Research and Development (‘R&D’) in forensic science currently focuses on innovative technologies improving the efficiency of existing forensic processes, from the detection of marks and traces at the scene, to their presentation in Court. R&D approached from this perspective provides no response to doubts raised by recent criminological studies, which question the effective contribution of forensic science to crime reduction, and to policing in general.Traces (i.e. forensic case data), as remnants of criminal activity are collected and used in various forms of crime monitoring and investigation. The aforementioned doubts therefore need to be addressed by expressing how information is conveyed by traces in these processes. Modelling from this standpoint expands the scope of forensic science and provides new R&D opportunities. Twelve propositions for R&D are stated in order to pave the way. 相似文献

Given the size and complexity of many digital forensic science device examinations, there is a need for practitioners to formally and strategically determine a course of conduct which allows them to undertake the most robust and efficient examination possible. This work outlines both the need for practitioners to have a digital evidence strategy (DES) when tackling any given examination scenario, how to construct one and the concerns which exist when no formal DES is in place. Approaches to DES development are examined and the context to which they should be deployed are analysed, with focus being on the use of DESs at the examination/processing stage of the investigative workflow. Finally, a ‘DES skeleton’ is offered to guide practitioners as they seek to create their own DES. 相似文献

With new typing techniques forensic scientists can characterise individuals at the fundamental level of their DNA. Variation between individuals at this level can be used to discriminate between them. Why this is so and how it is achieved is described in relatively simple terms for legal and medical practitioners who have no formal training in genetics. 相似文献

Forensic scientists are routinely faced with the problems of making decisions under circumstances of uncertainty (i.e., to perform or not perform a test). A decision making model in forensic science is proposed, illustrated with an example from the field of forensic genetics. The approach incorporates available evidence and associated uncertainties with the assessment of utilities (or desirability of the consequences). The paper examines a general example for which identification will be made of the decision maker, the possible actions, the uncertain states of nature, the possible source of evidence and the kind of utility assessments required. It is argued that a formal approach can help to clarify the decision process and give a coherent means of combining elements to reach a decision. 相似文献
