Gives a crude legitimacy to mass murder. These punks couldn't pull off flash fame on American Idol, on the athletic Field, in the corner bar, or with some hot chick; and they are desperate for ANY noteriety, even if it is from the grave. And the full-time infomercial surrounding us will give obligingly give it out.
This Conn. murderer went after small kids, probably because their optimism, innocence and general happiness was (in his eyes) a commentary on his failings, and hence threat. Perhaps motivated less by celebrity and more by revenge.
This kind of stuff will happen again, and no amount of prohibitionism will thwart it.
