Killology
Col. dave grossman is the head of the killology research group which studies the psychological cost of learning to kill. research focuses on police and military mental training and how violence in media such as television, video and arcade games, and movies lead to shootings in schools as seen in columbine, jonesboro, and paducah. speakers are available for training to minimize trauma and stress faced by law enforcement agents who use handguns and witness murder in the line of duty and seminars explaining how graphic portrayal of violence in the media desensitizes youth and enables them to successfully commit crimes of mass murder.
