Antanas Mockus had just resigned from the top job of Colombian National University. A mathematician and philosopher, Mockus looked around for another big challenge. Mockus, who had no political experience, ran for mayor of Bogot. Mockus turned Bogot into a social experiment just as the city was choked with violence, lawless traffic, [and] corruption. People were desperate for a change. The eccentric Mockus, who communicates through symbols, humor, and metaphors, filled the role. When many hated the disordered and disorderly city of Bogot, he wore a Superman costume and acted as a superhero called Supercitizen." People laughed at Mockus' antics, but the laughter began to break the ice. Mockus ... finished his second term as mayor this past January. The fact that he was seen as an unusual leader gave the new mayor the opportunity to try extraordinary things, such as hiring 420 mimes to control traffic in Bogot's chaotic and dangerous streets. He launched a "Night for Women" and asked the city's men to stay home in the evening and care for the children; 700,000 women went out on the first of three nights. Mockus sees the reduction of homicides from 80 per 100,000 inhabitants in 1993 to 22 per 100,000 inhabitants in 2003 as a major achievement. Yet Mockus doesn't like to be called a leader. "To me, it is important to develop collective leadership." Most important to Mockus was his campaign about the importance and sacredness of life. "In a society where human life has lost value," he said, "there cannot be a higher priority than re-establishing respect for life as the main right and duty of citizens."
