CJ2302

CJ2302, often titled "Introduction to Criminal Justice," provides an overview of the criminal justice system, including its components: law enforcement, the legal system, and corrections. The course explores the history, structure, and functions of these agencies, along with key concepts such as crime, justice, and public policy. Students examine the roles of various stakeholders, including police officers, lawyers, judges, and correctional personnel, as well as the impact of social, political, and economic factors on crime and justice.
Additionally, the course typically covers current issues in criminal justice, such as crime trends, juvenile justice, and the implications of technology in policing. By the end, students gain a foundational understanding of how the criminal justice system operates, the challenges it faces, and the principles underlying criminal law and justice. Overall, CJ2302 prepares students for further study in criminal justice or related fields.
