I think you're confusing the role of CPS with the police. It's the police who investigate crimes and provide evidence to the courts, who will in turn mete out any punishments. CPS's job is to protect the kids. AFAIK they aren't involved in any kind of punishment. Any measures they take are limited in scope to the best interests of the children. Now, they're indifferent to the impact on the parents, so some of the measures to protect the kids can feel like punishment to the parents, but that's not their concern. I keep feel like people aren't able to draw the line here between what CPS did and what the cops did. Absent more details on the story (and we always have to keep in mind that we're getting the version of the story that is most charitable to the mom), it sure seems like the cops really messed up here. Once the cops arrested her, that's when CPS got involved, and the consequences from CPS's involvement were pretty much inevitable, and frankly the least of the hardships placed on that family.
