What to do when your neighbors have carried out crimes against humanity.

Faced with a lack of prosecution of those accused of crimes against humanity committed during Argentina’s military dictatorship, family members and descendants of the country’s estimated 30,000 disappeared took action. In the mid-1990s, they began gathering outside of accused perpetrators’ homes and workplaces to publicly shame them and raise awareness about the government’s systematic and brutal targeting of its people — and how it had gone unpunished. The human rights group HIJOS (Sons and Daughters for Identity and Justice Against Forgetfulness and Silence) led and labeled this direct-action style of protest “escrache,” or exposure.
