile, our race-specific findings may explain why although this and earlier studies find negligible main effects of race on criminal justice outcomes, black Americans nonetheless perceive more criminal injustice than do whites. In the criminal justice system, as in other spheres of American society, whites receive a better return on their resources, but our findings that the statutory severity of the offense and dangerousness work to the relative disadvantage of white defendants challenges conflict and labeling theory's one-dimensional characterization of black defendant disadvantage.     

Rape law reform and the effect of victim characteristics on case processing

Rape law reforms enacted during the past 20 years were designed to shift the focus of a rape case from the victim to the offender. Reformers and criminal justice officials speculated that changes in the rules of evidence and enactment of rape shield laws would result in less suspicion of the claims of rape victims and would make it less likely that the character, reputation, and behavior of the victim would affect decision making about the case. In this paper we examine the impact of rape law reform on the factors affecting the outcome of sexual assault cases bound over for trial in Detroit. We find little support for our hypothesis that the effect of victim characteristics on case processing decisions declined in the postreform period. Most of the victim characteristics did not have the expected effects on the likelihood of case dismissal, charge reduction, conviction, or incarceration. We did, on the other hand, find that the proportion of cases involving evidence of risk-taking behavior on the part of the victim or questions about the victim's credibility increased in the postreform period.     

Prosecutorial discretion in seeking death: An analysis of racial disparity in the pretrial stages of case processing in a midwestern county

In the 1987 case of McCleskey v. Kemp, the U.S. Supreme Court appeared to foreclose the possibility of challenging racial bias in capital sentencing by using statistically based claims of discrimination. McCleskey, however, does not prevent a challenge to decisions made by particular individuals during the capital punishment process. In this study we examined pretrial decisions made by, or under the direction of, one prosecutor to determine whether those decisions had been influenced by race. We found that homicide cases involving black defendants and white victims fared worse than other racial combinations in all of the pretrial decisions made: They were more likely to result in first-degree murder charges, to be served notice of aggravating circumstances, and to proceed to capital trial.     

Questioning mandatory sentencing efficiency: A case study of persistent felony offender rapists in Kentucky

This policy analysis explores the incapacitative efficiency of Kentucky’s career criminal statute in averting the recidivism of offenders convicted of rape. The study utilizes a 1985 cohort of Kentucky persistent felony offenders with at least one rape conviction (n = 62) and tracks recidivism rates up to fifteen years later. The results question the efficiency of mandatory sentencing. In general, mandatory minimum sentences (where offenders are not eligible for statutory good time or parole) kept these offenders incarcerated beyond the time necessary to avert future crimes.

Implementation of a semi-automated processing system for DNA profiling of forensic casework samples

The concept for a semi-automated processing system for DNA analysis of crime scene samples was developed at the Landeskriminalamt Baden-Württemberg (LKA BW) and comprises the extraction of genomic DNA from human cells by ChargeSwitch^® magnetic bead technology (CST), quantification of purified DNA by real-time PCR, amplification of short tandem repeats (STRs) by PCR and DNA fragment length analysis of STRs by capillary electrophoresis. Three liquid handling workstations from Tecan, a real-time PCR device and a 16-channel capillary electrophoresis (CE) system, both from Applied Biosystems (AB), are linked via laboratory data network. Transmission and management of sample and analysis data is enabled by a Laboratory Information and Management System (LIMS). Suitability for a wide range of stain types, early exclusion of DNA-free samples, barcode sample identification and prevention of cross-contaminations guarantee efficiency and high quality standards.     

