Book excerpt: The encyclopedia of crime & justice not only discusses many different kinds of crime--from perjury to terrorism--but also looks at law enforcement, legal procedures and penalties and the social causes and wide-ranging impact of crimes on society. The articles reflect issues dominating the news and entertainment media--topics that are frequently discussed or assigned in both high school and college curricula. What is perjury? How do copyright laws pertain to the Internet? Can a juvenile be tried as an adult for murder? In 250 A-Z entries, these interdisciplinary articles deal with the sociology, psychology, history and economics of crime.
