The forensic psychiatrist of the future

The rate of change in scientific knowledge and the growing psychiatric sophistication of attorneys and courts have made it increasingly difficult for forensic psychiatrists to retain proficiency in the full spectrum of potential professional activities. As the consumers of forensic services become more sophisticated, forensic psychiatrists have an increasing need to become scientifically informed and a decreasing need to become legally informed. Traditional training in forensic psychiatry, which emphasizes clinical, legal, and institutional knowledge and experience, gives short shift to behavioral science and other technical knowledge that can enhance the validity of forensic assessments and their value to the legal system and society. Forensic psychiatrists can best respond to these changes and maximize the value of their assessments by narrowing their focus to some subset of the four branches of the discipline: criminal behavior, mental disability, forensic child psychiatry, and legal aspects of psychiatric practice. Maximal proficiency in each of these four branches requires a greater depth of knowledge and experience than was once sufficient among those who practiced in all four areas. Fellowship training programs and professional organizations should lead forensic psychiatry into the twenty-first century by organizing their efforts along these four parallel tracks.     

Is crime scene examination science, and does it matter anyway?

This short piece aims to assess the kind of data collected by Crime Scene Examiners (CSEs), and to discuss whether this collection constitutes a scientific process. It also seeks to examine the balance of roles performed by the CSE, between data gatherer and investigator. The piece also aims to conclude on whether a clearer understanding of the structure of data collected by CSEs might be of some practical use in developing a greater understanding of the architecture of knowledge that forensic science as a whole relies upon. As a piece of work it is unapologetically theoretical in its perspective, and seeks to prompt further discussion regarding the structure of scientific knowledge, and any relevance this might have to its application in a forensic context. Ultimately, it seeks the inclusion of the processes of data gathering performed largely by CSEs within the wider processes of forensic science.     

The scientific basis for human bitemark analyses--a critical review.

This article presents a discussion of the scientific basis for human bitemark analyses. Using a review of the literature, the major areas of contention within the field are assessed: including the accuracy of bitemarks on skin, the uniqueness of the human dentition, and analytical techniques. The review revealed a lack of valid evidence to support many of the assumptions made by forensic dentists during bitemark comparisons. The new level of judicial scrutiny of such scientific evidence is likely to emphasise this lack of knowledge upon which bitemark analysis relies. The authors call for a more scientific and evidence-based approach to forensic dental research.

Sexual assault examinations and forensic medical samples

Recent studies and a review in the United States have identified that tens of thousands of used but untested sexual assault examination kits containing medical examination specimens are to be found in police station evidence rooms, forensic science laboratories, hospitals and rape crisis centres. A 2007 survey undertaken by the National Institute of Justice in the United States explored some of the reasons why forensic specimens are not tested by forensic science laboratories. Many of these relate to lack of knowledge on the part of investigators as to how scientific information can assist the investigation process, even if not used subsequently at trial. Cost factors and laboratory casework overload were also identified as significant. For the medical practitioner, the lack of testing poses issues that include quality management of the forensic medical examination and informed consent in a setting requiring the balancing of public and private benefits for the examinee. Limiting scientific testing, even with intelligence-led triaging of sample testing, could have an adverse effect on both prosecution and defence decision-making and ultimately could adversely affect trial outcomes.     

试论鉴定意见的可诉性———兼论鉴定意见争议的解决

司法鉴定意见是司法鉴定人对诉讼涉及的专门性问题的个人认识和判断,不仅受到仪器设备、鉴定方法以及实验室条件等客观因素的制约,也会受到司法鉴定人的知识水平、业务能力和实践经验等主观因素的影响。因而,对于同一专门性问题可能会出现不同的鉴定意见,其可靠性和科学性也无可避免会受到当事人的质疑。通过对司法鉴定的属性、可诉性的审判实践、法理上的分析以及我国现行法律对一些法律行为的可诉性规定等方面进行探讨,以寻找司法鉴定意见是否可诉的答案以及司法鉴定意见争议的解决机制。     

科学证据可采性规则研究

科学证据是运用科学知识和科学方法对证据分析所得的判断意见。因此,科学证据属于意见性证言。为防止不可靠的科学证据对法庭的误导,英美法系国家建立了科学证据可采性规则,包括相关性规则、必要性规则、专家证人资格规则、排除规则、可靠性规则。美国科学证据可靠性规则经历了从Frye规则、Daubert规则到修订后的《联邦证据规则》702条的嬗变。我国对鉴定意见的审查主要限于相关性和合法性的审查。由于缺少对鉴定意见可靠性审查的指导与限制,导致了错误裁决的风险。本文提出确立鉴定意见科学可靠性规则的构想,以利于法官排除错误的鉴定意见,同时有助于法庭科学实验室的管理与制度完善,促使法庭科学实验室更严谨更科学地为法庭提供优质的法庭科学服务。

