Dropping Urns

I'm not one to condone the vandalising of works of art (especially portraits of Henry James), but I must say my sympathies are a little torn in the case of the chap who dropped an Ai Weiwei pot and smashed it. The incident - read all about it here - took place in a Miami gallery, where a man described as a local artist responded to an Ai Weiwie artwork by picking up one of the gaudily painted urns that constitute said artwork and, when challenged, dropping it to the ground and breaking it - just as Ai Weiwei is seen to do in the black-and-white photographs that form the backdrop to the gaudy urns. Indeed the whole kaboodle is titled Dropping a Han Dynasty Urn. According to Ai Weiwei, the gaudy urns are indeed of the Han dynasty, and a valuation of $1 million per urn has been put on them, whether as Han urns or as Ai Weiwei artworks is unclear. If they are indeed of the Han Dynasty, Ai has certainly done a good job of ruining them with that hideous paintwork.
  The 'local artist's' motives seem confused, his defence being that (a) he was making a protest about big-money international artists' work monopolising provincial galleries, and/or (b) that he got carried away, joining in the spirit of the thing by smashing an urn, just like Ai Weiwei. Perhaps things will become clearer later, but for now it looks roughly like this: Big-money international artist smashes valuable urn - that's Art. Small-time local artist smashes valuable (but hideously painted) urn - that's a crime.
