Although certain pockets within the broad field of academic psychology have come to appreciate that eyewitness memory is more reliable than was once believed, the prevailing view, by far, is that eyewitness memory is unreliable—a blanket assessment that increasingly pervades the legal system. On the surface, this verdict seems unavoidable: Research convincingly shows that memory is malleable, and eyewitness misidentifications are known to have played a role in most of the DNA exonerations of the innocent. However, we argue here that, like DNA evidence and other kinds of scientifically validated forensic evidence, eyewitness memory is reliable if it is not contaminated and if proper testing procedures are used. This conclusion applies to eyewitness memory broadly conceived, whether the test involves recognition (from a police lineup) or recall (during a police interview). From this perspective, eyewitness memory has been wrongfully convicted of mistakes that are better construed as having been committed by other actors in the legal system, not by the eyewitnesses themselves. Eyewitnesses typically provide reliable evidence on an initial, uncontaminated memory test, and this is true even for most of the wrongful convictions that were later reversed by DNA evidence.

AbstractForensic evidence is an evolving science in the field of criminal investigation and prosecutions. It has been widely used in the administration of justice in the courts and the Western legal system, particularly in common law. To accommodate this new method of evidence in Islamic law, this article firstly, conceptualizes forensic evidence in Islamic law.  Secondly, explores legal frameworks for its adoption in Islamic law. Keywords: Forensic Evidence, legal framework, Criminal Investigation, Sharīʿah.AbstrakBukti forensik adalah sains yang sentiasa berkembang dalam bidang siasatan jenayah dan pendakwaan. Ia telah digunakan secara meluas dalam pentadbiran keadilan di mahkamah dan sistem undang-undang Barat, terutamanya dalam undang-undang common (common law). Untuk menampung kaedah pembuktian baru ini dalam undang-undang Islam, artikel ini, pertamanya, konseptualisasikan bukti forensik dalam undang-undang Islam. Kedua, ia menerokai rangka kerja undang-undang untuk penerimaannya dalam undang-undang Islam.Kata Kunci: Bukti Forensik, Rangka Kerja Guaman, Siasatan Jenayah, Sharīʿah.

Based on an ethnographic study of fingerprint and DNA evidence practices in the Swedish judicial system, this article analyses the materialization of forensic evidence. It argues that forensic evidence, while popularly understood as firmly rooted in materiality, is inseparably technoscientific and cultural. Its roots in the material world are entangled threads of matter, technoscience and culture that produce particular bodily constellations within and together with a particular sociocultural context. Forensic evidence, it argues further, is co-materialized with crimes as well as with particular bodily and social constellations. Consequently, the article suggests that an analysis of how forensic evidence is produced can contribute to feminist understandings of the inseparability of sex and gender: understanding bodies as ongoing technoscientific-material-cultural practices of materialization may be a fruitful approach to analysing their complexity, and the relationships in which they are placed, without surrendering to either cultural or biological determinism. Taking a theoretical point of departure not only in an STS-informed approach, but also in material feminist theorizations, the article also underlines that the suggested theoretical conversations across borders of feminist theory and STS should be understood as a two-way-communication where the two fields contribute mutually to each other.

Fingerprint identification has long been used by law enforcement to either identify or eliminate potential suspects in a case. It relies on friction ridges – the upraised skin that forms grooves on fingers – and friction ridge impressions, which form from natural secretions of sweat and other trace components. Latent prints, a common term for friction ridge impressions, have many benefits and advantages as a type of forensic evidence. However, they are not a perfect tool: wrongful convictions identified by post-conviction DNA testing and the re-evaluation of forensic evidence have spawned criticism and investigation into the scientific basis of this branch of forensics. This literature review examines literature in both the scientific and legal fields, and investigates three main themes: the principle of uniqueness assumed in individualization, the presence of cognitive bias and human error in analysis, and the changing role of expert testimony in court. There are arguments both for and against uniqueness, but it is still difficult to prove using statistical models and data analysis. Bias in examiners, on the other hand, undeniably exists in different ways, and should be actively guarded against in fingerprint analysis and expert testimony. Expert witness testimony that misleads, exaggerates, or is scientifically unsupportable has been linked to wrongful convictions in the past, highlighting the importance of careful regulation of how an expert witness is advised to testify. In addition to these topics, the techniques of collecting latent print evidence and the standard procedures of analysis have also been examined and evaluated for potential sources of error. Le maintien de l’ordre public utilise depuis longtemps les empreintes digitales pour identifier et éliminer des suspects d’une affaire criminelle. Les empreintes digitales se ent aux crêtes papillaires — les crêtes et les creux qui formes des rainures sur les doigts — et des empreintes des crêtes papillaires, ce qui se forme par les sécrétions naturelles de transpiration et autres composantes de traces. Les empreintes latentes, un terme courant pour les empreintes digitales, possèdent plusieurs avantages en tant qu’élément médico-légal de preuve. Toutefois, ce n’est pas une ressource able; des condamnations injustifiées identifiées par un test d’ADN post-condamnatoire et la réévaluation de l’évidence médico-légale ont frayé des critiques et des enquêtes de la base des sciences des empreintes digitales. Cette revue examine les textes dans les domaines scientifiques et médico-légaux, et examine trois thèmes : le principe d’unicité assumé par l’individualisation, la présence d’un biais cognitif et l’erreur humaine dans l’analyse, et le rôle changeant de témoignages experts devant la Cour. Il existe des arguments pour et contre l’unicité, mais l’unicité est tout de même difficile à prouver en utilisant les modèles statistiques et l’analyse de données. Un préjugé chez les examinateurs, d’autres parts, existe incontestablement, et devrait être activement évité lors de l’analyse d’empreinte digitale et de témoignages experts. Le témoignage d’expert qui induit en erreur, qui est exagéré ou qui est scientifiquement faux a mené à des condamnations injusti ées dans le passé, ce qui met en évidence l’importance d’une législation prudente sur comment l’expert est conseillé de témoigner. En plus de ces thèmes, les techniques de collecte des empreintes digitales latentes et les procédures normales d’analyse ont aussi été examinés et évalués pour des sources d’erreurs potentielles.

