Here's a few examples that's happened to me personally

(1) I didn't personally appear at bus stop, thinking my kid would be able to just walk the short distance from the stop to our house. Nope, school did not let kid off bus, given a timer to show up at the transportation office before child services will be called.

(2) Let my kid walk on our own property, someone drives up and starts interrogating them why they are "alone." Fortunately I was actually watching from further away and I managed to diffuse the situation before they alerted the authorities.

(3) Took my kid to the park so they could have a nice time outside in public. Whoops, looks like my child is a difference race than me. That means I am a kidnapper. Karen (from bodycam, a passing yuppie looking cyclist) calls police, who arrive and scare the shit out of me and my kid and detain us for about an hour. Not released until a woman's voice comes on the phone (they literally did not check, just any female voice) says the man can let his child play at the park. They also contacted child services of both the city of the park, and my hometown -- fortunately even though the city of the park looked like they were ready to fuck with me my hometown CPS did tell them to kick rocks and since I left town there was nothing further they could do.