Prevalence and Processing of Child Sexual Abuse: A Multi-Data-Set Analysis of Urban and Rural Counties

This study investigated how contextual factors affect the processing of child sexual abuse cases, from reporting to sentencing. We analyzed three types of data: (a) data compiled by the Pennsylvania Coalition Against Rape from monthly reports by all rape crisis centers in the state; (b) data from the Pennsylvania Office of Children, Youth, and Families; and (c) sentencing data from the Pennsylvania Commission on Sentencing. Results indicated that aggregate rates of reporting, substantiation, and sentencing were affected by county levels of expenditure. In addition, reporting and substantiation were affected by county-level factors, such that rural counties, counties with a higher percentage of individuals living below the poverty level, counties with higher expenditures, and counties with a higher percentage of stranger assaults had higher rates of child sexual abuse reporting.

The relationship between bedding and face-down death in infancy: mathematical analysis of a respiratory simulation system using an infant mannequin to assess gas diffusibility in bedding

Rebreathing is a model for the relationship between a prone sleeping position and sudden infant death syndrome. This study used a mechanical simulation model to establish the relationship between types of bedding and rebreathing potential for an infant placed prone (face down) at different postnatal ages. The infant mannequin was connected to a respirator set to deliver physiologically appropriate combinations of tidal volume (V(T)) and respiratory rates (RR) across a range of postnatal ages (0-18 months). Before measurements were made, CO(2) flow was regulated to 5+/-0.1% of end-tidal PCO(2) (EtCO(2)). After the model was placed in a prone position, any increase in the fractional concentration of inspired CO(2) (FiCO(2)) was measured. FiCO(2) increased immediately and rapidly, and reached a maximum value within a few minutes. The maximum FiCO(2) ranged from under 2% to over 10%, depending on the bedding. FiCO(2) was also affected by V(T) and RR. This model is not applicable to actual infants because of the large tissue stores of CO(2) in infants; however, it is useful for evaluation of gas diffusibility of bedding and will simplify the investigation of sleeping environments when a baby is found dead with its face covered by soft bedding. In general, the higher the FiCO(2), the greater the rebreathing potential. Theoretically, considering the paucity of body stores of O(2), changes in FiO(2) would be affected not by changes in FiCO(2), but by CO(2) production and gas movement around the infant's face. The rapid decrease of FiO(2) is approximated at the inverse of the FiCO(2) timecourse, suggesting the significance of not only CO(2) accumulation but also O(2) deprivation in the potential space around the baby's face.     

A model of institutional network dynamics and a comparative case analysis of information technology transfer

This paper examines the institutional network dynamics of information technology transfer with particular emphasis on the roles of publicly-funded centers for research and development at the national and regional policy-making levels. The conceptual model serves as a basis for qualitative case analysis and comparison of research management structures in two Canadian research centers located in Quebec Province. Conclusions are formulated regarding the complementarity of program and project dominant structures as well as the comparison of hierarchies and markets as technology transfer control mechanisms. Program dominant management appears appropriate to development of national innovation infrastructures, while project dominant management facilitates problem solving in regional innovation networks. The consequences of these conclusions for research management in global technological markets are discussed. This research was funded by a grant from the Social Sciences and Humanities Research Council of Canada. The names of the research centers under study have been changed.     

Revisiting the choice model of Ponzi and Pyramid schemes: analysis of case law

This exploratory study operationalizes the variables comprising the choice model of white collar crime through analyzing cases decided by federal courts, the Securities and Exchange Commission (SEC), and the Federal Trade Commission (FTC). Cases were extracted from the LEXIS-NEXIS, WESTLAW, and the NERA Economic Consulting databases and categorized according to the indicators of the choice model: size of pool of criminally predisposed, supply of lure, prevailing beliefs about credibility of external oversight, internal oversight and self-restraint, and supply of criminal opportunities. The findings show that unequal access to information among the investors and misuse of trust and affinity relationships affected the size of the pool of criminally tempted individuals. Supply of lure was affected through advances in modern technology and promises of wealth and material success at low costs and risks. Prevailing beliefs about the credibility of external oversight and internal corporate regulatory controls were affected by the efficiency and effectiveness of enforcement authorities. Variables described by the choice model of white collar crime can be operationalized through analysis of existing case law.     

