Moving on to the last question, in my view is a better to arrange official street art graffiti events in order to prohibit graffiti vandalism. Firstly some people express themselves through street art and most of them are already penalise, but still drawing on the buildings. Moreover the official festivals can attract a lot of youth, which would have a new pastime. The town council should hold special events to graffiti artist and lovers, also designate abandoned buildings to the graffiti festivals. Due to such events can be reduce graffiti vandalism and graffiti can be use to decorate the streets of the city. However sometimes people nevertheless violate the legislations, therefore they should be punish and pay a fine. In conclusion, I still do believe that the best way to stop graffiti vandalism is to organize street art festivals.
