The crisis over the Detroit Zoo has left many wondering about the city’s leadership. Last weekend City Council essentially voted to close the zoo rather than give up control of its operations to the Detroit Zoological Society. Since then Mayor Kwame Kilpatrick has been conspicuously absent; he’s been with his mother U.S. Representative Carolyn Cheeks Kilpatrick on a congressional fact-finding trip in Africa. That’s brought up questions of just what leadership roles a city’s elected representatives should play. Michigan Radio’s Jack Lessenberry spoke with Retired Michigan Appeals Court Judge Roman Gribbs, who was mayor of Detroit in the early 1970’s.
