Let me say that police do not take children out of a house without cause. They do not go door to door looking for work. They do what they are ordered to do by some agency or District Attorney.
Child Protection can order a child taken away from a home.
Medical centers can have police bring a patient back in that has been taken against medical directives.
Please bear in mind that you heard only one side of the story. I bet when the whole story is told, you might change your mind about the issue.
Had the baby died from abuse, neglect or whatever, would you fault an agency for not doing something? Did you read about the couple that did not believe in medical drs that had their second child die from lack of medical care? Would you think the CPS should have taken that child?
The problem with news media is that none of them tell the entire story but just give one side.
