The only one who really had a problem with this was the person in the article who called the cops.What the heck? Didn't read 8 pages, but don't tell me people here have a problem with a 9 year old watching a 6 year old while outside playing.
I've only been alive for 3 decades, and even I remember a time when this was normal.
In a small city, before cellphones even. Just be home by dinner.
Physical abuse is pretty cut and dry and easy to identify. Negligence is a totally subjective concept. Quit trying to Nerf the world.
At least these kids were outside. I'd say parents who let their kids sit in front of screens for hours a day are far more negligent.
