Only read the first page but just wanted to say that my youngest DD has been a lot taller than average since a young age. She has a sister who is 5 years older than her, making her 18 when she was 12. With the older sister and with all these bl**dy vloggers demonstrating make up techniques/latest fashions, she could definitely have been mistaken as 16+ at 12.
The difference is that she wouldn't have been allowed on the town, let alone dressed like that. At 14, her older sister's uni friends thought she was 18 and that was during the day, in casual clothes and normal make up.
Unless you believe that the taxi driver, police, the judge were all colluding to protect this young man then I think commonsense has prevailed. This young man, has to live with this mistake for the rest of his life.
You'd be much better channelling that rage at a society that thinks it's acceptable for a 12 year old to be allowed out on the town like this.
