Master Sgt. Jeffrey Bury, 11th Security Support Squadron NCO in charge of training, inspects a window as part of a vulnerability assessment Aug. 20, 2015, at Imagine Andrews Public Charter School at Joint Base Andrews, Md. If a window opens, it could serve as both an access point for an active shooter or an escape route away from one. (U.S. Air Force photo by Senior Airman Preston Webb/RELEASED)
