I was saddened to see one of the £1.5 million new trains daubed in ugly graffiti at Brighton station.

Although the perpetrators of this pointless act will one day discover girls and settle down to a normal life, the question must be asked why there was no security at the site.

If gormless morons can spend probably at least an hour on their puerile activities, so could anyone inclined sabotage the train, with possibly catastrophic results.
