The 2011 Egyptian Protests

Despite heavy-handed security measures, Copts and Egyptians broadly have accused the Egyptian government of negligence, failing to provide adequate security when a bomb exploded on New Year's Day in front of an Alexandria church, killing 23 Coptic Christians. It was suspected to have been detonated by the Gaza-based Army of Islam. Following the attacks many Christians protested in the streets, with Muslims later joining the protests. After clashing with the police, protesters in Alexandria and Cairo shouted slogans denouncing Mubarak's rule.
Police brutality
A leaked US embassy cable from 2009 described police brutality, including torture, as common and pervasive, and the government's efforts to combat it as ineffective and lacking in political will. The Egyptian Organisation for Human Rights has documented 567 cases of torture, including 167 deaths, by police that occurred between 1993 and 2007. On 6 June 2010 Khaled Mohamed Saeed died under disputed circumstances in the Sidi Gaber area of Alexandria. Multiple witnesses testified that Saeed was beaten to death by the police. Mohamed ElBaradei, former head of the International Atomic Energy Agency, led a rally in Alexandria against alleged abuses by the police and visited Saeed's family to offer condolences.
