The CPS worker should be brought up on charges: contributing to the delinquency of a minor. Child endangerment. Child trafficking. I'm no lawyer but that's just off the top of my head. Firing isn't enough. She'll move one county or one state over, like a cop, and get another county job. This kind of thing IS endemic in administrations, or will become so if it isn't STRONGLY discouraged. Make an example of her.
Perhaps whoever investigates will care if it's also determined that she did this to white teens, as well. Assuming the investigators even go that far, which might be presuming a hell of a lot.
