Since 2009, at least 177 of America's schools experienced a shooting. A parent should not have to worry when their children are at a public school in their city—whether it be an elementary school, a middle school, a high school, or a college campus. School safety and security are strengthened by prevention, mitigation, and response. The sections in this book educate school boards, school administrators, policymakers, academics, and parents on the importance of staying informed and accurately responding to school security and safety. The book highlights the school shootings in Columbine, Newton, Parkland, and many others that remind us of the responsibilities as citizens and communities to make schools a safe space for children. It is time to think about school shootings not merely as a problem of security but as a problem of security and education.
