Harvard Protects its Own?

This is how the AIA has described the public testimony of Prof. Carmen Arnold-Biucchi of Harvard at January's CPAC meeting:

"Carmen Arnold-Biucchi, representing the Harvard Art Museums, noted that she was not arguing against collecting coins, but that the looting on the island was now such a problem that extraordinary steps must be taken to combat the loss of knowledge that comes when coins are taken out of context."

Professor Biucchi's and Harvard's appearance at this CPAC meeting was unexpected. The Harvard Coin Collection has been the beneficiary of money and donations from both dealers and serious collectors, and it contains thousands of unprovenanced coins of the sort Arnold-Biucchi apparently now condemns.

Interestingly, Nicholas Burns, the former Undersecretary of State who apparently ordered import restrictions on Cypriot coins over CPAC's objections as a "thank you" to Cypriot advocacy groups who had given him an award is now a professor of "good government" at Harvard.

Why did Harvard and Arnold-Biucchi now decide to provide vocal support for import restrictions on Cypriot coins? Was it done to help protect Nicholas Burns' reputation?
