If we want to use the worst examples as the example to measure schooling by then I think the worst examples of home schooling should really be emphasized here. Wasn’t there a case recently where a white mother of adopted black children took and homeschooled her children after teachers tried to report possible abuse- and then the mother later went and killed her children and then herself? I believe that was the background to a popular image of a black child hugging a cop and looking into the camera with tears in his(the child’s) eyes.
