Banksy

"In August 2004, the Keep Britain Tidy campaign issued a press release calling for zero tolerance of graffiti and supporting proposals such as issuing "on the spot" fines to graffiti offenders and banning the sale of aerosol paint to teenagers. The press release also condemned the use of graffiti images in advertising and in music videos, arguing that real-world experience of graffiti stood far removed from its often-portrayed 'cool' or 'edgy' image.

To back the campaign, 123 MPs (including [then]Prime Minister Tony Blair) signed a charter which stated: Graffiti is not art, it's crime. On behalf of my constituents, I will do all I can to rid our community of this problem. However, in the last couple of years the British graffiti scene has been struck by self-titled 'art terrorist' Banksy, who has revolutionised the style of UK graffiti (bringing to the forefront stencils to aid the speed of painting) as well as the content; making his work largely satirical of the sociological state of cities, or the political climate of war, often using monkeys and rats as leitmotifs."
