Oddballs are not the problem. They do not fit the profile. There is no profile. Attackers came from all ethnic, economic, and social classes. The bulk came from solid two-parent homes. Most had no criminal record or history of violence. The two biggest myths were that shooters were loners and that they “snapped.” A staggering 93 percent planned their attack in advance. “The path toward violence is an evolutionary one, with signposts along the way,” the FBI report said. Cultural influences appeared weak. Many perps shared a crucial experience: 98 percent had suffered a loss or failure they perceived as serious—anything from getting fired to blowing a test or getting dumped. Of course, everyone suffers loss and failure, but for these kids, the trauma seemed to set anger in motion. This was certainly true in Columbine; Dylan viewed his entire life as failure, and Eric’s arrest accelerated his anger.
