There are often mixed messages in the media about graffiti and street art but essentially the definition between both terms defines one as criminal damage (graffiti) and the other as permission based artwork (street art).
The police defines graffiti vandalism as the defacing of private and public property without consent from the property owner. Graffiti vandalism can take the form of writing, drawing or scratching onto surfaces using different implements such as paint, markers, stickers, and stencilling.
StreetArt, unlike graffiti vandalism, is legal artwork where permission to mark the surface has been granted by the owner of the property. Street Art is often known under many names such as urban art or mural art. Street art projects on hotspot areas can be an effective graffiti prevention strategy.
