Sorta related. A friend has worked for CPS since the 90s. She told me that CPS (in California) has the right to enter a home without a warrant or any real judicial oversight. All they need is evidence there's child abuse going on at the home. No guidance on what qualifies as "evidence".

Well, if that isn't bad enough, it gets worse. The local police department knows this, and they use it to get around pesky search warrants. Basically, the local PD calls in a fake tip to CPS that there's child abuse going on inside a house they wanna search. CPS, in turn, calls the local PD for assistance to conduct a child welfare check inside the house. Once the PD is inside the house, they can pretty much search however they want - no warrant, and all the paperwork and accountability belongs to CPS. CPS is fully aware of what's going on; the local PD bullies them into continuing this situation, basically threatening to stop assisting them on all child welfare checks if they say anything. My friend told me it's easy to spot when this is happening because a half-dozen cops, dressed in SWAT gear, will show up to do a child welfare check, where it normally takes one rookie cop. She said she's participated in situations like this when there wasn't even any children in the house.
