Human rights supporters clash with riot police during a protest against the launch of a book on retired Chilean Brigadier Miguel Krassnoff in Santiago November 21, 2011. The book celebrates Krassnoff's work while he was in the Direccion de Inteligencia Nacional (DINA), the secret police during Chilean dictator Augusto Pinochet's regime, according to local media. Krassnoff is currently serving 144 years in prison from 23 sentences for the kidnap, torture and murder of Pinochet's opponents. REUTERS/Ivan Alvarado (CHILE - Tags: POLITICS CIVIL UNREST)
