When the 'pickings' thin out...expect to see them manufacturing ancient artifacts.
"...after personally laying out $3000 on a 1st-century BC scroll being sold by Bedouin, the enormously respected Professor Hanan Eshel from Bar-Ilan University has found himself in the dock for handling illegally looted finds. The case continues, even though Eshel made the discovery known to the Israel Antiquities Authority and ought to be applauded for saving his country's cultural heritage for the State. One thing is clear: future Bedouin finds will simply disappear over the borders on to the antiquities market. Little has been learnt about managing the Bedouin since the Muhammad ed-Dib (the 'Wolf') found the first scrolls 400m above Qumran."
