Over the last five years, and especially since the formation of the Vulnerability, Resilience and Policing Research Consortium (VRPRC) in 2014, we have noticed an increasing focus on the intersections between policing and vulnerability—from the perspectives of scholars and policing organisations. This collection brings together scholars aligned with VRPRC, many of whom have collaborated with police practitioners in the development, implementation or evaluation of the work discussed in these chapters. Building strong police–academic partnership underpins the critical conversations we have within VRPRC. These critical conversations are important if we are to address the vulnerability that arises in the policing process. The editors would like to acknowledge the patience and perseverance of our contributors. Most of the work presented here was initially developed for a 2016 special edition of the Journal of Criminological Research, Policy and Practice (on Vulnerability and the Criminal Justice System), which saw us with a number of papers that could not be included due to word limit. Clustered at the front end of the criminal justice system, and with a particular focus on policing practices, these chapters formed the initial basis for the scope and structure of this book.
