Mom needs to elect trial by judge and jury, and fight the socialist deep state. Then when she is found Not Guilty, she needs to sue the school district for millions. Take their money away, destroy socialist schooling.
Mom may not have the funds/insight into the legal system to pull off a jury trial. In this case, the school system is successful in their bullying efforts.
What does this teach the kids? You, too can be a bully so long as you do it legally.
