Hi, I'm desperately looking for some advise about my son's situation. He hacked into the school computer system and changed a desktop picture. In return, the school reported him to the police. After 3 months, the police decided to give him a conditional caution. Both the police, YOT and the firm which provided a duty solicitor during the police interview are nagging me to sign it. I am hesitant though because this will be on my son's record forever and he didn't do any damage to the school. His intention was to let them know that the system was insecure and easily accessible. What is going to happen if he doesn't sign it?
