Uganda's top opposition leader Kizza Besigye's, second left, waves to supporters inside the court in Kampala, Uganda, Wednesday, March 28, 2012, after he was freed on bail. Besigye and his co-accused pleaded not guilty Wednesday to charges of convening an unlawful assembly in a case stemming from the killing of a policeman in violent street clashes last week. In tense scenes that threatened to turn violent, heavily armed police blocked supporters from following Besigye to the court. (AP Photo / Stephen Wandera) less
