Masked police officers stand guard as residents stand in the doorway of their home in downtown Colon, Panama, Saturday, Oct. 20, 2012. Police began patrolling Colon after violent protests Friday over a new law allowing the sale of state-owned land to private companies already leasing land there to handle the import and export of goods in the duty-free zone next to the Panama Canal. Protesters want the government to instead raise the rent and invest the money in Colon, a poor and violent city. (AP Photo/Arnulfo Franco)
