Praise for Warning Signs

"All educators who work with students from elementary school to college age will find tools in this book to recognize warning signs, encourage proper threat assessment, and ultimately avert a tragedy. Dr. Langman's research and work have saved lives. I know. Mine is one of them."

- Molly Bradley Hudgens, Congressional Medal of Honor Citizen Honors Recipient; author of Saving Sycamore: The School Shooting that Never Happened

"I wish I did not know Peter Langman. I wish his work did not matter to me, or any of us for that matter. But it does. My daughter Jaime was murdered in the Parkland school shooting. In hindsight, what happened to my daughter was preventable. This important book will take readers through identification of potential attackers and how to take action before the next mass shooting happens. For the safety of those you love, I hope you take the time to read this book."

- Fred Guttenberg, gun safety activist; author of Find the Helpers

"To say that Warning Signs is a must-read doesn't go far enough. This book should be required reading for every educator, school safety professional, and law enforcement officer in America. At a time in our history when we are faced with increased violence in our schools and communities, Dr. Langman provides a critical understanding of what we are facing and what we can do to make a difference. This book should be part of every school district's threat management program."

- John McDonald, Executive Director, Department of School Safety, Jefferson County Public Schools
