Drugs, bullying, binge-drinking, truancy, vandalism, shoplifting and assault - these are the first teenage steps that can lead to a life of crime. Teens on Trial is a new reality experiment that aims to halt this depressing decline at the first hurdle - using the effective method of peer pressure. The Teen Court is run just like a real court but with teenagers taking all the key roles - lawyers, clerks, ushers and jurors. The key difference between this and a criminal court is that Teen Court defendants have already admitted their guilt. The task of the teenage jurors is to find a punishment to fit the crime. Could this scheme help curb Britain's growing yob culture?
