While things like armed officers in every school and bullet-resistant glass remain on the wish list, upgrades are on the way in areas school officials hope will make Warren County campuses safer.Bids are being accepted for the installation of magnetic locks throughout the school system. The installation will be joined by security cameras.“We want all this done by the coming school year,” said Director of Schools Bobby Cox of the large-scale security upgrades.The changes come on the heels of the Newtown, Conn., tragedy in which 26 students and school officials were shot to death by a deranged man late last year. That incident has led for a movement to put armed officers in each of the county’s schools.
