How the language of a Cho may reveal a greater truth...

I feel like I've kind of been slacking recently by just posting links to blogs but I keep finding interesting ones like this one on the Economist's blog on theories behind what might have made Seung-hui Cho snap at Virginia Tech. I'm not sure what I think about the writer, John McWhorter, based on his other articles, but I think he raises a point or two worth taking a look at a little more closely. Thoughts? Feel free to post your opinion...
