He didn't say he kicked his butt, he said he put him on the ground after the kid tried to punch him. Kids will be kids, but destroying property or causing harm to a person or an animal crosses the kid being a kid/kid being a delinquent line, and there are consequenses. I would have put the punk down and held him until police got there to take him away. Children might be different where you are in Kansas, but I promise you that plenty of kids here act more like slow thinking, adult criminals than kids. It's a shame, but it's a fact.
