Doctors and teachers handle that, since they have regular contract with children. At least in my state they're required by law to report suspected child abuse.
As a side note, these laws are doing damage to organizations looking for volunteers that I don't think we have fully grasped yet.
People are willing to put a couple of weekends into making a middle school or high school competition happen. They're a lot less willing to do it if they have to go to an FBI station to get fingerprinted or produce a state and federal background check first. And I'm not talking about people with something to hide; I'm talking about people with a completely clean background who just don't want to be bothered.
NZ OP here. Few weeks ago there was a morning checkpoint to inspect everyone's child car seat installation.
Few years back got chased by a cop and ticketed (and scolded) for not restraining kiddo (small town and my clever 2yo somehow learned how to unbuckle themselves (even that houdini clip didn't help)). Warned I could get prosecuted for child neglect if I continue. I suspect the daycare has tipped him off.
Making slippery slope arguments like this is not discussing in good faith. I was providing the context of someone who lives in that geo-political area.
And check that every single one of your federal papers are present and punctual. We'd hate to have someone that's unbecoming to share a full disclosure of themselves to officers on the road.
