>>4690152American law has the concept of torts. Let's say you set fire to my shed or something. You'd be tried in the criminal courts for the crime of arson. And then I can sue you in the civil courts for the damages you did. You have to do separate courts since they have differing requirements. Criminal requiring "beyond a reasonable doubt" and civil "the preponderance of the evidence."
That being said, no jury will actually see him go to prison. These kind of child avenging cases rarely see the guy get sent away.
