Criminal justice in the Middle East

Criminal justice in the Middle East conjures up images of severed hands, religious police, and qadi justice. Yet those seeking a more accurate picture find few sources. Conventional treatments of the region focus on Islamic law, although few Middle Eastern states actually base their legal systems on Islamic law. This article argues that in the Middle East as elsewhere, rulers use criminal justice to achieve two related ends: to maintain order generally, and to maintain a particular order — to preserve the regime in power and the interests and values of those who support it. A comparative historical analysis of the emergence of the police and judiciary links these two ends, and these two institutions.     

An analysis of police officers' decisions about whether to refer cases of child abuse for prosecution

Facial composite research has mainly focused on their investigative value. No. comparable attention was drawn to their probative value – the extent to which a composite image may serve as incriminating or exonerating evidence against a defendant. The existing data resulting from mock-juror research allow only cautious conclusions and applies solely to the common law system. Therefore an experiment was conducted involving laypeople (N = 74) and prosecutor apprentices (N = 72). All participants received case materials of a robbery committed by a young male, including the victim's and defendant's testimonies and other evidence. In both samples, the facial composite evidence was manipulated so that participants viewed a composite image that was either a good or a poor match to the defendant. A facial composite that bore a strong resemblance to the defendant influenced the assessment of the eyewitness' credibility in the apprentices sample, but failed to affect other dependent variables. Surprisingly, laypeople ignored the facial composite no matter how well it resembled the defendant. Significant differences in the assessment of eyewitness' credibility, the strength of the defense case, the credibility of the defendant's alibi, and his culpability were found between the prosecutor apprentices and laypeople. The practical implications of these findings are discussed.     

Digital photographic evidence and the adjudication of domestic violence cases

This study reported the impact of digital photographic evidence on domestic violence case outcomes in two Indiana counties. It analyzed whether outcomes differed between cases with digital photographic evidence (treatment group) and cases with no photographic evidence (comparison group). Examined impacts included guilty pleas, convictions, and sentence severity. Data included in the analysis came from case files and police and prosecutor interviews. Findings suggest that digital photographic evidence can be a useful prosecutorial tool – treatment group members were more likely to plead guilty, be convicted, and receive more severe sentences.     

Screening Biological Stains with qPCR versus Lateral Flow Immunochromatographic Test Strips: A Quantitative Comparison using Analytical Figures of Merit

Biological fluid identification is an important facet of evidence examination in forensic laboratories worldwide. While identifying bodily fluids may provide insight into which downstream DNA methods to employ, these screening techniques consume a vital portion of the available evidence, are usually qualitative, and rely on visual interpretation. In contrast, qPCR yields information regarding the amount and proportion of amplifiable genetic material. In this study, dilution series of either semen or male saliva were prepared in either buffer or female blood. The samples were subjected to both lateral flow immunochromatographic test strips and qPCR analysis. Analytical figures of merit—including sensitivity, minimum distinguishable signal (MDS) and limit of detection (LOD)—were calculated and compared between methods. By applying the theory of the propagation of random errors, LODs were determined to be 0.05 μL of saliva for the RSID? Saliva cards, 0.03 μL of saliva for Quantifiler^® Duo, and 0.001 μL of semen for Quantifiler^® Duo. In conclusion, quantitative PCR was deemed a viable and effective screening method for subsequent DNA profiling due to its stability in different matrices, sensitivity, and low limits of detection.     

The association between investigative interviewers' knowledge of question type and adherence to best‐practice interviewing

It is well established that not all investigative interviewers adhere to ‘best‐practice’ interview guidelines (i.e., the use of open‐ended questions) when interviewing child witnesses about abuse. However, little research has examined the sub skills associated with open question usage. In this article, we examined the association between investigative interviewers' ability to identify various types of questions and adherence to open‐ended questions in a standardized mock interview. Study 1 , incorporating 27 trainee police interviewers, revealed positive associations between open‐ended question usage and two tasks; a recognition task where trainees used a structured protocol to guide their response and a recall task where they generated examples of open‐ended questions from memory. In Study 2 , incorporating a more heterogeneous sample of 40 professionals and a different training format and range of tests, positive relationships between interviewers' identification of questions and adherence to best‐practice interviewing was consistently revealed. A measure of interviewer knowledge about what constitutes best‐practice investigative (as opposed to knowledge of question types) showed no association with interviewer performance. The implications of these findings for interviewer training programs are discussed.
