Just over two weeks since Rachel Corrie was killed - and in today's paper I came across this run down on some of the ways some people on the Internet have been trying to finish off what the bulldozer did to her.

Here's how columnist John Sutherland in the Guardian concludes his piece"What have we come to? The speed with which this kind of devil's advocacy can now (thanks to the net) be mounted, its sheer unbridled violence and its moral irresponsibility are, to the thoughtful mind, more frightening than any of those WMDs for whose (dubious) existence Britons are, at this moment, laying down their lives. Stop the world: I want to log off."

I can imagine how a young man driving a bulldozer could fail to keep a proper look out, and not see what he was doing, if that's how it was; I can even just about imagine how it might happen that someone in that situation could get twisted up so that maybe he didn't even care what he was doing, if that's how it was.

But my imagination just can't take in the way people, sitting safe in their homes, in front of their computers, can find it within themselves to write stuff like that. What happens in the lives of people to make them that way?