DNA evidence in South Africa: Lessons learned to date

A trend was noted over the past 15 years in the South African courts. This trend has a multi-factorial origin and highlights the problems faced in the use of forensic science evidence in court. Although there have been improvements on how DNA evidence is gathered and presented in court, due to the fact that certain cases have been contested at the DNA evidence level, multiple issues remain that have not yet been addressed when DNA evidence is submitted to court. These issues include: accreditation, regulation of the forensic science profession, continued education, training of court officials, quality assurance, biased testimony, lack of transparency with regard to processes and procedures followed in the forensic community, incorrect interpretation of DNA evidence, lack of scientific knowledge (including the scientific method) by DNA experts, awareness by the legal profession and an over emphasis on the prosecuting perspective. These same aspects continue to plague current cases. Despite the above, the window of opportunity to address the above has not yet passed. However, it will take continuous and concerted efforts from the scientific and legal professions to bring about the appropriate change to facilitate justice for all in South Africa.     

Forensic medicine and criminalistics

The supplementary designation "criminalistics" in the title of certain forensic medical institutes in the first half of this century is to be regarded as a reaction to faulty developments in our specialty, which almost led to the elimination of forensic medicine as an independent scientific discipline in the 1960s. The ability to think in terms of criminalistics and the corresponding working procedures has always been a crucial precondition for the forensic physician, since forensic medicine is the application of medical knowledge for juridical purposes. Forensic medicine originated with the appraisal of cases of violent death by doctors, i.e., reconstruction of the facts in the case. To use the term "criminalistics" in the form of a supplementary designation is thus not required. An attempt is nevertheless made to define "medical criminalistics" as a small but important component of criminalistics. They are subdivided into two phases: the first part begins at the scene of the crime or the place of discovery (local evidence). Here, the trained eye of the forensic physician is indispensable to the criminal investigation department and the prosecutor. Medical criminalistic thinking and working procedures continue at the autopsy. Here, forensic autopsy differs from that practiced by the pathologist. Without knowledge of the situation at the discovery location, the forensic physician runs the risk of not recognizing facts that are important for reconstruction and thus becoming a "destroyer of clues". The second part of medical criminalistics is the actual detection of medical clues, i.e., the investigation of medical clues with special methods, including histological and toxicological investigations.(ABSTRACT TRUNCATED AT 250 WORDS)     

Effective use of forensic science in volume crime investigations: Identifying recurring themes in the literature

New scientific, technological and legal developments, particularly the introduction of national databases for DNA and fingerprints, have led to increased use of forensic science in the investigation of crime. There is an assumption, and in some instances specific assertions, that such developments bring improvements either in broad criminal justice terms or more narrowly in terms of economic or practical efficiencies. The underlying presumption is that the new technological opportunities will be understood and effectively implemented. This research investigates whether such increases in activity have also been accompanied by improvements in the effective use of forensic science. A systematic review of thirty-six reports published (predominantly in England and Wales) since the 1980s, which have considered the use of forensic science in the investigation of volume crimes, was carried out. These reports have identified a number of recurrent themes that influenced how effectively forensic science was used in investigations. The themes identified included forensic knowledge and training of investigators, communication and information exchange between specialists and investigators, timeliness of forensic results, interagency relationships and deployment of crime scene examiner resources. The research findings suggest that these factors continue to hinder the effective use of forensic science despite technological advances and this paper considers their potential causes.     

Forensic pathology on the threshold of the 21st century and the need for harmonization of current practice and training: the Greek concept

Our era is characterized by the globalization of crime. This poses to all democratic countries the urgent need to reform their systems to fight crime more effectively. Forensic sciences remain an integral part of the system against crime. This scientific field can also offer valuable knowledge regarding the causes of death. From an epidemiologic point of view, this can result in better organization of prevention measures for the best interests of the community. Harmonization and collaboration in the operation of the various forensic systems that presently exist around the world is of paramount importance if effective prevention of crime and other causes of death in contemporary reality is to be achieved. In addition, revision of training in forensic pathology and forensic sciences is essential if harmonizing the forensic systems is to succeed. This report provides an overview of the wide variation in the operation of forensic systems and training. Emphasis is given to the importance of their harmonization, and an attempt is made to explore principles that may contribute along these lines. Finally, the authors provide proposals for revision of the training system in forensic pathology in Greece.     

