I see a difference between tagging (which just makes things look untidy)
and some rather more impressive designs which do make boring concrete
bridges etc. look more interesting. I don't have too much of a problem
with the latter - as long as it's only sprayed onto otherwise unused,
boring surfaces like concrete bridges. The former, or anything sprayed
where it will get in the way e.g. on a train, is just ugly.

To be honest - until you've actually hit someone in a 200ton train while
they've been spraying their 'art' all over a concrete bridge and killed
them, you've no real knowledge of the subject:

Simple fact: Graffiti perpetrators (and I deliberately refuse to use the
word 'artist' here) are breaking the law. They take it upon themselves to
cause criminal damage and delays. They trespass in areas they are not
qualified to be and do their utmost to cause the most havoc and disruption
while gaining all the notoriety they can with the minimal amount of effort.
Simple common sense - if you are not qualifed to be anywhere near a railway
line - don't go there - it's not worth losing your life, limbs or anything
else just because you want to write a four letter word over anything you
see.
