Different Scripts, Different Casts: A Crime Script Analysis Indicating Intimate Partner Violence Is Not All the Same.

Crime script analysis was used to analyze intimate partner violence diversity by identifying variables significantly associated with different script tracks. Qualitative thematic analysis using official police administrative data from Queensland, Australia, was used to develop an intimate partner violence protoscript (n = 40), followed by quantitative hierarchical cluster analysis and cross-tabulations to examine diversity within scripts. Four diverse script tracks were identified: "escalating jealousy," "persistently possessive," "controlling victim agency," and "enduring argument." Intimate partner diversity exists with divisions based on statistically significant variables. Implications for situational crime prevention and the use of mixed methods for strengthening crime script analysis are discussed.

Evading Detection: Characteristics of Individuals With Extrafamilial Child Sexual Offences and Long Detection Lags.

Most child sex offending is unreported and undetected. Despite this, most research relies on the characteristics of those frequently detected and arrested. This study aims to address this disparity by examining a group of men convicted of child sexual abuse (CSA) offences with multiple victims and who evaded detection for long periods of time (n = 170). This sample was compared to a group of men caught quickly for CSA offences against multiple victims (n = 170). The two groups were compared on demographic, lifestyle, sexual deviancy, and criminogenic measures. Individuals with long detection lags had more child victims, including more pre-pubescent and male victims and commenced their sexual offending at a comparatively earlier age. Additionally, individuals with long detection lags were more likely to be non- Indigenous and to show specialization in their sexual offending. These findings have implications for identifying and managing high harm child sexual offenders who evade detection for long periods.

Evading Detection: What Do We Know about Men Charged with Extrafamilial Child Sexual Abuse following Delayed Detection?

Most child sexual abuse (CSA) remains unreported and undetected. Despite this, much of what we know about perpetrators of CSA is derived from samples of convicted CSA offenders. Significant knowledge gaps remain about those who have evaded detection. This study addresses this gap with an in-depth content analysis of the case files of ten convicted child sexual offenders (CSOs) with the longest detection lag, selected from a broader group (n = 349) of men incarcerated at the Massachusetts Treatment Center (MTC). Participants were examined on a range of offender characteristics including Adverse Childhood Experiences (ACEs), cognitive distortions, antisocial traits, indicators of pedophilia and Machiavellian or narcissistic traits, offense facilitating factors, and grooming behavior. A tentative profile emerged with the following characteristics: direct experience of childhood abuse, various cognitive distortions, specialized rather than versatile criminal history, pedophilic traits, Machiavellian traits, and engaging in a range of offense-facilitating behaviors including grooming. We provide insight into offenders who evade detection for CSA and set the foundation for further research to inform prevention strategies for law enforcement agencies and child-serving organizations.

Police are Influenced by Anchoring and Risk When Allocating Resources for Scenario-based Intimate Partner Violence Cases.

Sixty-six police officers were given four intimate partner violence (IPV) scenarios to rate for risk of future violence. At the start of the experiment, participants were provided with either a low-risk or high-risk "anchor" scenario of police attending an IPV incident. Next, participants were given three counterbalanced scenarios: high, medium, and low risk. Half the participants were given a structured professional judgment tool to guide their decisions. Participants given the low-risk anchor rated the following scenarios as being of greater risk than those given the high-risk anchor. Participants were consistent in identifying high-, medium-, and low-risk scenarios and the tool made no difference to these ratings. Participants were more confident in their higher risk judgments than their lower risk judgments. Officers distributed a disproportionately high amount of resources to the high-risk offenders and the results suggest that police officers can make decisions consistent with Risk-Need-Responsivity principles. However, anchoring effects and working in a context where violence is more severe and frequent has the potential to bias perceptions and make officers less sensitive to risk.

Investigative interviewing of youth with ADHD - recommendations for detective training.

