Building on the findings of a British Academy-funded project on the development of digital forensics (DF) in England and Wales, the purpose of this paper is to explore how triage, a process that helps prioritise digital devices for in-depth forensic analysis, is experienced by DF examiners and police officers in four English police forces. It is argued that while as a strategy triage can address the increasing demand in the examination of digital exhibits, careful consideration needs to be paid to the ways in which its set-up, undertaking and outcomes impact on the ability of law enforcement agencies to solve cases.

The methodological approach adopted here builds on the ethnographic turn in criminology. The analysis draws on 120 h of ethnographic observations and 43 semi-structured interviews. Observational data of the working DF environment at each location and a systematic evaluation of internal documents, organisational settings and police priorities helped refine emergent analysis threads, which were analytically compared between sites and against the testimonies of members of different occupational groups to identify similarities and differences between accounts.

The findings emphasise the challenges in the triage of digital exhibits as they are encountered in everyday practice. The discussion focusses on the tensions between the delivery of timely and accurate investigation results and current gaps in the infrastructural arrangements. It also emphasises the need to provide police officers with a baseline understanding of the role of DF and the importance of clearly defined strategies in the examination of digital devices.

This paper aims to bridge policy and practice through an analysis of the ways in which DF practitioners and police officers in four English constabularies reflect on the uses of triage in DF to address backlogs and investigative demands. Highlighting the importance of digital awareness beyond the technical remit of DF units, it offers new insights into the ways in which police forces seek to improve the evidential trail with limited resources.

In the last decade, Australia has seen a series of high‐profile criminal cases come under court and public scrutiny due to improper interviewing practices, prompting a need to review and revise training in interviewing skills. This pattern echoes that seen in the UK in the 1970s and 1980s. What followed in the UK was a plethora of research examining different aspects of police interviewing. To date, there has been limited research in Australia on interviewing suspects. The purpose of this paper is to provide insight into a large sample of current Australian police officers' attitudes and practices regarding investigative interviewing.

This study involved a survey of current police officers from the Queensland Police Service (n=2,769), collecting data on attitudes with current training and supervision, importance of investigative interviewing and operational skills and competence.

These are discussed in relation to the need for further systematic research into police interviews, improved training and the need for law enforcement organisations and agencies in Australia to implement organisational investigative interviewing strategies.

The paper shows that further systematic research is required to examine “operational” investigative interviewing practices (as opposed to perceptions) in Australia. Consideration also needs to be given to the development of investigative interviewing training frameworks that focus on the experience, skills and previous training of each officer. Moreover, interviewing needs to be recognised as a skill requiring regular maintenance, monitoring and evaluation.

This article aims to focus on the impact of the current austerity measures on UK public sector anti-fraud and financial crime investigative resource capacity building initiative developed over the years to tackle fraud against the public purse.

The article draws on secondary sources of data and available literature on fraud and financial crime.

Fraud is a challenge in the UK public sector but the cut-back on anti-fraud and financial crime investigative resources, given the scale of public sector fraud, the growing emphasis on accountability and the time of austerity with public money more exposed to fraud is arguably a back-door/u-turn policy on zero-tolerance approach in tackling public sector fraud and financial crime. There is the potential of this encouraging more fraud and financial crime against the public sector in the long term if measures are not taken to devise strategies for enhancing anti-fraud and financial crime investigative resource capacity.

The research implication for this article is that it opens an avenue for future studies to examine post austerity strategies for strengthening public sector anti-fraud and financial crime investigative resource strategies to deal with emerging fraud threats to UK public sector.

This article acts as a reference guide for policymakers to reflect on the long-term adverse impact of the austerity on anti-fraud and financial crime investigative resource capacity and capability in tackling fraud public sector fraud.

The paper attempts to present an alternative lens to examining the scale of UK public sector fraud problem rather than relying on headline story of declining fraud in UK.

The present study aims to examine the scope and contribution of behavioural investigative advice (BIA) reports from the National Crime Agency (NCA).

The 77 BIA reports reviewed were written between 2016 and 2021. They were evaluated using Toulmin’s (1958) strategy for structuring pertinent arguments, current compliance with professional standards, the grounds and backing provided for the claims made and the potential utility of the recommendations provided.

