Forensic science is increasingly relied on by police and the courts to exonerate the innocent and to establish links to crime. With this increased reliance the potential for unjust outcomes increases, especially in serious matters for two reasons. The more serious the matter, the more likely that evidence mishandling can lead to wrongful imprisonment, and the more likely the personnel involved will be multi-disciplinary (police, medicine, law, forensic science), and multi-organisational (Health, Justice, private legal/medical, police). The importance of identifying effective multi-organisational interactions was highlighted in the recent wrongful imprisonment of an Australian male for a sexual assault he did not commit. One factor that led to this unjust outcome was the justice silo effect: where forensic practitioners from different agencies operate in isolation (rarely communicating or sharing information/ knowledge). In this paper we discuss findings from the Interfaces Project designed to assess the extent of the justice silos within Australia. We interviewed 103 police, forensic scientists, lawyers, judges, coroners, pathologists and forensic physicians Australian-wide. Five main themes were identified in the data: the silo effect was only partial and in each jurisdiction some form of inter-agency communication was actively occurring; inter-agency meetings were more common in homicide than sexual assault cases; forensic physicians were semi-invisible; there had been considerable momentum over the past ten years for practice improvement groups, and; practitioners gain more benefits than pitfalls from interagency information-sharing. Based on these findings, five recommendations are made for improving practice. [ABSTRACT FROM AUTHOR]

There is limited information available about the impact of chemical trace evidence and it has tended to be anecdotal and mostly pertaining to court outcomes. Very little is known about the use of chemical trace evidence by police investigators or the impact that this evidence form has on criminal investigations. This survey, which was conducted in Victoria, Australia, was aimed at addressing these inadequacies by capturing information from police investigators about: (i) the purpose of using chemical trace and other forensic services; (ii) the expectation of what value forensic services would provide; (iii) the actual impact of forensic evidence in specified cases; and (iv) the general perceptions of forensic science. Police officers who were the lead investigators in a sample of criminal investigations were selected as the subjects for this survey. Each of the sample cases included chemical trace evidence and many of the cases also included other forms of forensic evidence. The police investigators indicated that they use chemical trace evidence with the expectation that it will assist decision-making in their investigations and contribute to building a case for court. Survey responses indicated that chemical trace evidence can impact on multiple stages of a case and that this form of evidence can play a part in guiding police investigators in making decisions about how their cases progress through the criminal justice system. It was found that an important aspect of the impact of chemical trace evidence can involve connections with other forensic and non-forensic evidence in the cases. The provision of preliminary results, prior to the formal written reports that are issued for use in court, enables chemical trace evidence to contribute timely support to investigations. The findings of this survey study contradict prevailing perceptions that the contribution of chemical trace evidence is limited to the presentation of evidence in court. [ABSTRACT FROM AUTHOR]

The provision of forensic science services in volume crime investigations works most successfully as a partnership between police agencies and external forensic laboratories as opposed to a client/provider model where unlimited demand ignores finite resources. The principles of Lean Six Sigma have been applied in various laboratories to improve workflow through identification of wasteful work practices. These strategies are aimed at process optimisation through the application of triaging, a concept that has rarely been studied yet referenced strongly in the literature. The South Australia End to End 90-Day Trial: facilitating quicker justice through timely evidence processing, is a collaborative approach between South Australia Police and Forensic Science South Australia. This trial applied evidence-based policing principles, a law enforcement philosophy that uses research undertaken with scientific processes to inform law-enforcement decision-making. The results demonstrate how a review of processes and the removal of non-value adding activities can improve service delivery while not exhausting those ‘finite resources’. [ABSTRACT FROM AUTHOR]
