Robert Mackey reports: Activists in Cairo and Alexandria rallied on Wednesday on the second anniversary of the killing of Khaled Said, a young Egyptian whose death at the hands of police officers provoked outrage and acted as a catalyst for the wave of popular anger that eventually swept Hosni Mubarak from power eight months later.

As the Egyptian newspaper Al-Masry Al-Youm reports, Mr. Said’s mother, Laila Marzouk, said at his grave that she cannot bring herself to vote for either of the remaining candidates in Egypt’s presidential election.

According to an Egyptian blogger who writes as @TheMiinz, Ms. Marzouk told Al Watan, another Egyptian newspaper, that being forced to choose between Ahmed Shafiq, a retired general who served as Mr. Mubarak’s last prime minister, or Mohamed Morsi, the candidate of the Islamist Muslim Brotherhood, was like being asked to select one deadly disease over another.
