This child wasn't home schooled but was no schooled. There is a big difference. The parents were caught too. How?
In the first case the child ended up in a hospital ER - in the second case through the child being arrested. I agree that the parents were NOT providing appropriate schooling but they promoted themselves as home schoolers when they removed their children from the public school system.
The term "home school" covers many different interpretations depending on who you are speaking with. I have many friends who are amazing, incredible homeschoolers - but the practice of "home schooling" varies a great deal from one family to another.
I have known several social workers who work for Child Protective Services and a frequent threat by parents who are being investigated for abuse is that they will pull their children out of school to avoid future reports.
