The below data shows the percentage of prisoners serving time for different types of crimes: (Bureau of Justice Statistics)

Violent - 52%
Property - 21%
Drug - 20%
Other - 7%

This, along with the information in the article shows me the police, and courts are at least doing part of their job. But the really scary thing about it is: Crime, in most major cities, is still out of hand, and getting worse.
With all the people that are confined to prisons and jails, there are still far to many on the street, due to plea bargains and deals cut with prosecutors.
