Jailed Venezuelan opposition leader Leopoldo Lopez calls for more protests

Locked up and denounced by Venezuela's government as a terrorist, Leopoldo Lopez may be out of sight, but he is not out of mind. Building-sized posters of the charismatic opposition leader shouting, with his fist pumped into the air, dot wealthy Caracas neighborhoods. The same image can be found stenciled on the walls in the pro-government slums, but below the word "Murderer."