Individualization,criminalization, or problem resolution: A factorial survey of juvenile court judges' decisions to incarcerate youthful felony offenders

Existing research on the criteria used by juvenile court judges in choosing dispositions is limited in two respects. First, the predictor variables included in most investigations have been limited either in number or in the quality of their measurement. Second, research has not focused on sentencing decisions for serious offenders. Using a factorial survey of juvenile court judges, the present study seeks to determine what factors shape disposition decisions for juvenile felony offenders. The results suggest that judges focus primarily on offense characteristics, and are influenced only marginally by the offender's social characteristics. These findings are more consistent with the view that juvenile courts are becoming “criminalized” than with the view that individualized treatment is the goal. An alternative interpretation—that judges may be problem solvers, trying to dispose of cases efficiently—also is proposed.     

The implementation of case formulation by probation officers: service user and carer views

Background: The recent UK Government strategy on high-risk offenders with personality disorders (PD) proposes improved identification of this group, assessment of their treatment needs through case formulation (CF) and the subsequent provision of treatment pathways. Little is known about service user and carer views on this strategy. Aims/Hypotheses: This study sought to identify the views of personality-disordered (PD) offenders and carers on the proposed role of Probation staff in CF. Methods: Three focus groups were carried out, two with service users and one with carers, with a total of 10 participants overall. Results: Five themes emerged: ‘power’, ‘conflicting roles’, ‘trust’, ‘building a relationship through consistency of care’ and ‘hope and possibility’. Conclusions/Practical implications: Offenders and carers were sceptical regarding the proposed role of Offender Manager (OMs) in CF and this could pose a potential barrier to the successful implementation of the strategy.     

影响性刑事冤假错案的产生、纠错、追责与民意的关联考察——以22起影响性刑事冤假错案为主要研究范本

民意的影响是冤假错案产生的诱因之一。不理性的民意极易虚构出貌似合理的"案件事实"并以此给司法机关施压。基于民意的压力,司法机关往往更多注重有罪证据,忽视无罪证据。命案必破、限期破案、疑罪从轻等刑事政策、司法理念,都是对民意诉求的顺应,也是促成冤假错案的诱因。民意对影响性冤假错案的纠错有积极意义,但仍应回归法治轨道。样本案件中,民意推进了冤假错案纠错程序的启动、纠错的及时,但没有制度化。民众对司法活动的认知不够理性,对错案追责的民意表达亦非建立在理性认知的基础之上。我国有必要培育理性的民意,形成民意与刑事司法的良性互动。     

An unusual case of sudden unexpected death: postmortem investigation and biomechanical analysis of the cervical spine

A naked man died under peculiar circumstances and the postmortem examination revealed unexpected lesions in the cervical spine. Investigations of the cervical spine (computed tomography, magnetic resonance imaging, and histological examination) showed that a piece of bone was torn of the anterior part of vertebra C6 and that there was fresh bleeding in the surrounding tissue. The cause of death remained unclear but was most likely cardiac arrhythmia initiated by beta-2 agonist inhalation due to an acute asthmatic attack. Data from biomechanical investigation using finite element analysis supported the conclusion that the cervical spine injury was secondary to impact during falling as a consequence of the cardiac arrhythmia.     

International mutual legal assistance in criminal law made redundant: A comment on the Belgian Yahoo! case

This article offers a critical examination of the court judgements in a recent Belgian case against Yahoo!. It examines the challenges related to the establishment of jurisdiction for Internet-based services and the role that procedures of mutual legal assistance should play. Belgian law obliges providers of “electronic communications services/electronic communications networks” to cooperate with Belgian law-enforcement authorities and to handle over communication and personal data. Although the terms are derived from the EU Electronic Communications Regulatory Framework, a much broader interpretation to them was finally given by the Belgian Supreme Court. Seemingly this implies that, from now on, a US-based company such as Yahoo! is, at least under Belgian law, under a legal obligation to directly comply with an order issued by Belgian law-enforcement authorities.
