Synopsis
This manual introduces a standardized diagnostic system for classifying violent crimes, including murder, arson, and sexual assault.

The system provides a common terminology and framework for understanding perpetrators and victims, enabling police departments nationwide to coordinate efforts and solve crimes more effectively.
