   While scrawling graffiti is seen as a crime in the UK, yet in the US it has become a recognized art form\.  
   Just a few weeks ago eight graffiti gang members were convicted of causing £5,000 worth of damage on the London Underground\. They are among more than 70 hard\-core graffiti artists thought to be operating in London today\. Most are aged under 20\.  
   Graffiti artists, or ‘graffers’, operate in many British towns\. They often work at night, covering walls, trains and railway stations with brightly painted murals or scrawls in spray paint and marker pen\.  
   Some people regard graffiti as a form of vandalism and a menace\. London Underground says that railusers find it ugly and offensive\. It spends £2m a year dealing with graffiti, and has even introduced trains with graffiti\-resistant paint\. “We don’t think it’s artistic or creative – it’s vandalism\. It’s a huge nuisance to our customers, and it’s ugly and offensive,” says Serena Holley, a spokeswoman for the London Underground\. “It creates a sense of anarchy and chaos,” says Richard Mandel, a barrister who prosecuted the graffiti gang\. “Passengers feel as if the whole rail system is out of control\.”  
   British Transport Police has a graffiti unit designed to catch graffers in the act\. It spent five months tracking down the recently prosecuted gang\.  

Graffiti art can also be a dangerous pastime. The London Underground says that some teenagers have died in accidents during nocturnal graffiti ‘raids’.
However, others say that graffiti at its best is an art form. Art galleries in London and New York have exhibited work by increasingly famous graffiti artists. “Of course graffiti is art.
There’s no question about that,” says David Grob, director of the Grob Gallery in London. Even some of those who think graffiti is wrong admit that graffers are talented. “It’s just that their artistic talent is channeled in the wrong direction,” says Barry Kogan, a barrister who represented Declan Rooney, one of the gang members.
There is a difference between ‘good graffiti’ and vandalism, says Dean Colman, a 24-year-old graffiti artist. “I’d never spray private property, like someone’s house. Some graffiti are disgusting. There’s a big difference between that and graffiti which can brighten up grey walls.”
Dean makes a living as a graffiti artist. His days of illegal spraying are behind him, he says. He has worked on a television programme about graffiti, designed a series of government posters, and decorated nightclubs. He has exhibited his work at Battersea Arts Centre in London, and he has taught graffiti-spraying in youth clubs.
Dean sees himself as an artist, and thinks that graffiti art does not get due recognition. “There’s no graffiti art in the Tate Gallery and there should be,” he says. “Graffiti is a valid as any other art form.”
