Someone needs to make the point (that was so successfully made in New York) that out-of-control graffiti lowers the quality of life for everyone, and is a "gateway" crime. Not to mention embarassing.....esp. since the Germans have had such a pristine reputation for "neat, clean & orderly".

Since it's now so prevalent, it has undoubtedly escalated into an expensive problem, but dismissing it as art or nuisance is ignoring the larger problem, i.e. acceptance of a crime.
