In 1973, Gen. Pinochet overtook Chile in a violent coup. In 1998 came the surprise arrest of the former Chilean dictator for crimes against humanity. Armed with a diplomatic passport and apparent immunity, the retired general visited Great Britain for a vacation that was to forever change his life -- and the prospects for dictators across the globe. Amnesty International spearheaded the long-awaited arrest with help from the Spanish and British governments, but faced a pro-Pinochet publicity campaign masterminded by one of the dictator's few allies, former Prime Minister Margaret Thatcher. As the dissenting faction pushed for an extradition trail, 500 days passed with Pinochet held under house arrest in an exclusive suburban London community.
