It makes you wonder what the appropriate level of cynicism is though. I assume you mean N=1 in an order of magnitude sense. But one person saw these kids and phoned it in. A cop returns the kids home with a warning. 3 more cops show up the next day and arrests the man only (but both parents should be negligent should they not???) and then some social workers appear.
How many people heard about this and decided to waste time and resources either wilfully or unwittingly, and is that a reflection of the state law enforcement and social services?
Many (most?) states have mandatory reporting laws. People in certain positions (doctors, teachers, social workers, etc.) are required to report even an inkling of suspected abuse. I'm sure multiple people in the chain knew this was nonsense but none was willing to put their own career and/or freedom on the line for it.
