Criminal justice can be defined as the study/application of principles and laws when analyzing criminal activity. Graduates of criminal justice programs include police officers, judiciaries, as well as defense and prosecution attorneys. Some individuals spend their time advocating for reform in the current criminal justice system, such as judges from county courts or members of Supreme Courts. Criminal Justice is also known as the process involved with some type of criminal behavior such as discovering and processing evidence, arresting an accused individual, preparing defense, participating in trials, deciding on judgment when a crime is proven, or carrying out the judgment itself.
