People get blown up by the hundred every day. Whether it's an Iraqi market, Afghan policemen or Boston runners, this sick psychotic behaviour is probably the signature of modern times. We are infested with sick ideologies, and it will only get worse. It's just a footnote in a severely depressing roll-call of ideological carnage without end. And don't worry, whatever scum are responsible, you'll find plenty - maybe even some on here - who will apologists for it.
There's already talk of ramping up security for the London marathon, but ateotd you can never stop the nutters, and whatever extra disruption they cause is viewed by them as a bonus.
I don't have any answers. All I expect is regular doses of the same, for the foreseeable, as well as mudslinging as to why it wasn't prevented, and doubtless conspiracy theories that Bush did it.
What a mean old scene.
