![Bill Allen FILE - Chief Justice Earl Warren speaks at the Washington National Archives during a ceremony marking the 175th anniversary of congressional passage of legislation establishing the federal judicial system in the U.S., on Sept. 22, 1964. Seventy years ago, no one outside of the U.S. Supreme Court building heard it when Warren announced the historic Brown vs. Board of Education decision on school desegregation. Now, through the use of a voice-cloning technology, it is becoming possible for people to “hear” Warren read the decision as he did on May 17, 1954, along with oral arguments by lawyers.

![Peter Bregg FILE - Children smile from window of a school bus in Springfield, Mass., as court-ordered busing brought Black children and white children together in elementary grades without incident, Sept. 16, 1974. Friday, May 17, 2024, marks 70 years since the U.S. Supreme Court ruled that separating children in schools by race was unconstitutional. On paper, Brown v. Board of Education still stands. In reality, school integration is all but gone, the victim of a gradual series of court cases that slowly eroded it, leaving little behind.
