Book excerpt: This book presents a powerful and thorough investigation into police deviance and sexual misconduct in the US. Drawing on news reports, official government press releases and academic research sources, Barker examines a wide array of cases including sexual harassment, sexual abuse, child molestation and police killings, including those of prisoners behind bars. Substantiated with additional cases from the UK, Russia and beyond, analysis is also conducted of the experiences of the victims of those crimes. Aggressors in Blue argues that this misconduct has its roots in the nature of the law enforcement occupation, and outlines the typical conditions which enables police sexual abuse to take place. This is a bold new investigation which speaks to students and academics in criminal justice, criminology and social justice in particular, as well as to scholars, social justice advocates, law enforcement professionals, policy-makers and academics in other related disciplines.
