First one, not treated as a crime. But there is a record, so that sucks.
Second one, leaving your 9 year old at a park all day while you are not there. I can see why that is a problem.
The third one is maybe where the is controversy. It would be nice if a 6 year old could play on the street by themselves. I think there is some discretion here and it depends what your street and suburb is like to some extent.
The last one is tragic and totally unfair to the family. Looks like another nail in the coffin for people without a lot of money in the US (who can't call a babysitter on short notice) and who use common sense. Then they get a criminal record, lose their jobs etc, can't get a new one etc. F'd.
