Shortly after the Apr. 20, 1999 Columbine High School massacre, I was privileged to address audiences throughout America on leadership, violence prevention, and crisis planning.
During these presentations, I shared reflections with law enforcement, educators, mental health professionals, private security, students, government officials, and community leaders. These reflections crystalized concerns that violence in America would intensify not only in schools, but in workplaces and communities, against police, in houses of worship, and by acts of terrorism.
