Research essay topic

My topic is street graffiti and the controversial question weather graffiti is a form of expression or vandalism. My prime exhibit is an on-line article from BBC News listing the pros and cons that come along with the world of graffiti art. One distinction that must be identified is the idea of illegal and legal graffiti that takes place. Private property is an obvious situation of where graffiti is vandalism but the question is what about graffiti that is painted on empty walls within the city. Areas where there is a sense of dullness and available space to paint on a wall. The exhibit recognizes this and sympathizes with property owners, but graffiti art is a form of expression. This expression creates communication and color to the city therefore not all graffiti art is vandalism.
