Shortly after 911, Officer William Kasberg’s department was called to a week-long class about “Crisis intervention.” He thought for sure it was going to be a training on terrorism defense. When they announced that the topic was mental illness de-escalation and using non-violent techniques, he wondered if he was in the right room. Later in the training, a frail 70-year old lady started telling the group of police officers about her violent mentally ill son, and what could happen one day when they would have to intervene in her defense. Her talk changed everything: the way Kasberg understood his duty, and the way he could truly help people in his community. This in turn started a movement that completely transformed the San Antonio Police Department. This powerful presentation includes an actual demonstration of a crisis de-escalation with a teen girl who started cutting.
