The bill lawmakers sent to Rauner went too far. It would have required gun shop employees to pass background checks and take mandatory state training. Shops would have to install surveillance equipment and alarms. Owners would need a county sheriff’s approval to get a license and would have to open their records to law enforcement, to name just a few of the rules. The designated state oversight agency — the Department of Financial and Professional Regulation — opposed the bill because the agency doesn’t have the resources to enforce it.
