Two African-American couples were murdered in Walton County, Ga. in 1946, as a large crowd of people looked on in what is considered to be the last mass lynching in American history. A grand jury was convened, but no one was ever charged even after 16 days of witness testimony. Seven decades later, can the transcripts be released to a historian?: Yes; though grand jury records are usually kept under seal forever, these can be released as a matter of exceptional historical significance. Dissent: The rules clearly prohibit the disclosure of these materials. Imagine the harm that might come to descendants of the suspects, witnesses, and grand jury members when all is revealed.
