I am struck by the fact that arguments for or against within this thread are only about perceived safety (something hard to know at a distance) and not the substance of the law involved. Does Virginia actually have laws prohibiting unsupervised 5 year olds? If so what is the minimum age at which children are allowed outside unsupervised? Does it also apply to leaving children at home unsupervised? The charge of “contributing to the delinquency of a minor” would suggest the minor’s behavior had to be illegal, which does not appear to have been discussed.

FWIW - Virginia has a free range kid law. And does not have a minimum age for supervision.

They charged the mom with delinquency of a minor to get around this. Usually reserved for teenagers that commit crimes.

We don't really know all the facts, and we only get one side of the story here. So we all need to keep that in mind too.
