I can understand the sentiment, but during the Arab spring, didn't a group of demonstrators attack and badly damage some of the items in an Egyptian museum.

My point is that despite all the oil protestors throwing shot at paintings, the measures where already taken to protect them by having them behind glass (though still prosecute the idiots).

If the extremist both religious and left are taken care of, then maybe we can talk about it as they are the ones to target history first. You can want items back but it's better to have them back in one piece and preserved than let them be destroyed.
