Ethnographer George Richards talking to Ms Boyko makes a good case for international legal change concerning antiquities:
"Tightening up the legislation"
"The international legal framework needs to be strengthened"
"Improving the legal framework, needs to transcend countries and political rivalries"
The 1970 UNESCO Convention is obviously far from adequate in today's world. Perhaps the best thing UNESCO can do as their response top the current crisis is to call a meeting and try to thrash out a new one. They could do worse than invite Mr Richards to be its chair.
