“What you say in the lab, stays in the lab”: A reflexive thematic analysis of current challenges and future directions of digital forensic investigations in the UK

Abstract

Despite digital evidence nowadays playing a major role in criminal investigations and being intrinsic to almost every criminal trial, research in digital forensics (DF) and national approaches to digital evidence in relation to investigating officers and court personnel remain almost non-existent. This research seeks to remedy this issue by qualitatively examining the accounts and experiences of 16 digital forensic investigators (DFIs) in England and Wales who took part in semi-structured interviews. We analyzed the data using a reflexive thematic analysis and identified four overarching themes: (i) Navigating tensions with investigating officers (that has a subtheme of ‘Tensions with legal professionals and challenges navigating court theatrics’) (ii) The psychological, emotional, and existential challenges confronted by DFIs; (iii) Identifying the potential and pitfalls of automation and AI in DF and (iv) The centrality of academia in the advancement of DF (that has a subtheme of ‘Validation of tools as a crucial step in digital forensics’). These new findings reveal that DFIs encounter significant demands to perform well and are continuously overburdened while juggling many roles. This research serves as a pivotal starting point for broader discussions.
