Final answer:
The boundaries of criminal justice agencies have changed over time, adapting to new challenges and emerging issues. Examples of changing boundaries include the establishment of the Department of Homeland Security after the September 11 attacks and the recognition of the importance of mental health in the criminal justice system.
Step-by-step explanation:
The boundaries of criminal justice agencies have changed over time. Historically, criminal justice agencies consisted of the police, courts, and corrections system. However, as society has evolved, new agencies and departments have been created to address emerging issues. For example, with the rise of cybercrime, specialized units and agencies focused on digital forensics and cybersecurity have been developed. One example of changing boundaries is the establishment of the Department of Homeland Security in response to the September 11 terrorist attacks. This new agency brought together various existing agencies and created new ones to enhance national security and combat terrorism. Another example is the increasing recognition of the importance of mental health in the criminal justice system. As a result, specialized mental health courts and diversion programs have been established to provide treatment rather than incarceration for individuals with mental health issues who come into contact with the criminal justice system.
