(AP) — Gov. Bruce Rauner wants to replace guards in watchtowers with closed-circuit cameras at nearly two dozen lower-security Illinois prisons, an effort to cut expenses for a cash-strapped state that has gone two years without a budget. The administration is projecting $4 million in annual savings through reduced overtime-pay and "more efficient management strategies," Rauner spokeswoman Eleni Demertzis told The Associated Press. The Republican governor's office didn't provide specifics on the change, which would affect the state's 23 minimum- and medium-security facilities. Officials had discussed with the union the idea of using high-tech cameras to enhance security, but a union leader said he's wary of removing people from the lookout points. A high-profile escape in 2014 from a prison in Ionia, Michigan, sparked a debate about whether replacing tower guards with cameras hampers safety. Rauner, a private equity investor when he took office in 2015, campaigned on curbing union power in a solidly Democratic state and has clashed repeatedly with organized labor.
