In Missouri, the American Civil Liberties Union has filed a federal lawsuit against the school district in an area made famous by the police shooting of African-American teenager Michael Brown. The lawsuit accuses the Ferguson-Florissant School District of using an election process that dilutes the African-American vote. While more than three-quarters of the district’s students are African-American, there is just one black person on the seven-member school board. The suit seeks a change that would let voters choose school board members who reside in their district.
