"They-can't-touch-you-for-it"-legitimacy in Museums

'For nearly three decades, the Nancy Wiener Gallery has sold Asian art to private collectors and museums, including the Metropolitan Museum of Art, Asia Society, the Los Angeles County Museum, the Art Institute of Chicago, the Nelson-Atkins Museum, the National Gallery of Australia and the Asian Civilizations Museum in Singapore, according to her website'.

Presumably now all these institutions will be encouraged to make available the details of which objects in their collection were from this source and of their previous collecting histories as presented by the seller. I bet though they will not be doing the same for the other items they bought from her fellow dealers who have not (yet) been caught out. 

An expression of "They-can't-touch-you-for-it"-legitimacy in its purest form.
