I live in the Orange County area of Southern California, and to be honest, I have not been through any criminal justice programs of any community colleges. However, you can try the Administration of Justice Program at Irvine Valley College or Criminal Justice program at either Orange Coast or Goldenwest college. Be wary that some police agencies like Irvine PD require that you have a Bachelors Degree before applying, so I also agree that it is better to go to a 4-year school. Hope that helps and good luck!
