Hundreds of people, including many of Madison’s top business and community leaders, gathered Friday night to hear how a group of influential African-American residents calling themselves the Justified Anger coalition plans to lead a broad-based attack on pronounced racial disparities in the city. … “It’s African-Americans coming together in ways I’ve not seen in my 30-plus years in this community,” Darrell Bazzell, vice chancellor for finance and administration at UW-Madison, told the crowd in his welcome.
