FILE - In this Monday, Jan. 8, 2018 file photo, attorneys meet with Genesee District Judge Jennifer J. Manley as preliminary examination begins in the cases of four defendants, all former or current officials from the Michigan Department of Environmental Quality at Flint District Court in downtown Flint, Mich. Michigan’s attorney general in 2016 promised to investigate the Flint water scandal “without fear or favor” and pledged that state regulators would be locked up for fudging data and misleading the public about lead in the poor city’s pipes. Yet three years later, no one is behind bars. (Jake May/The Flint Journal-MLive.com via AP)
