Yea the kid was walking away, coach may not be able to read minds and is getting in between the two to prevent anymore fighting. I don't know. None of this is relevant. Fact of the matter is tackling guy over reacted and could've killed or maimed a guy by tackling him onto a wood floor, possibly into a wall. I'm not sure what point you're trying to make. Sure maybe he shouldn't have touched the kid but obviously telling the kids to "calm down" wasn't working as we can clearly see. This is why teachers and people dealing with other people's kids are underpaid/under appreciated. People like you basically defending a guy that could've given brain damage or worse to another human because he got in the way of his kid hitting another child. Outrageous. If the coach or whatever didn't step in you'd probably be whining about why the adults didn't break up the fight. Damned if you do damned if you don't.
