Mark G. Levey: On September 11, 1973, Gen. Augusto Pinochet headed a military coup that overthrew the democratically-elected government of President Salvador Allende. Chile at that time was one of the world's oldest constitutional democracies.
In the months that followed, in a round up of "terrorists", Chilean military and intelligence officers arrested 30,000 Chileans and some foreign nationals. Virtually all were tortured, and 3,000 "disappeared", many dumped alive from military aircraft into the Pacific Ocean. The Junta's secret police also sought out its critics abroad, a few weeks later blowing up the former Ambassador, Orlando Letelier, in his car as he drove through downtown Washington, DC.