Attention deficit hyperactivity disorder (ADHD) in youth can lead to a trajectory of early and repeated contact with the criminal justice system (CJS), where such youth face significant challenges due to the nature of their diagnosis and the lack of specialized detective training in this area. This article reviews Australian detectives' perceptions regarding contact with ADHD-affected youth, ongoing contact of such youth with the CJS, and the impact of ADHD on interviewing time efficiency and quality of information gathered. It explores detectives' perceived impact of ADHD on components of the Cognitive Interview (CI). It overviews detectives' perceptions regarding their own skill/ability, training availability and future training preferences regarding the interviewing of ADHD-affected youth. The authors highlight best practice in specialized detective training, as well as in working with ADHD-affected youth. Recommendations are made regarding the design features of a potential specialized training programme for detectives interviewing ADHD-affected youth.

Police perceptions of the impact that ADHD has on conducting cognitive interviews with youth.

Attention deficit hyperactivity disorder (ADHD) in youth witnesses, victims and suspects can significantly impact the investigative interviewing process. In this study, 102 Child Protection Investigation Unit (CPIU) detectives were asked to read four vignettes of adolescents being interviewed by police, two as witnesses and two as suspects, in which one witness and one suspect display ADHD-type behaviour. The detectives rated the degree to which the behaviour in each vignette would impact the interviewer's ability to use the 10 key components of the cognitive interview (CI). They perceived ADHD-type interviewee behaviour as significantly hampering the use of all 10 CI components. There is also a significant difference between the detectives' rated severity of each CI component; they rated Encourage Concentration, Mentally Recreate and Change Order as exerting the strongest impact on the interview process. Implications for police perceptions of training options, needs and preferences regarding interviewing youth with ADHD are discussed.

Want a Better Criminal Justice Response to Rape? Improve Police Interviews With Complainants and Suspects.

Achieving just outcomes in rape cases is difficult, but there are ways we can improve the investigation and prosecution of these crimes, now. We outline how targeting variables, within control of the criminal justice system, can improve the quality of information police obtain from interviews with complainants and suspects. We explore how, by preserving these accounts on video, the criminal justice process can better use this information to improve effective decision making from investigation through to criminal trial through to prevention.

An object cue is more effective than a word in ERP-based detection of deception.

Recent studies of deception have used a form of the guilty knowledge test along with the oddball P300 event-related potential (ERP) to uncover hidden memories. These studies typically have used words as the cuing stimuli. In the present study, a mock crime was enacted by participants to prime their episodic memory and different memory cue types (Words, Pictures of Objects and Faces) were created to investigate their relative efficacy in identifying guilt. A peak-to peak (p-p) P300 response was computed for rare known non-guilty item (target), rare guilty knowledge item (probe) and frequently presented unknown items (irrelevant). Difference in this P300 measure between the probe and irrelevant was the key dependent variable. Object cues were found to be the most effective, particularly at the parietal site. A bootstrap procedure commonly used to detect deception in individual participants by comparing their probe and irrelevant P300 p-p showed the object cues to provide the best discrimination. Furthermore, using all three of the cue types together provided high detection accuracy (94%). These results confirm prior findings on the utility of ERPs for detecting deception. More importantly, they provide support for the hypothesis that direct cueing with a picture of the crime object may be more effective than using a word (consistent with the picture superiority effect reported in the literature). Finally, a face cue (e.g., crime victim) may also provide a useful probe for detection of guilty knowledge but this stimulus form needs to be chosen with due caution.

The influence of belief that a car crashed on witnesses' estimates of civilian and police car speed.

The authors performed 2 experiments investigating the influence of the belief that a vehicle crashed on witnesses' estimates of the vehicle's speed. In Experiment 1, participants saw a video of a civilian car being driven, after which they were assigned to 1 of 2 conditions. The 1st group was told that the vehicle subsequently crashed; the 2nd group was not told that the vehicle crashed. The results indicted no differences between the 2 groups on a number of factors, including estimates of the vehicle's speed. Experiment 2 was identical except that the video showed a police car using flashing lights and sirens. Participants who had been told that the car had crashed overestimated speed, the likelihood of a crash, and the likelihood of someone being killed. Participants who were not told that the vehicle crashed estimated the speed of the vehicle accurately. Confidence in their estimates of speed was not significantly different between the 2 groups. Results are discussed with regard to police investigations of road accidents.
