Under a state of emergency enforced continuously for 30 years, Egyptian authorities can arrest anyone they choose on the mere suspicion that they might be a threat to public order and security. They can then detain them by administrative order without charge or trial for as long as they like. This report documents these patterns of abuse and the individual cases of many victims. Amnesty International is calling on the authorities to lift the state of emergency, repeal emergency legislation and end the corrosive system of administrative detention.
