In the early afternoon on Wednesday, as deadly clashes in Egypt drew into their seventh hour, I found myself sitting with three of my colleagues in an apartment overlooking the southern entrance to Rabaa al-Adawiya, in Cairo’s middle-class Nasr City neighborhood. In recent weeks, it had been the site of a sit-in protesting the removal of President Mohamed Morsi, a Brotherhood politician, from the Presidency in early July. On Wednesday, the area looked like a war zone.
