i total agree with Dahir Alasow in his theory that forgei hands behind killing of family. Let me tell you story after Iraq war in 2003, Iraq government had arrested forgein people who Burnt Shia mosque and accused the crime of Sunni people and later did the same (burning) Sunni mosque. The reason behind that is continuing state of hate between Shia and Sunni thus the atmosphere of mistrust between them. This technique is used by Egypt government to cover up any new decision. In case of Egypt the game is between Muslim and Christian.
