A former board member feels that the Columbia City Council is not doing enough to bring more diversity to the Citizens Police Review Board. COLUMBIA - During last Mondayâs Columbia City Council meeting, an issue involving the lack of diversity within the cityâs Citizens Police Review Board was brought up by Cornellia Williams, a longtime Columbia resident and former member of the review board itself. âBill Davis, Baxter Nickels, Daryll Smith and I were part of the board in previous years since 2009,â Williams said. âIt was very diverse then and now there are absolutely not minorities on the board.â
