The basis of citizen's perceptions of the criminal jury

Two studies examined citizens' perceptions of the criminal jury and their evaluations of 6- or 12-person juries operating under unanimous or majority decision rules. Study 1 was a telephone survey of 130 adult citizens in which respondents evaluated alternative jury structures in the abstract. In Study 2, students were asked to evaluate jury structures for a hypothetical trial in which they were either the defendant or the victim in a crime with a mild or serious outcome. In both studies, jury size and decision rule were related to ratings of procedural cost, and the severity of the crime moderated procedural evaluations. In Study 1, juries were preferred to judges and the 12-person unanimous jury was preferred over other jury structures when the crime involved was serious. In Study 2, there were no direct effects due to variations in jury structure, but subjects appeared to trade off procedural cost and thoroughness of deliberation as a function of the seriousness of the crime. Procedural fairness emerged as the strongest independent predictor of desirability for jury procedures, and fairness was related to representativeness and accuracy. The role manipulation did not influence subjects' responses. In both studies, respondents were very supportive of the jury as an institution, despite a perception that erroneous jury verdicts do occur.     

Working with street children

In September 1990 we became involved with the Centre for the Defence of the Child (CDM) in Brazil, hoping to participate in a survey of the lives of street children that was being conducted by the group. The CDM, a branch of its parent organisation The Young Street Vendors' Association, takes on individual cases of street children, providing crisis management with social, psychological, and legal support. It was decided to start a project of regularly taking a team of staff on to the streets and into the areas where the street children were, with the aim of providing a programme of support and self-esteem building, principally for the street girls. This project proved a success with the street children and remains so following our departure from Brazil.     

Assessing the effectiveness and efficiency of a police service: the analytics of operational reviews

Concerns over rising costs have forced police services to balance increasing fiscal and operational pressures. Discussions of the resources and requirements of police, however, are generally only informed by political expediency and traditional practice. Operational reviews (ORs) can be used to document the demands on police, their capacity to respond, and ways in which they can become more efficient and effective. Drawing on an OR of a major urban Canadian police service, this article provides a broad outline of the components of an OR and the analytics that can be used to answer these key questions.     

Forensic Evidence in Homicide Investigations and Prosecutions

Even though forensic evidence is collected at virtually every homicide scene, only a few studies have examined its role in investigation and prosecution. This article adds to the literature by providing the results of a study of 294 homicide cases (315 victims) occurring in Cleveland, Ohio, between 2008 and 2011. Through a logistic regression on open versus closed cases, the collection of knives, administration of gunshot residue (GSR) kits, and clothing at the scene were positively and significantly related to case closures, while collection of ballistics evidence and DNA evidence were statistically significant in the opposite direction. With regard to analysis, the clearance rate for cases with probative results (i.e., matches or exclusions) was 63.1% compared to a closure rate of 56.3% for cases without probative results. However, only 23 cases had probative results prior to arrest compared to 128 cases with probative results after arrest.
