Law enforcement personnel train at Hanscom
                Local, state and federal law enforcement personnel participate in a simulated active shooter event at Hanscom Air Force Base, Mass., June 26. The training provided more than 750 law enforcement personnel the opportunity to hone their tactics and techniques in the event they are faced with a real-world incident.
