Jim Crow Is Resurrected in Mississippi

Earlier this month, white representatives in the Mississippi House approved a bill to create a new district—that includes all of the majority-white neighborhoods in Jackson, a capital city that is 83 percent Black. This includes creating a criminal justice system for the district, overseen by an all-white power base.

Under House Bill 1020, the white conservative chief justice of the Mississippi Supreme Court would handpick the new district’s two supervising judges; its prosecutors and public defenders would be chosen by the state’s white Republican attorney general

State Rep. Trey Lamar, the white Republican who sponsored the bill, lives in and represents a majority-white district more than two hours away from Jackson. (He holds a seat once held by his grandfather, Leon Hannaford, whose legacy includes introducing a 1962 bill to tighten residency requirements for college students, which a local paper at the time reported, “would have kept Negro James Meredith from filing suit to enter the University of Mississippi.”) In various statements on the House floor and in an op-ed from last weekend, the legislator has insisted that HB 1020, by adding unelected judges to Hinds County’s courts, will help clear up lengthy case backlogs, while an expanded Capitol Police force will address a spike in crime in Jackson, allowing his constituents to “feel safe when they come” to the capital.
