Well, you just moved the goalposts from "what prompts a visit", past "what gets your kids taken away", all the way to "what gets your kids taken away on a whim".
I agree that CPS is extraordinarily unlikely to take your kids away "on a whim". And yet, that doesn't mean that innocent folks have nothing to fear from a CPS visit.
The first article clearly shows that CPS will visit for any report at all, no matter how bogus or bizarre. There are controls in place to thwart repeated harassment, but for a first report, they will definitely investigate because they are legally obligated to do so.
And since the original issue was whether you might get a visit for putting your kid in a cardboard box, the answer is plainly "yes".
The follow-on question is whether that visit, investigating a stupid, bogus report, might get your kids taken away. That is going to depend on the judgment of the CPS investigator. And the second article illustrates that those judgements are not always going to be evenhanded.
> It does not matter how ridiculous or false a claim may be. When an investigator receives the referral, they are legally obligated to investigate.
It only takes a judgmental busybody to get a visit from CPS. Then you better pray CPS doesn't find fault with you. And it helps if you're white:
