Atlanta school officials are vowing to re-inspect every metal detector in the school system, but the school board chairman is raising questions about how metal detectors are used -- and how often.

Atlanta Public School officials acknowledged Friday that metal detectors weren't working at Price Middle School when a 14-year-old student was shot and wounded last week. The shooting took place on campus, but outside the building in an area that's publicly accessible.

On Monday, the school system's superintendent, board members and security chief all said the shooting exposed gaps in school security and a still-unknown number of broken metal detectors.

School Board Chairman Rueben McDaniel said he's worried the district might not have set policies for how or how often metal detectors are used.
