I think the “protestors” were angry at Zawi Hawass for a number of reasons. But at least one of them was that he was staunchly protecting Egyptian antiquities from being stolen out of the museums by protestors.
Some of the protestors no doubt would like to steal and sell that stuff in the museums. And some of them would probably like to destroy them, like the statues of Buddha, because they are “idols.”
I notice that the press has completely stopped talking about any danger to the Egyptian antiquities. Does this mean that they are now safe? Or does it mean that they don’t want to report that what the “protestors” are up to?
The only reason most of that stuff survived in Mohammedan Egypt is that it was safely buried under the sand until the British rule began. But if the Muslim fanatics return to power, they will predictably destroy it.
