Three years and four presidents later, Bolivia's bloody October 2003 uprising _ a blast of popular discontent that helped propel the first indigenous president to power _ is still an open wound. Relatives of those killed are frustrated that no one has been brought to justice. And the poor are waiting to see real changes in their lives. (AP Photo/Pablo Aneli)
