re: Kid who beat teacher for taking away his Nintendo has pled guilty. Punishment?

My wife and I have been fostering children the last couple of years and after a couple of placements with teens we finally had to stop taking them in because the system makes it near impossible for them to be successful in school and because of that, tougher in the home. The two teenagers we took in had no business being in a classroom with other students but because of the rules when it comes to fostering kids in Missouri they had to be in public school. Both of the teenagers we took in would have been better served by homeschooling so not only would they get a better education, but they wouldn't have been a distraction to the rest of the school. It is sad to say, but some of these kids are so screwed up, they just can't be successful in a traditional classroom setting. I bring this up because one of the kids we took in was expelled from his school for assaulting his principal a few years back. He was a perfect kid at home with us, but literally every time he went to school, he got in trouble. We are out in the country but we have an excellent homeschooling group in our area where half the time kids are at home doing traditional learning, but the other half of the time local farmers and ranchers have classes teaching them non traditional classes. I wish the two teenagers we took in could have been home schooled, maybe they would still be in our care but unfortunately the system didn't allow it, and because of that became too much for my wife and I continue fostering them
