Cases of vandalism are cited. It is considered a global epidemic. A Düsseldorf conservator notes that the subject is not often openly discussed because aggression against art can be triggered by discussion of it. Research is skimpy. A 1983 book by German and Swiss researchers maintains that the majority of attacks are against modern and contemporary works and works that are publicly owned. Specific targets are selected by vandals. Lack of understanding of modern works may cause an assault. Another case is tracked of fury over cost of contemporary works. The problem is exacerbated by the movement to democratize art and place it in public spaces. More art education in primary schools is suggested as a means to reduce future aggression. Art transport people may also willfully damage works for the same reasons vandals may. Broad masses of people must be helped to appreciate and understand art to reduce the threat. -- AATA
