Metal Detectors Aren't a Magical Safety Solution
There are no two ways about it: school shootings are terrifying. Students, parents, teachers, and communities are horrified by the thought of someone violating what we’ve always thought of as one of our safest spaces by firing a weapon with the intent to kill.
Criminologists point to statistics confirming that the number of such shootings really isn’t on the rise, noting that schools continue to be among the safest places for young people. Still, given the explosion of media and social media coverage, the average person can’t be faulted for thinking America faces some kind of violent new epidemic.
After this spring’s highly publicized incidents in Parkland, Florida and Santa Fe, Texas, and another in Noblesville, Indiana -- not far from our company’s offices -- there’s been an outcry calling for “hardening” school buildings to thwart potential shooters. In particular, many well-meaning people have insisted that the best solution is to place metal detectors at the doors of all schools. Indiana’s Governor recently made hand-held metal detectors available to all of the state’s schools at no cost to the districts.
Metal detectors have their place in security, but they’re not the foolproof or magical solution many advocates believe them to be. First, metal detectors are personnel-intensive devices. To provide adequate protection, they have to be staffed any time anyone enters the building. That not only includes the times when large groups of students are arriving for school, but throughout the day, and for high schools, into the evening and weekends.
If the swim team arrives for practice at 5:30 a.m., somebody has to be there to scan the members and their gym bags. If practice for the spring musical runs all evening, someone has to be there to scan all the participants. The same goes for sporting events. If there’s any gap in scanning, it creates an opportunity for someone to smuggle a weapon into the building and place it in a locker or other location for later access.
Not only do trained people have to be on hand to perform the scans, there has to be an established process when the detector identifies a suspicious person or object. Who will be responsible for frisking students or searching their bags? Will that interfere with the flow of students coming into the school?
Nor are all weapons made of metal. Even with every door protected by a metal detector, students could bring weapons made of wood, plastic, or other materials without detection. That creates a false sense of security.
Finally, if metal detectors placed at building entrances create a crowd of students who are waiting outside to get into the building to be scanned, that crowd becomes what’s known as a “soft” target. It would be easy for someone on the school grounds or in a nearby vehicle to open fire into that crowd with a weapon and inflict mass casualties. That individual wouldn’t even need a gun -- choosing instead to mimic the actions of terrorists in Europe and elsewhere who have simply driven vehicles into crowds.
It isn’t that metal detectors are inherently bad. But they’re not a panacea that will eliminate school shootings. Parents and others want a simple, easy-to-implement strategy to secure their children’s schools, and such an option just doesn’t exist. If it did, law enforcement officials would be leading the movement to use it. The fact that you don’t see police departments and law enforcement experts pushing for simple solutions like metal detectors is that they know better.
Effective school security encompasses several components, many of which can’t be purchased from suppliers. One of the most important is awareness of the hazards and having systems for alerting the authorities to potential threats. In nearly every major school shooting, we’ve later learned that the shooter had made threats or shared plans in advance, yet that information was never passed along to those responsible for security. Schools need a means through which people can safely report concerns about individuals.
In addition, it’s important to address visitor access. In the Parkland incident, the shooter was a former student who had no reason to be in the school, yet he easily gained access to commit his violent act. Would the outcome have been different if he had to obtain access to the building through the office and obtain a pass? Any answer is just speculation, but it’s worth thinking about.
Students and teachers need to be protected, but demanding simple solutions isn’t going to provide safety for everyone. The real answer is replacing rhetoric and social media chatter with thoughtful planning by professionals.
