Dealing with juvenile delinquents

The recent detention of 17-year-old Li Tianyi, son of famous singer Li Shuangjiang, along with four other youths for suspected gang rape has topped national and local news in recent days. It's not surprising to see that most of the people are more interested in the wrongdoings of the boy and his parents than in the root causes of juvenile crime and how to prevent juvenile delinquents from committing more offences.

A key issue that emerges from the incident and the following developments is why was Li Tianyi not put through a correctional juvenile facility after he (and another youth) was arrested for beating up a couple about two years ago.
