An Egyptian opposition protester holds up the head of a sheep as tens of thousands gather outside the Presidential Palace calling for the ouster of Egyptian President Mohammed Morsi on July 2, 2013. Opponents of Morsi poured onto the streets of Cairo to press their demand that he step down after the Islamist president snubbed an ultimatum from the army to agree to the “people’s demands” or face an imposed solution.

I’m not sure if you’re aware of the symbolism behind the sheep’s head. Brotherhood members and their supporters are perjoratively referred to as “kherfan” or “sheep” by their opponents, partly due to the Brotherhood doctrine of “el-samaa’ weltaa’a”, which very loosely translated means “submission to the will of the leadership”.
