Sadly, the shooter is usually trying to solve what he (and it is virtually always a he) sees as a serious problem: social acceptance. Rampage shootings are generally the last act, not the first, in a series of attempts to change a damaged reputation. The shooter is rarely a loner. He is, rather, a "failed joiner," someone who has tried, time and again, to find a niche, a clique, a social group that will accept him, but his daily experience is one of rejection, friction and marginality. These experiences are amplified by social media: Facebook and its electronic cousins speed the damage done by teasing, stigma or outright bullying.
