Democratic Gov. Andy Beshear of Kentucky signed into law a bill that requires school resource officers to carry a firearm.

"As a parent and as your governor, I want Kentuckians to know that I see the safety of our families and children as my top responsibility,” Gov. Beshear said. “I am taking the steps to protect our children in schools – to ensure that the next time an armed individual enters a Kentucky school, there is a sworn law enforcement officer there, armed and well-trained. We’re going to give them the tools they need to stop the worst of the worst.”