Consistent with previous research, most of the reports involved murder and sexual offences. The BIA reports met professional standards with extremely high frequency. The 77 reports contained a total of 1,308 claims of which 99% were based on stated grounds. A warrant and/or backing was provided for 73% of the claims. Most of the claims in the BIA reports involved a behavioural evaluation of the crime scene and offender characteristics. The potential utility of the reports was judged to be 95% for informative behavioural crime scene analysis and 40% for potential new lines of enquiry.

The reports should serve as a model for the work of behavioural investigative advisers internationally.

To the best of the authors’ knowledge, this is the first study to systematically evaluate BIA reports commissioned by the NCA; it adds to previous similar studies by evaluating the largest number of BIA reports ever reviewed, and uniquely provides judgement of overall utility.

This paper addresses the clearance of aggravated assaults (AAs). Specifically, the authors consider variations in these clearances over time for large agencies and test which crime, investigation and agency factors are associated with the likelihood of clearance by arrest or exceptional means. In doing this work, they seek to extend the understanding of how police can improve their investigations and ability to solve serious offenses.

Using case, investigative and organizational data collected from seven large police departments selected on the basis of their trajectory of index crime clearances, and measures of case characteristics, investigative effort and organizational best practices, this paper uses descriptive and inferential statistics to analyze AA investigations and case clearance.

Key findings include the following: trajectories of AA clearance vary across large agencies and covary with a measure of organizational best practices, and the relationship between investigative effort and case clearance can depend on organizational practices. The authors find that measures of investigative effort are either not related to case clearance or there is a negative association.

Now that police researchers have a better understanding of AAs and their investigations, they need to test how this knowledge can be used to improve the quality of police investigations. Tests, preferably multi-agency randomized control trials, of new investigative strategies and organizational practices are needed.

This research is original in that it uses a multi-agency sample and crime, investigation and organizational measures to understand AA clearance.

High-stake crime investigations include cases such as murder and rape. The purpose of this paper is to outline the components of an interview strategy for suspects. In the UK, these interviews are often managed by Interview Managers who are tasked with developing effective interview strategies with the aim of ensuring all parties involved in the interview process are dealt with ethically and legally using research-based methods.

This practitioner paper is based on the experience of the authors who have provided advice and support during high-stake crime investigations both nationally and internationally using the research-base to underpin their practical advice.

To be effective, a suspect strategy constructed by an Interview Manager in high-stake crime investigations should be designed within a framework that covers the provision of strategic advice on research-based interview processes including: co-ordination of the interview process, monitoring of the interview process and evaluation of the interview process.

To ensure interviews are effectively managed during high-stake crime investigations, the suspect interview strategy must be developed to a professional standard to allow for quality assurance and outside scrutiny.

To the best of the authors’ knowledge, this is the first published paper that outlines the nature of a suspect strategy that is based on a Framework consistent with elements of the UK National Occupational Standards.

This paper aims to evaluate how five Operation Soteria Bluestone (OSB) participating forces integrated principles of procedural justice and proactive disruption of offending into their investigations, specifically during the closing stages of a case when considering exit strategy and longer-term prevention.

A mixed-methods approach was taken, including 32 semi-structured interviews with officers and 59 case reviews of recent rape and serious sexual offences (RASSO). Data analysis methods included qualitative thematic analysis of interviews, while data from reviewed case logs was extracted and analysed using a bespoke case review tool.

Increased workloads, preparation of evidence and relational/communication difficulties with the crown prosecution service (CPS) were identified as barriers to implementing long-term disruption options. Dedicated resourcing, training and support are needed to promote suspect-focused investigative strategy and wider uptake of long-term disruption methods. Early investigative approach was also found to have “snowball” effects on suspect exit strategy, with initial lack of suspect focus and preoccupation with victim credibility, impeding consideration of long-term disruption and safeguarding options. Findings also point to a disparity between promising practice in relation to procedural justice for victims and (a relative lack of) proactive policing of repeat suspects.

The study represents a novel contribution to research on policing RASSO, illustrating the scale and nature of the obstacles to changing how these offences are investigated, even when under intense scrutiny from policy makers. It also highlights how increased organisational investment and support is linked to positive changes in practice in some forces.

