Very true. I used to volunteer with an advocacy group that helped parents whose kids were wrongly taken by CPS and what I saw of the system scared the crap out of me. It does some good work but the sheer stupidity of some of the employees, the arbitrary powers and lack of due process was the stuff of nightmares.
I read that last one and I'm not sure the "free range parenting" bill would even cover that. That was a case of, baby had a bruise and a doctor arbitrarily decided it was a willful injury by the parents. A process as aribtrary and random as that seems pretty broken and after that the foster process failed catastrophically. But I doubt "free range parenting" shuts down the entire process of removing kids from environments that are detected (rightly or wrongly) as directly physically abusive.
It is frightening. And it varies significantly by state.
For example Utah (where I foster) has 2.8 per 1,000 children in foster care, while neighboring Nevada has 6.7 per 1,000. New York has 5.0. California has 6.2. [1]
The ever-conservative Utah legislature puts a very high priority of children living with their legal parents. As long as there's no imminent health risk (abuse, hard drug use, severe neglect), parents virtually always keep custody.
I really wish it were like that in more places.
Traumatic situations for children should not be taken likely. But being forcibly removed into state custody is also a very traumatic event. You've got to be confident that the latter is the lesser evil.
