FILE - In this June 2, 2019, file photo, a volunteer prepares to place crosses for victims of a mass shooting at a municipal building in Virginia Beach, Va., at a nearby makeshift memorial. Police responding to the deadly mass shooting were unable to confront the gunman at one point because they didn’t have the key cards needed to open doors on the second floor. Whether the delay contributed to the death toll is unclear, but the episode illustrated how door-lock technology that is supposed to protect people can hamper police and rescue workers in an emergency.
