Basic Concepts in Criminology is an introduction to criminology. It is intended to serve as resource material for prospective students of criminology and particularly for law enforcement officers in training and in the field. Criminology as a social science discipline is structured from a combination of concepts of sociology, psychology, and law-all relevant subjects to the law enforcement profession. Remarkably, criminology is not very popular as a stand-alone subject among disciplines of choice for undergraduate students or even for those going in for graduate studies. Instead, what we notice in most universities' curricula are related disciplines, like criminal justice, criminal investigation, crime scene investigation, forensic, law enforcement, and so forth. Material contained in this book will be particularly useful to law enforcement officers; the Police, Corrections, and Security officers. In this book, I have attempted to approach and make this subject much easier and interesting to prospective students of Criminology in general and to law enforcement officers in particular, to whom knowledge of this subject is an important professional asset. I hope it will stir and arouse their interest and that of prospective students of Criminology in general.
