Some graffiti is breathtakingly beautiful, some is gloriously witty (think:
Banksy). Some of it can really brighten up a boring journey, or make a
disused train a work of art.

Admittedly, some of it - such as the stupid tags (think: TOX) are utterly a
waste of time and yes, certainly vandalism. But I don't think we should tar
all grafitti artists with the same brush here.

I don't know which kind these were - and the loss of life is tragic whether
they were the witty ones or the wasteful ones - but please don't diss all
grafitti artists as being vandals or degenerates. Some of it is really
quite beautiful.