Purpose – Good investigative sociology and high-quality investigative journalism are not just the same but they are close relatives. For both professions, getting under the surface soil of social life, digging deeply into and making coherent sense of the social experience of others, and translating those findings and interpretations into a universal language for widespread consumption are hugely challenging tasks. Understanding the difference and similarities regarding how sociologists and investigative journalists go about this task raises fundamental philosophical, epistemological, ethical, methodological, theoretical and practical concerns, the outline considerations of which are all featured in this chapter.

Design/methodology/approach – Drawing upon more than three decades of investigative research experience in the field and the original and the innovative personal scholarship that this has yielded, the chapter offers students a map reader's guide of how to navigate a way through the complex, challenging and sometimes hazardous labyrinth of investigative qualitative research.

Originality/value – In addition to offering a ‘how to’ primer for thinking about and doing investigative-qualitative sociology, the chapter also offers advice on how to survive the experience and authoritatively tell the tale well to the widest possible audiences.

The purpose of this paper is to provide the reader with senior investigating officer (SIO) perspectives of their understanding of gang-related homicide and associated investigative challenges.

A phenomenological design was utilised in this study. In sum, 15 SIOs from the Metropolitan Police Service were interviewed using a semi-structured interview and analysed using thematic analysis.

It was found that the original typology of “gang homicide” might be too narrow and focus should be paid to “gang-related homicide”, characterised via motive behind the offence. This type of homicide exhibited specific characteristics (e.g. violent nature, large potential scene and pool of suspects) and investigative challenges which made it different from other types of homicide (e.g. complexity, need for more resources, managing unwilling witnesses, managing media interest, specific evidence challenges, need for thorough risk assessments). The need for expertise in the deployment of officers was highlighted and related to the desire for more continuing professional development (CPD).

Gang-related homicide is especially challenging, but due to its volume, SIOs in London developed a sort of “muscle memory” – something that other police services do not have, even though the “gang problem” is spreading outside of metropolitan areas. Support for changes (e.g. in the utility of community impact assessment) and non-standard procedures (e.g. consideration of covert operations early on) should be discussed in further training and manual development. More attention needs to be paid to the synthesis of experience, expertise and science, SIOs being especially interested in debriefs and CPD opportunities. Multi-agency training is key for homicide investigators, relating to the complex nature of gang-related homicide and relevant safeguarding issues. Resourcing is a clear issue relating to the increase in gang-related homicide, as well as its investigation.

This is the first research into investigative challenges of gang-related homicide in England and Wales, and the findings can be utilised by all police services who may be dealing with gangs in their area. The findings can also support calls for change and development within services.

This paper aims to examine the history of data leaks and investigative journalism, the techniques and technology that enable them and their influence in Australia and abroad. It explores the ethical and professional considerations of investigative journalists, how they approach privacy and information-sharing and how this differs from intelligence practice in government and industry. The paper assesses the strengths and limitations of Collaborative Investigative Reporting based on Information Leaks (CIRIL) as a kind of public-facing intelligence practice.

This study draws on academic literature, source material from investigations by the International Consortium of Investigative Journalists and the Organised Crime and Corruption Reporting Project, and a survey of financial crime compliance professionals conducted in 2022.

The paper identifies three key causal factors that have enabled the rise of CIRIL even as traditional journalism has declined: the digital storage of information; increasing public interest in offshore finance and tax evasion; and “virtual newsrooms” enabled by internet communications. It concludes that the primary strength of CIRIL is its creation of complex global narratives to inform the public about corruption and tax evasion, while its key weakness is that the scale and breadth of the data released makes it difficult to focus on likely criminal activity. Results of a survey of industry and government professionals indicate that CIRIL is generally more effective as public information than as an investigative resource, owing to the volume, age and quality of information released. However, the trends enabling CIRIL are likely to continue, and this means that governments and financial institutions need to become more effective at using leaked information.

Over the past decade, large-scale, data-driven investigative journalism projects such as the Pandora Papers and the Russian Laundromat have had a significant public impact by exposing money laundering, financial crime and corruption. These projects share certain hallmarks: the use of human intelligence, often sourced from anonymous leaks; inventive fusion of this intelligence with data from open sources; and collaboration among a global collective of investigative journalists to build a narrative. These projects prioritise informing the public. They are also an important information source for government and private sector organisations working to investigate and disrupt financial crime.
