Representatives from President Trump’s Federal Commission on School Safety just met in Cheyenne, Wyo., for their third public listening session aimed at reducing violence in schools. In these meetings, people have called for arming teachers with guns, hiring more counselors, putting more officers on campuses, and throwing more money at the issue. But none of these types of proposals address the root of the school safety problem.

A just-released study by Harvard University’s Dr. Dany Shakeel and I suggests that private school vouchers could be tickets to safer schools.
