The focus of intervention in the criminal justice system is first to:

The focus of intervention in the criminal justice system primarily centers around protecting the health, safety, and welfare of the public. This is fundamental because the criminal justice system is tasked with maintaining societal order and ensuring that individuals are safe from harm. By prioritizing public safety, the system establishes a framework through which other interventions, such as rehabilitation and treatment for offenders, can be implemented effectively.

When interventions are designed with the public's well-being in mind, they can also address the underlying issues that lead to criminal behavior, including substance abuse problems. This approach allows for a more holistic view of crime and public health, emphasizing a balance between accountability for criminal acts and the need for rehabilitation.

Rehabilitation, while important, is a secondary goal that stems from the primary aim of public protection. If interventions did not first prioritize the safety of the community, any attempts at rehabilitation could be rendered ineffective or even harmful. Therefore, the focus on public health, safety, and welfare is essential as it sets the stage for more comprehensive strategies within the criminal justice system.
