Elements of Crime Patterns is the first detailed compendium of the specific elements and variables of crime patterns. It articulates tacit and implicit knowledge about what crime patterns consist of and contains a wealth of information illustrating what could be in a crime pattern. It details the offender and victim, location and time, weapons, tools, equipment, travel, communication, and methods used to commit crimes. The behaviors in 27 crime categories are succinctly but specifically examined, from robbery, burglary, and cybercrime to sexual assault, terrorism, and drug trafficking. This book serves as an “anatomy book” of crimes and as a type of diagnostic manual. To diagnose crime patterns more accurately, it is wise to obtain a thorough grasp of their possible parts and what these parts might look like. By recognizing crime patterns sooner, we increase the likelihood of preventing crimes, apprehending criminals, understanding problems, and developing more effective crime reduction tactics and policies. So much basic information in one place allows those who work in policing to formulate better questions when working in traditional ways and when interacting with artificial intelligence systems. Novices to the subject will gain foundational knowledge. Experienced police officers, investigators, and analysts will utilize the book as a comprehensive reference tool. Criminal justice students, teachers, and researchers will learn the ins and outs of crime patterns.
