I'll admit, I think an ounce of prevention is better than a pound of cure 99.9% of the time, but in this case, I have to disagree.
A book was recently published, "Why Kids Kill: Inside the Minds of School Shooters" by psychologist Peter Langman. He's been researching the phenomena of school shootings basically since the one in Olean, looking into their personal lives, reading their diaries, police reports, etc, and according to him, there's one thread that connects all of them.
They were all mentally ill.
This is not a case of bullied kids acting out. These are cases of psychopaths and sociopaths performing acts that they saw no objection to. Reasoning with a sociopath is impossible, it's the definition of the illness.
While I agree that these children need help, "reaching out" to them is not going to stop them. They need to be diagnosed and treated for the disorder that they have. While I agree that the drill here is a bit of a farce, I don't think the time would have been better spent attempting to pick out potential shooters and share our feelings with them.
A controversial opinion? Perhaps. Perhaps it's cynical to believe that there are people out there who want to harm others for reasons that can only be described by others as "illogical."
But explain that to Eric Harris and Dylan Klebold's victims.
