A recent scare at Walter Reed National Military Medical Center in Bethesda, Md., was an active shooter drill gone wrong, according to an article on the Campus Safety magazine.
There was a drill planned for that day and an alert was accidentally triggered that did not specify it was a test, causing workers and patients to seek shelter.
The navy called the incident an “improper use” of the warning system.
“While preparing for an upcoming drill, the notification system inadvertently enacted without containing the words ‘exercise’ or ‘drill,’” the Navy said in a statement.
The mix-up led to a large police response, including SWAT teams who arrived on the scene.
