Criminology is the science that makes it possible to investigate, analyze, make conclusions, and, finally, prevent crime. A crime is the constituent part of human existence. The crimes, more terrible or less abusive are well-known since the creation of the world due to the Bibles interpretation of existence. And since that time on humanity is coming closer to the problem of crime; its roots, its premises, its components, and the criminals. Criminology’s subject of inquiry is a crime, but being interdisciplinary study criminology affects many other sciences, most commonly sociology but recently more often criminal justice, psychology, political science, the natural sciences, and economics come into the view of criminology. Relatively, criminality and crime scientific study is of last few decades of development. The book by Larry Siegel turns to the basics of classic criminology and investigates the problem up to the modern society achievements in up-to-date criminology.
