Christians and police clash violently in Egypt

In the worst incident of violence in Egypt since President Hosni Mubarak was ousted in February, 24 people died, and more than 200 were wounded after a  protest in Cairo turned violent  on Sunday. Christians protesting a recent attack against a Coptic church in Aswan province  were attacked by police. Thousands filled the streets chanting, “the people want to bring down the field marshal,” in reference to Field Marshal Mohamed Hussein Tantawi and the military council that has ruled Egypt since February. David Kirkpatrick,  Cairo bureau chief for The New York Times, and  Youssef Sidhom,  chief  editor of Watani, the  Copt newspaper, talk about the incident, and what it means as Egypt heads into its first democratic elections.
