Former hostage Clara Rojas arrives at Bogota's central square to attend a protest march in Bogota July 20, 2008. Colombians took to the streets in large numbers on Sunday to protest kidnappings that have plagued the country during its 44-year-old guerrilla war. Declaring that this year's Independence Day should be renamed "Freedom Day" for 2,800 people held captive in remote jungle and mountain camps, thousands were expected to march in cities throughout the country.
