This book goes beyond other police leadership books to teach practitioners how to think about policing in a structured way that synthesizes criminological theory, statistics, research design, applied research, and what works and what doesn’t in policing into Mental Models. A Mental Model is a representation of how something works. Using a Mental Model framework to simplify complex concepts, readers will take away an in-depth understanding of how cognitive biases affect our ability to understand and interpret data, what empirical research says about effective police interventions, how statistical data should be structured for management meetings, and how to evaluate interventions for efficiency and effectiveness. While evidence-based practice is critical to advancing the police profession, it is limited in scope, and is only part of what is necessary to support sustainable change in policing. Policing requires a scientifically based framework to understand and interpret data in a way that minimizes cognitive bias to allow for better responses to complex problems. Data and research have advanced so rapidly in the last several decades that it is difficult for even the most ambitious of police leaders to keep pace. The Twenty-one Mental Models were synthesized to create a framework for any police, public, or community leader to better understand how cognitive bias contributes to misunderstanding data and gives the reader the tools to overcome those biases to better serve their communities. The book is intended for a wide range of audiences, including law enforcement and community leaders; scholars and policy experts who specialize in policing; students of criminal justice, organizations, and management; reporters and journalists; individuals who aspire to police careers; and citizen consumers of information about policing. Anyone who is going to make decisions about their communities based on data has a responsibility to be numerate and this book Twenty-one Mental Models That Can Change Policing: A Framework For Using Data and Research For Overcoming Cognitive Bias, will help you become just that.

Policing in the US and many western nations is in an era of crisis, facing extensive calls for reformation and change. This edited book outlines the major challenges and changes needed to achieve a more stable future for the policing profession and police organizations. The chapters come from innovative police leaders and officers as well as academics with subject matter expertise, to provide insight into how reform can be done with the police. It focusses on how leaders should understand and approach their role during times of instability and uncertainty. It starts with an examination of how policing reached this state of crisis and discusses some interviews conducted with police leaders, particularly chiefs as agents of change and reform. This is followed by chapters from several veteran police leaders and personnel describing some of the factors that brought policing to this critical time of change and reform, how has policing evolved in the late 20th and early 21st centuries, and how that impacts the current environment, and some potential strategies to create meaningful change while considering unintended consequences. The following chapters from academics seek to define paths that policing can take toward needed changes that will increase legitimacy, trust, and equality of policing services. It speaks to students, academics and professionals interested in police organization and administration, police leadership, and contemporary issues in policing and criminal justice.

Crime research has grown substantially over the past decade, with a rise in evidence-informed approaches to criminal justice, statistics-driven decision-making and predictive analytics. The fuel that has driven this growth is data – and one of its most pressing challenges is the lack of research on the use and interpretation of data sources. This accessible, engaging book closes that gap for researchers, practitioners and students. International researchers and crime analysts discuss the strengths, perils and opportunities of the data sources and tools now available and their best use in informing sound public policy and criminal justice practice.

Over the past ten years, the field of evidence-based policing (EBP) has grown substantially, evolving from a novel idea at the fringes of policing to an increasingly core component of contemporary policing research and practice. Examining what makes something evidence-based and not merely evidence-informed, this book unifies the voices of police practitioners, academics, and pracademics. It provides real world examples of evidence-based police practices and how police research can be created and applied in the field. Includes contributions from leading international EBP researchers and practitioners such as Larry Sherman, University of Cambridge, Lorraine Mazerrolle, University of Queensland, Anthony Braga, Northeastern and Craig Bennell, Carelton University.

Blue Bias is a book for police candidates, seasoned officers, police supervisors, citizens who seek a truly just society, journalists who want to understand the psychology and temperament of peace officers, and people who simply want to better understand the concept of criminal justice beyond what can be learned by watching police dramas. Consider the following: Another day, another video of a fatal police shooting hits the internet. Outrage, grief, fear, charges of racism and police brutality follow...and the officer in question may or may not face indictment. But in the end, very little changes-vulnerable communities feel that they cannot trust the police, and peace officers struggle to perform their jobs justly in profoundly stressful environments.Former police officer and author of numerous books and essays on the subject of self-education, Charles D. Hayes wants to fix that. In Blue Bias, he delves deeply into the question of what can go wrong in policing, for both officers and communities, and explores ways to make it right. His solution is ultimately simple: Know thyself. But to accomplish this edict requires a genuine appreciation of the complexity of human biology, and an incisive understanding of the role our subconscious plays in forming biases, and then confirming prejudices that conflict with our own sense of morality. If you want to be a police officer or simply better understand what policing is really like, this book is an insightful attitude check. Hayes asks that you, the reader, pin an imaginary badge on your shirt, a gun on your hip and take a front row seat in his big city police academy, because as he explains, it's the only way to understand what policing is really like and why it is a much harder and potentially more rewarding and a more stimulating job than is commonly thought. Drawing on decades of research, Hayes introduces his readers to their own brains and the sentinel awareness of their limbic systems.

This practical and accessible guide shows how police forces of all sizes can successfully adopt evidence-based methods. Drawing on experiences of North American policing, it sets out ways for decision makers to reshape practices, strategies and organizational structures and overcome barriers to change.

As unrest over officer-involved shootings and deaths in custody takes center stage in conversations about policing and the criminal justice system, Guidelines for Investigating Officer-Involved Shootings, Arrest-Related Deaths, and Deaths in Custody addresses critical investigation components from an expert witness perspective, providing the insights necessary to ensure a complete investigation. Investigating a custodial death or an officer involved in a shooting presents unique and complex issues: estate, community, judicial, agency, involved officer, and public policy interests are all at stake. These types of deaths present various emerging medical, psychological, legal and liability, technical, and investigatory issues that must be addressed through a comprehensive investigation. This book is ideal for students in criminal investigation, death investigation, crime scene investigation, and special topic courses in custodial deaths and officer-involved shootings, as well as for death investigators, law enforcement officers, police administrators, and attorneys.
