The social worker looks exactly like the type that would be attracted to the family destroying industry. Bitter, ugly, desires powers to abuse, willing to lie and plant evidence, etc.

And the dad and daughter look exactly like the type of family that would be accused by such people because "it just doesn't feel right" when they see a father and daughter together.

Hollywood would have a difficult time finding actors as well suited to play these parts. Unfortunately, the world is filled with evil people like this social worker, and I would not be surprised if another attacked this family. I can only hope this experience made them stronger.

And yes, the biggest crime is that the social worker was not put in prison, and did not have to pay a criminal price for her criminal actions. I suppose the justification for this is that it might discourage other social workers from lying and convicting people without evidence when their instincts could be right.
