Introduction

This chapter introduces the central purpose of the book to document and organize the elements and variables that constitute crime patterns. While no single volume can capture every detail, this work offers a comprehensive starting point designed to establish a shared vocabulary for law enforcement practitioners, analysts, researchers, and educators. It positions itself as a descriptive rather than prescriptive resource, intended to support recognition and identification of crime patterns in practice rather than propose a new theoretical framework. The chapter defines crime patterns with reference to established sources, including the College of Policing and the International Association of Crime Analysts, and illustrates these definitions through practical examples. It distinguishes between recognizing and identifying patterns, highlighting the role of repeat offenders and behavioral consistencies in shaping investigative outcomes. Finally, the chapter outlines the book’s structure, audience, and international applicability, emphasizing its utility as a practical reference and cognitive tool for improving situational awareness and advancing crime pattern analysis across professional and academic contexts.
