For more information on the rate of incarceration in the US:

While the state of Illinois is unable to pay its bills and Cook County is consistently in a budget crisis our legislature continues to pass laws that require non violent offenders to spend time in custody.  An all too often occurrence exists where a defendant's license is revoked for a DUI, he/she is caught driving for the fourth time after the revocation and he/she is required by the statute to spend 180 days in the Illinois Department of Corrections.  Bear in mind that many of these defendants have no other criminal background, no history of violent crimes, and many times, have only had one DUI (but poor legal representation on the DUI case).

If Illinois wants to save money, they should find a way to stop locking people up for something as silly as driving a car.  I have more than a few clients who would be happy to help the State with their bills by paying a fine rather than costing the State money by being locked up.
