U.S. President Barack Obama and Michelle Obama attend a memorial service at the Marine Barracks Sept. 22, 2013 in Washington, D.C., for the victims of the Sept. 16, 2013 shooting at the Washington Navy Yard that took 12 lives. On the day of the shooting, Foreign Policy's Yochi Dreazen reported on how the tragedy highlighted the military's many security flaws. "Visitors to the Pentagon walk past guards armed with assault rifles and then pass through an outside building equipped with state-of-the-art metal detectors," he wrote. "[But] at military posts like the sprawling Marine base in Quantico, Virginia, for instance, anyone with one of the Common Access Cards issued to troops, civilian Defense Department employees, and government contractors can enter the facility without being patted down or made to go through a metal detector."
