It's a sad day today in London.

As usual, security measures will be further tightened pretty much everywhere, which will just make public transportation a little more difficult for everybody, and will not prevent in any way another attack. Apart from the foolish war that's going on in Irak, have our leaders a clue on what's going on and what to do? Tim Bray has a point:

I’m not saying that there’s any political grievance to which attacking New York, Madrid or London is a reasonable response. But when something is driving enough people into insane belief systems that we see regular explosions in our cities, it would be smart to care—a lot—what that something is. Because, on the evidence, I don’t think the leaders of the Western world have a clue.
