There are a lot of good career for the Criminal Justice field, it is depend what you like, the environment, people you will work with or on and some are about the paid as well. You can do Criminal Intelligence, police officers, investigators, corrections officers, social workers, substance abuse counselors, probation officers, security, and fraud prevention. But it will be better to understand what they do and more. I think during the course work you have taken, you should have a bunch of guest speaker, site visit, and etc. coming to you where you can ask question, learn about their profession as well as taking the opportunity for shadowing, volunteering, internship, or maybe a part-time field study. I would recommend check with you college department or adviser or course professor and see what they can assist or guide you to your interest in the field and go from there and on.
