Former Richardson ISD school board trustee David Tyson, Jr., has sued the RISD, alleging its at-large election system is a violation of the Voting Rights Act of 1965. He wants RISD to change to single-member-districts, with at least one district being majority African-American, centered in Hamilton Park, a historically African-American neighborhood in RISD.
That led Carol Toler, in the Lake Highlands Advocate, to write about how the desegregation order in 1970 resulted in closure of the segregated school in Hamilton Park and the assignment of black students there to three different RISD high schools. That created diversity in those schools. RISD still benefits from that diversity today.
