All we can provide to you is the data. We wouldn't be able to provide you with the explanation underlying the data. What the graph is showing you is the trend in non-violent and violent cases that are sentenced to custody, over time.
We can look at that percentage and we can see that since 2003-04, with the implementation of the Youth Criminal Justice Act, the number of violent cases sentenced to custody has decreased. In 2003-04, it was that 21% of violent cases were in custody. We are now, in 2008-09, sitting at 17%.
