@topsy: And what, may I ask, do you suggest we do to this girl who may lack the mental fitness to understand her actions?; and, what, of her chaperone?; and of the museum staff? "Off to art jail for thee!" I agree, it's a damn shame, but this is the risk you take showing expensive artwork to the general public. The insurance company will slither in, they'll call this guy [www.newyorker.com] MoMa will proctor a competency exam for all future museum-goers, and someone will have a good story to tell about it.
