“More than just machines with an uninvolved attendant standing in front of it, we need principals and parents and teachers and mentors who are engaged with the students all the time so when they have issues about safety, or isolation, we know about them,” says Teny Oded Gross, executive director at Institute for the Study & Practice of Nonviolence in Providence, R.I.
In news reports since the Gardena High School shooting, friends of the 17-year-old who carried the gun to school said he carried the gun for protection because of past run-ins with other students, but not with the intent of hurting anyone.
“Circumstances are changing for students all the time,” says Mr. Gross. “A gang member may be just getting out of prison and setting up new crews, and a perfectly nice kid feels vulnerable because of it."
"Metal detectors are an OK supplement if you have the money, but what is more important is adults on the ground knowing all the time what happened at the rec center and last night’s ball game," he adds. "Communication is the key. There are no quick fixes.”
Moreover, the money for metal detectors and surveillance cameras might come at the expense of educational programs. “Considering the current crisis in US education, it seems particularly important to ensure that education is not compromised in the name of preventing extremely rare instances of school violence that are nearly impossible to predict,” says Kelly Welch, a criminologist at Villanova University in Pennsylvania.
