The bulk of the homicide research to date has focused on male offending, with little consideration given to women's offending and in particular, their constructions within the courtroom following a homicide-related charge. This thesis examines, in detail, nineteen homicide cases finalised in the Queensland Supreme Courts between 01/01/1997 and 31/12/2002, in order to document and discuss the various legal stories available to women who kill. Predominantly, two “stock stories” are available within the court. The first, presented by the defence, offers the accused woman a victimised position to occupy. Evidence of victimisation is made available through previous abuse, expert testimony from psychologists and psychiatrists, challenges to her mental health, or appeals to her emotional nature. The second stock story, presented by the prosecution, positions the accused woman as angry, full of revenge, calculating and self serving. Such a script is usually supported by witnesses, police evidence, and family members. This thesis examines these competing and contradictory scripts using thematic discourse analysis to examine the court transcripts in detail. It argues that the "truth" of the fatal incident is based on one of these two prevailing scripts. This research destabilises the dominant script of violent female offending in the feminist literature. Most research to date has focussed on explaining the circumstances in which women kill, concentrating attention on the victimisation of the violent offending woman and negating or de-prioritising any volition on her part. By analysing all transcripts of women whose trials were held within the specified period, this research is able to demonstrate the stories used to describe their complex offending, and draw attention to the anger and intent that can occur alongside the victimisation.

Les chercheurs s’étant penchés sur les facteurs influençant la décision du suspect de confesser son crime ont mis en évidence que deux facteurs sont principalement influents : la force de la preuve (Des Lauriers-Varin et St-Yves, 2006; Moston et al., 1992) et la conduite de l’enquêteur (Holmberg et Christianson, 2002; Kebell et al., 2005). Par contre, les contradictions entre ces études ont apporté davantage de confusion que de réponses à la pratique. Cette étude vise donc à explorer l’incidence de ces deux facteurs sur l’inclination du suspect à confesser son crime et les possibles interactions entre eux. Pour ce faire, 50 enregistrements vidéo d’interrogatoires d’homicide furent visionnés et les données furent soumises à des analyses statistiques et qualitatives. Les résultats d’une régression logistique démontrent que la conduite de l’enquêteur est le facteur prédominant pour prédire l’obtention d’aveux du suspect en contrôlant pour l’effet des variables statiques et de la preuve. Également, les résultats mettent en évidence qu’en augmentant les attitudes et comportements associés à une conduite « positive », l’enquêteur augmentait les probabilités d’aveux du suspect. De plus, les résultats indiquent que l’augmentation du nombre d’éléments de preuves est associée à une plus grande démonstration de « rapport de force » de la part de l’enquêteur. Les résultats sont discutés en relation à l’effet des principaux facteurs sur les schémas et dynamiques prenant place entre l’enquêteur et le suspect.

This paper sets out to explore the views and attitudes of police officers in the Greater Belfast area, concerning the process and use of video taped interviews with child witnesses, subsequently used as court evidence in child abuse cases. The information was collected by means of a postal questionnaire, completed by police officers who had all experienced joint interviews with social workers of child witnesses. With the increased use of video evidence as an alternative to the distressing experience of a child appearing in court to give evidence, the research findings and conclusions provide clear messages about future developments both nationally and internationally.

This article documents the impact of a police crackdown on a street heroin market in a suburb of Melbourne, Australia, as perceived by individuals involved in the market. While our data suggest that ‘Operation Clean Heart’ achieved its objective of reducing the visible aspects of this street drug scene, they also imply that the drug market rapidly adapted to its new conditions and that the impact of the operation was essentially superficial and temporary. In addition, we contend that the operation had numerous (unintended) negative consequences, some of which are potentially harmful to public health. Negative outcomes implied by our data included the partial displacement of the drug scene to nearby metropolitan areas; the discouragement of safe injecting practice and safe needle and syringe disposal; and more frequent occurrences of violence and fraud. These outcomes may outweigh the perceived positive impacts, which were achieved at significant public expense. We conclude that police crackdowns are inappropriate responses to illicit drug problems; instead, in line with longstanding Australian policy, approaches which incorporate and balance demand reduction, supply reduction and harm reduction principles should be followed.

