My son got suspended the second week of school after he got into an argument that turned into him fighting while playing soccer at recess.   
My son was playing and some kids were being rude to him and changing the rules of the game. This turned into my son getting upset. He still struggles to regulate his emotions especially on days he’s tired (which he was that day plus his older sister just has surgery two days prior.). He started yelling bad words and violent things. The at risk coordinator noticed and told him to go inside. But I’ve always told him to walk his anger out because it works for him. Well he started to do a large circle around the playground and the coordinator was following him. Which riles him up more. He then goes after one of the kids he was fighting with and hit him. Then tackled the other one. The coordinator took that opportunity to restrain my son and get him inside. My son yelled at him and the office staff for a little while after. By the time I got there he was calm. Truthfully I was shocked this happened since he has come so far and didn’t have any incidents the entire summer and is great with his actual soccer team.   
We have a meeting today to go over everything and they are doing a risk assessment tomorrow without us. I emailed the principal requesting the video footage and the written physical restraint report so hopefully with get that later.   
I also wrote up a few documents and I’m not sure if I’m going to far or not with the papers

Am I going to far after my 10yr old got suspended?
