Photography and? Criminal Justice degree?

I am studying criminal justice. I should be graduating in July of next year! Yay! However, not necessarily work as an officer or P.O.: far from it. I also would like to obtain a degree in photography but work in the law enforcement field. Could anyone provide me with information that would make this type of job work? I think I have found my passion for life and I would like to grant it for myself. Thank you!
