It is likely some combination of increased access to firearms, worsening forms of bullying (such as cyberbullying), the influence of violent revenge themes in the media and entertainment venues (e.g, music, movies, video games), the breakdown of the family structure, and the increased availability of subculture movements such as Gothic and Emo that foster a sense of alienation from mainstream society. None of these factors by themselves is likely to trigger a school shooting. For example, there are many Gothic children and people who play violent video games who do not commit school shootings but the more of these variables are present, I believe that the likelihood of a school shooting increases.
This story is clearly the writings of an angry and insecure individual who has strong revenge fantasies. The castle was likely a metaphor for his school and he was foreshadowing events to come. Unfortunately, as in many similar cases, no one put the pieces together before hand. In fact, four of his Facebook friends liked the story and 49 shared it with other friends. No one wrote a public comment of concern or disapproval. For a follow-up to this blog entry on TJ Lane, click here.
