Need help with a tutoring question for family law

John drove his nine-year-old son, Johnny, and the family four wheeler to Larry's farm. Neither John nor Johnny had permission from Larry to be on his farm. John put Johnny on the four wheeler. John said to Johnny, \"Have fun. | will be back to pick you up in a couple of hours.\" Johnny destroyed Larry's ripening wheat crop. Will the court hold John civilly liable? Criminally liable? Why
