Profile of a school shooter

By James Guliano

What motivates a person to shoot?

A school shooter has mental health problems. Many mass shooters are motivated by revenge or envy. In addition, killing often show risk factors that are usually tied to criminal behavier.

How do they plan for a shooting?

School shooters also tend to be constantly thinking about guns, violent games or movies. In order to kill innocent little children, it's possible the killer didn't have kindness or deeply caring, understanding feelings for them, instead seeing them as symbols of something he wanted to destroy, Langman said. Our culture and media (such a violent movies and video games) only reinforce the idea that manhood is about reaching power, and social and sexual status. Violence is honored and praised as a way to get that power, he said.
