The tragedies at Uvalde, Texas, and Parkland, Florida, have shown that our national strategy to end school shootings is failing. uniquely applies systems-thinking to school shootings as a cultural trend. Author Lisa Ross exposes not only the design flaws in our most celebrated prevention methods—active shooter response training, threat assessment teams, and target hardening but also the implicit and at times unwarranted assumptions on which they are based. America's makeshift approach to combating school shootings since Columbine is examined, with emphasis on the school resource officer's role. Then through the interdisciplinary themes of power, propaganda, and panic, Ross explores society's psychological processes for controlling social threats. What emerges is a near irreconcilable conflict between post-Columbine active shooter policy and traditional police culture, which is made plain by government investigations into law enforcement's response at Uvalde. Policymakers, school administrators, and researchers and students in the fields of social science will find this book sweeping, compelling, and relevant.
