Public mass killings are becoming more common. Though the chances of being harmed or killed in a mass shooting are slim, each incident affects the public's sense of safety. There are many myths and falsehoods concerning mass murderers. As a result, the public lacks reliable knowledge about the reasons behind such killings, preventing the development of comprehensive strategies to mitigate the violence. Written by a mental health therapist with thirty years of research experience in criminal psychology, this book clarifies the realities of mass killings. Using the research on psychological profiling, it provides a foundation for understanding the pathway to violence identified in the personal histories of many mass murderers. Drawing from criminology, neuroscience and developmental and social psychology, the author makes the case that we are all capable of creating a safer society.
