Other jobs in the criminal justice field involve becoming a prosecutor or a public defender.
Both the prosecutor and the public defender require a law degree on top of the preliminary Bachelors. For law school it really does not matter what your major is, but a degree in criminal justice would be helpful.
In addition, you have to pass the bar exam in order to receive your license to practice law in your state. Most lawyers that start out in the prosecutor’s office work as an Assistant DA or district attorney.
Here you are given a geographic territory as well as possible specialization of cases. For example, if you are an Assistant DA of Queens, you may handle cases regarding the Flushing section of Queens, while another Assistant DA handles the Ozone Park area.
There are multiple Assistant DA’s. To get to the next step you have to run for office, because the prosecutor or District Attorney is elected by the people he or she serves.
A public defender is hired by the public defender’s office and is assigned a caseload in which he or she has to take on. This is defending the indigent defendants that could not afford their own attorney.
