That's what boggles my mind the most. Every time we hear about CPS they're overworked and have to deal with horrors I don't even want to imagine. But how do they have time to waste voluntarily ruining peoples' lives?
I can speak from experience here, I have dealt with CPS. When I was notified they would be visiting our house, I did some research. I read the horror stories, and I learned a key detail: CPS is not a policing agency. The threats of taking your children from you and throwing you in jail are idle: only police and judges can do that. When you deal with CPS, only let them in your house if they agree to be recorded. If they refuse, or their supervisor objects, don't let them in. Unless they have a warrant, you are under NO obligation to deal with them. (Bear in mind, though, the courts will probably side with CPS)
But I digress. My experience with the social worker was that she was just as nervous in dealing with me as I was with her, but she was genuinely interested in understanding and offering assistance. She asked a few questions, held a follow up visit, and that was the end of it.
I'm actually more shocked that there are prosecutors and even judges that go along with this BS. I can believe one insane activist CPS worker here and there, but an entire chain of people to back them up??
