FILE - In this Wednesday, Jan. 30, 2013 file photo, Egyptian riot police arrest a man during clashes with protesters near Tahrir Square in Cairo, Egypt. With near impunity and the backing of the Islamist president, Egyptian police have over the past week used excessive and often deadly force against protesters across much of the country, regaining their Mubarak-era notoriety as a tool of repression. With nearly 60 people dead and hundreds injured, police have re-emerged as a significant political player after spending the past two years on the sidelines. (AP Photo/Khalil Hamra, File)