Prosecutors and members of law enforcement have complained that television shows such as CSI: Crime Scene Investigation have cultivated in jurors’ unreasonable expectations about forensic evidence, specifically that jurors require definitive forensic proof of guilt, or else they will wrongly acquit. This is popularly known as “CSI Effect.” Despite the popularity of this belief, there is little empirical evidence substantiating it. In fact, the majority of studies exploring CSI Effects have found evidence supporting a variety of impacts that advantage, rather than disadvantage, the prosecution. For instance, these programs frame forensics as objective and virtually infallible, bolster forensic technicians and the value of evidence associated with them, and promote schema that endorse prosecution narratives. Indeed, it appears that among CSI’s most salient impacts on the legal system comes not from these television programs distorting juror decision-making, but because lawyers and judges mistakenly believe such an effect exists, and, therefore, alter their behavior in response. It thus appears that the realities of the CSI Effect are quite different than the persistent mythology of it.

Biased expert witnesses pose a distinct challenge to the legal system. In the criminal sphere, they have contributed to several wrongful convictions, and in civil cases, they can protract disputes and reduce faith in the legal system. This has inspired a great deal of legal-psychological research studying expert biases and how to mitigate them. In response to the problem of biased experts, courts have historically employed procedural mechanisms to manage partiality, but have generally refrained from using exclusionary rules. Canada diverged from this position in 2015, developing an exclusionary rule in White Burgess Langille Inman v Abbott and Haliburton Co. In this article, we assembled a database of 229 Canadian bias cases pre- and post-White Burgess to evaluate the impact that this case had on the jurisprudence. The data suggests that White Burgess increased the frequency of challenges related to expert biases, however, did not noticeably affect the proportion of experts that were excluded. This suggests that the exclusionary rule introduced in White Burgess did not significantly impact the practical operation of expert evidence law, as it pertains to bias. We conclude by recommending that one way for courts to better address the problem of biased experts is to recognize the issue of contextual bias.

After a decade of courtroom battles and heated academic debate, the United States has entered an age where the scientific validity of deoxyribonucleic acid (DNA) evidence is not subject to serious dispute. The problem with DNA evidence is no longer one of validity, but one of proficiency. Two confounding variables in the DNA testing process weaken and often destroy DNA's powerfulness and usefulness in the courtroom: crime labs and juries.This Note proposes new and stringent standards for the admissibility of DNA evidence. The admissibility of forensic DNA evidence must be conditioned on its examination by a crime lab governed by uniform national standards. Such governing national standards must encompass every aspect of the forensic process, from chain of custody to DNA testing procedures, in order to ensure the reliability of DNA evidence. Implementing such a comprehensive national standard, however, only represents a first step toward solving the problem of DNA evidence in the courtroom. This step, however, fails to address the second problem facing the effective use of DNA in courtrooms: juries.

Within the legal system an assumption exists that witness testimonies should be independent of one another; however the evidence suggests that this is frequently not the case. Witnesses commonly discuss the event with each other. It is important to determine the effects of cowitness information on the validity of eyewitness testimony. It is generally recognized that discussion between witnesses can be detrimental; the possibility of false information (or information that the participant never saw) entering recall is a key concern. We review the prevalence of cowitness discussion, legal opinions about cowitness discussion, and finally experimental research investigating the effects of discussion on eyewitness memory. We also provide some suggestions of how to prevent cowitness discussion and contamination of testimony.
