Introduction to Criminology: Why Do They Do It? offers a contemporary and integrated discussion of key criminological theories to help students understand crime in the 21st century. Focusing on why offenders commit crimes, authors Pamela J. Schram and Stephen G. Tibbetts apply established theories to real-life examples to explain criminal behavior. Coverage of violent and property crimes is included throughout theory chapters so that students can clearly understand the application of theory to criminal behavior. The Third Edition includes new and expanded coverage of timely topics, such as victimization, measuring crime, multicide, gun control, and hate crimes. This title is accompanied by a complete teaching and learning package.
