The Illinois Department of Corrections say revised legislation stiffening penalties for gun crimes would still cost hundreds of millions of dollars and add inmates to the crowded correctional system.
The agency says the latest version of the gun bill would add nearly 2,500 inmates to the state’s prison system and cost another $549 million over 10 years. That covers operating and construction costs.
The amended bill is backed by Chicago Mayor Rahm Emanuel and makes illegal gun-holders serve more prison time. The original measure required a three-year mandatory sentence for first-time offenders.
