I was fascinated by this article in the Sunday Times today and by the ongoing and fairly balanced debate on the website.
What is worrying is that in this article, and elsewhere in the media, Cho has been described as having had autism, apparently based solely on an interview with an elderly relative in South Korea. Perhaps time will tell if that is correct, but what is clearer is that Cho Seung-hui had mental illness. Autism is a developmental disability, not a mental illness, though it can co-exist with mental health problems just as mental illness can co-exist with any other condition. It would be very sad if autism were to be prematurely blamed for this tragedy. Read the view of the National Autistic Society here.
Jackie also pointed out in my comments that Lionel Shriver's 'We need to talk about Kevin' is another book about a high school massacre. I have the book but because I know a little about the theme I haven't dared to read it yet.
