It's terrorism. Its purpose is to let us know that we have entered a
place where the forces of disorder are winning, and law and order
can't protect us. The authorities couldn't protect the train from
being vandalised, and they can't protect us from being robbed, raped
or murdered. Its aim is to make us afraid. Graffiti doesn't have the
potential or even the aim of making the lives of the downtrodden
materially better, and so is not a defensible political act.

Why don't you emigrate to Singapore - I'm sure you'll feel a whole lot
better there.
