The criminal justice industry deals with various aspects of processing criminals through the court system and monitoring their activities after they have served their court sentence, whether jail time or probation. Law enforcement entails policing and enforcing laws; many of the careers in the field entail investigating suspicious activities, gathering evidence and facts about crimes, and studying and analyzing criminal behavior and crime statistics.