This study investigated the usefulness of a computer program designed to assess young children's understanding of words that may be relevant to an investigative interview about assault. Forty-one police officers conducted two interviews with five- to six-year-old children (one was conducted with the program and one without). The program's effectiveness was based on the interviewers' ratings of the usefulness of the program as well as three independent indices of interviewer-child rapport. Overall, the police officers perceived the program to be an extremely useful pre-interview assessment. However, the program had little impact on the officers' style of questioning and the nature of the children's responses. The implications of these findings are discussed.

The Fourth Amendment prohibits unreasonable searches and seizures in criminal investigations. The Supreme Court has interpreted this to require that police obtain a warrant prior to search and that illegally seized evidence be excluded from trial. A consensus has developed in the law and economics literature that tort liability for police officers is a superior means of deterring unreasonable searches. We argue that this conclusion depends on the assumption of truth-seeking police, and develop a game-theoretic model to compare the two remedies when some police officers (the bad type) are willing to plant evidence in order to obtain convictions, even though other police (the good type) are not (where this type is private information). We characterize the perfect Bayesian equilibria of the asymmetric-information game between the police and a court that seeks to minimize error costs in deciding whether to convict or acquit suspects. In this framework, we show that the exclusionary rule with a warrant requirement leads to superior outcomes (relative to tort liability) in terms of truth-finding function of courts, because the warrant requirement can reduce the scope for bad types of police to plant evidence

This article presents an analysis of the discursive construction of evidence in an English police interview with a rape suspect. The analytic findings differ from previous research on police–suspect interview discourse, in that here the interviewers actively lead an interviewee to produce defence evidence. The article seeks to make the following contributions: (i) it demonstrates the interactional mechanisms through which the interviewers co-construct the interviewee’s own version of events, and highlights the potential legal ramifications by focusing on the construction of one key evidential aspect, namely, consent; (ii) it lends weight to the hypothesis that interviewer agendas are strongly determinative of interview outcomes in terms of the evidential account produced, while making the important new contribution of showing that this is not simply a case of police interviewers being inevitably prosecution-focused; and (iii) it aims to provoke further investigation into the significance of interviewer discursive influence in cases where consent is at issue, against a backdrop of increasing numbers of rape cases being discontinued by the police at this early stage of the criminal justice process.

Police investigators rely heavily on eliciting confessions from suspects to solve crimes and prosecute offenders. Therefore, it is essential to develop evidence-based interrogation techniques that will motivate guilty suspects to confess but minimize false confessions from the innocent. Currently, there is little scientific support for specific interrogation techniques that may increase true confessions and decrease false confessions. Rapport building is a promising possibility. Despite its recommendation in police interrogation guidelines, there is no scientific evidence showing the effect of rapport building in police interrogations. The current study examined, experimentally, whether using rapport as an interrogation technique would influence participants’ decisions to confess to a wrongdoing. It was hypothesized that building rapport with participants would lead to more true confessions and fewer false confessions than not building rapport. One hundred and sixty nine undergraduates participated in the study. Participants worked on logic problems together and individually, with a study confederate. The confederate asked half of the participants for help in one of the individual problems – effectively breaking the rules of the study. After working on these problems, a research assistant playing the role of interviewer came into the room, built rapport or not with participants, accused all participants of cheating by sharing answers on the individual problems, and asked them to sign a statement admitting their guilt. Results indicated that guilty participants were more likely to sign the confession statement than innocent participants. However, there were no significant differences on participants’ confession decisions based on the level of rapport they experienced. Results do not provide support for the hypothesis that building rapport increases the likelihood of obtaining true confessions and decreases the likelihood of obtaining false confessions. These findings suggest that, despite the overwhelming recommendation for the use of rapport with suspects, its actual implementation may not have a direct impact on the outcome of interrogations.
