Every time we say never again, it happens again.
A first-grade classroom in Newtown. A hallway full of armed officers in Uvalde. A movie theater in Aurora. A gay nightclub in Orlando. A music festival in Las Vegas. A young woman crying on the side of a Utah road before she is strangled in the wilderness.
We know these cases. We don't know why our systems keep failing to stop them.
This book is about that gap.
FAILED PREVENTION (Book 2 of the series) takes you inside ten of the most infamous tragedies in modern America-not to relive the horror, but to expose the system design flaws that made them possible:
Uvalde and Sandy Hook - where years of warning signs, school failures, and broken door policies ended with children trapped in classrooms and no one coming in time.
Virginia Tech and Aurora - where students told counselors and professors enough to scare them, then walked out of therapy and straight into planning.
Isla Vista and Pulse - where misogyny, hate, and extremist posturing triggered welfare checks and FBI files... that were quietly closed.
Fort Hood and the Boston Marathon - where names were in intelligence systems, emails were in FBI inboxes, and still the bullets and bombs went off.
Las Vegas - where a 64-year-old gambler legally built a private arsenal and turned a hotel suite into the deadliest single-shooter attack in U.S. history.
- Gabby Petito - where a 911 caller reported a man slapping a woman, officers watched the body-cam footage we all saw later, called it a mental health break, and drove away.
Who this book is for
If you are a teacher, school leader, cop, dispatcher, clinician, campus staff, security professional, policymaker-or the person in your group who always asks But what if?-this book will give you language and examples to push for real change.
It will also speak to you if you're simply tired of headlines that say unimaginable tragedy, when what they really describe is a very predictable system failure.
Book 2 is part of a larger project:
Book 1 asked why our institutions fail to solve difficult, high-profile cases.
Book 2 (this book) asks why they fail to prevent violence when the warning signs are right in front of them.
Book 3 - UNCHECKED: When Accountability Fails (coming next) turns the camera on the institutions themselves: what happens after the reports, the apologies, and the promises-and why so many agencies keep making the same mistakes anyway.
If you've ever looked at a school shooting, a terror attack, a mass shooting, or a domestic-violence murder and thought, We saw this coming, so why didn't anyone stop it?, FAILED PREVENTION will show you the answer-and what has to change so we don't keep asking the same question forever.
