Um, what exactly was the kid arrested for again? He viciously attacked an adult. Case closed.
If you are going to mainstream your child, then you mainstream your child. You shelter and coddle them in school with their IEP's and then they graduate to a world they can't function in because the bar has been adjusted for them the whole time.
This kid was disruptive and detrimental to the class, refused discipline, and attacked an adult. How do you think that would be dealt with "in the real world"?
Thank you and well said.
