Law school after a bs in criminal justice?

i'm a little confused. I'm currently attending ITT Tech for a BS in Criminal Justice. If i wish to pursue to a Master's would I go to UOP or Humphrey's... What's the next step? that's my question... I would like to work in a field of counseling youth. For instance at a juvenile facility. I don't necessarily want to be a lawyer, but i just don't know where to go from here to obtain my goal. Would i have to change my studies into something with counseling or mentoring?
