Thus far I've only seen this one place, and the conclusions I draw from it are more strictly in line with something like Crane Brinton's typology of popular revolutions than anything else, but that we consider supporting regimes where this is tolerated is . . . ah . . . quite a damn problem:
A Sky News Arabic correspondent in Cairo confirmed that protestors belonging to the Muslim Brotherhood crucified those opposing Egyptian President Muhammad Morsi naked on trees in front of the presidential palace while abusing others. Likewise, Muslim Brotherhood supporters locked the doors of the media production facilities of 6-October [a major media region in Cairo], where they proceeded to attack several popular journalists.
