Placards with pictures of missing people are seen at a table as Mexican poet Javier Sicilia (C) attends a news conference at the Museum of Memory and Tolerance in Mexico City June 18, 2012. Sicilia announced a month-long procession called "Caravan for Peace" that will tour 25 cities of the U.S. starting on August 12 in San Diego and ending in Washington on September 10, local media reported. Human rights activists and families of victims of violence will take part in the caravan which is intended to draw attention to the erroneous policies of the war on drugs that have caused a crisis of violence and impunity in Mexico.