刑事鉴定制度修改的背景、争议及解读

《刑事诉讼法》在鉴定问题上进行了大幅度地修改,改变了鉴定作为证据种类的名称,删除了"省级人民政府指定的医院"的规定,增加了对鉴定人出庭作证及其人身权利保障等内容,其进步意义应当是肯定的。然而,《刑事诉讼法》有关鉴定修改触及的内容均需要从修改的缘故、争议问题被修改的程度以及执行中可能遇到的障碍等方面予以理论分析与诠释,以便对此问题有一个科学的认识与理解。     

Can Handedness be Determined from Skeletal Remains? A Chronological Review of the Literature

Abstract: Research indicates that considerable bilateral asymmetry exists in the skeletons of primates, including humans. The published literature suggests that although this asymmetry may be influenced by handedness, it reflects other factors as well. Although exact statistics of handedness in the modern population are not available because definitions of handedness vary greatly, it is known that we live in a predominantly right‐handed world. This knowledge makes the determination of handedness in forensic cases not as paramount in importance as other determinations. Review of the published scientific evidence clearly reveals that observations and measurements of the human skeleton cannot determine handedness with the degree of confidence needed for forensic applications.

How do forensic scientists learn to become competent in casework reporting in practice: a theoretical and empirical approach

In their day-to-day work, carrying out complex tasks, forensic scientists use a combination of explicit, codified standard operating procedures and tacit knowledge developed through their ongoing practice. We show that tacit knowledge is an integral part of the activities of expert forensic science practitioners who continually add to their knowledge repertoire by engaging other scientists through communities of practice. We wish to shed fresh light on the gaining of tacit knowledge by forensic scientists during their apprentice formative years, termed as legitimate peripheral participation. In quantifying tacit knowledge exchanges, we use social network analysis, a methodology for the analysis of social structures, to map relational knowledge flows between forensic scientists within communities of practice at the Forensic Science Laboratory, Ireland. This paper sheds light on the importance of tacit knowledge within the training regime of forensic scientists and its recognition as equal to the part played by explicit knowledge.     

An exercise in scientific problem-solving: Illustrating the utility of the principles of the Sydney Declaration

In forensic science, scientific problem-solving is characterized by the recognition of traces as part of iterative reasoning processes to assign meaning to those traces in order to interpret and reconstruct events. Through a set of fundamental principles, the Sydney Declaration presents a foundation of forensic science through the lens of a scientist. The distinction between a scientist and a technician may require clarification—where a prototypical technician follows a prescribed set of ‘standard operating procedures’ and may be limited in the interpretation of the resultant data, the scientist utilizes knowledge, skills, experience and imagination to identify the issue at hand and develop lines of inquiry for testing and interpretation. This case report draws on the Sydney Declaration in order to highlight the importance of learning about events from careful consideration of both obvious and less obvious traces. A case involving the assault of a police officer is examined to illustrate the use of the Principles: the problem originally defined by investigators at the scene and later by prosecutors resulted in incorrect analysis and interpretation of traces, hampering efforts at an accurate reconstruction of events. This exercise serves to demonstrate that in order to engage in scientific problem-solving, it is necessary to apply observation and reasoning in forensic investigations in order to yield an outcome that can be clearly articulated. The overarching goal is to support the drive to improve forensic science practice, education, and research through a case illustrating the value of the principles of the Sydney Declaration.     

法医毒物鉴定结果科学表述模式的思考

法医毒物鉴定报告是毒物鉴定结果的表述模式。通过对国内外毒物鉴定报告形式和内涵的比较分析,认为我国现行按照《司法鉴定程序通则》规定出具的通用型的毒物鉴定报告尚不够专业、严谨、科学、充分,由于毒物鉴定报告的简约性和模糊性,证据的可靠性、科学性尚存在质疑,毒物分析结果的有效、充分利用尚不能实现。据此,提出毒物鉴定结果表述模式的建议。     

Combination of Face Regions in Forensic Scenarios

This article presents an experimental analysis of the combination of different regions of the human face on various forensic scenarios to generate scientific knowledge useful for the forensic experts. Three scenarios of interest at different distances are considered comparing mugshot and CCTV face images using MORPH and SC face databases. One of the main findings is that inner facial regions combine better in mugshot and close CCTV scenarios and outer facial regions combine better in far CCTV scenarios. This means, that depending of the acquisition distance, the discriminative power of the facial regions change, having in some cases better performance than the full face. This effect can be exploited by considering the fusion of facial regions which results in a very significant improvement of the discriminative performance compared to just using the full face.
