It's called restorative justice and it applies to kids of color. They are not punished anymore if their skin color is dark and they know it so they do whatever they want including acts of violence. This is happening in big city schools all over, look it up.
Too many parents living on welfare, never having to face responsibility or consequences, so they have no way to teach it to their children.
The teacher is the victim of an angry and violent teenager, and the teenager is a victim of her culture. I bet that the day she entered school, she was already behind those who were encouraged and helped at home to learn and read before their first school day.
She most likely argued with the teacher over a failing grade, blamed it on the teacher and "systemic racism", and lashed out. Now she has a felony charge on top of dismal grades. Additionally, she's fat and ugly. Having black skin is the least of the problems for her future life. She will most likely use "systemic racism" as an excuse for other failure or disappointments. But the reality is that nobody likes dumb, fat, and nasty people even if their skin were gold-plated.
We desperately need intensive-care schools for kids of any color who are significantly behind the normal level of knowledge and social development. The graduation standards and behavioral standards should be close if not equal to regular schools but additional effort and tutoring should be provided to close the gaps. This will cost money but any student that can be saved that way is not going to cost society via destructive behavior, a life on welfare, or both.
During my high school days in Germany we had four tracks. One with academic focus (
Gymnasium), one with basic, practical focus (
Hauptschule), one in between (
Realschule), and one for the mentally/developmentally challenged (
Sonderschule). I think that does the different abilities and developmental progress (early vs late bloomer) of children more justice than the 'everybody through the same mill' approach we have here.
