Fifty-eight years after those gunshots rang out in Dealey Plaza in Dallas, the National Archives is about to reveal some of the secrets the government still keeps about the 1963 assassination of President John F. Kennedy.

On the surface, this moment — the imminent release of long-secret documents from a JFK assassination library — looks like a victory for transparency. The release, scheduled for Wednesday, revives a decades-old declassification process that stalled in 2017, when President Donald Trump failed to comply with a legal deadline to make the entire library public. The CIA, FBI and other agencies had protested to Trump that the documents revealed national security secrets that, half a century after Kennedy’s murder, were still too sensitive to be public.

In October, President Joe Biden announced he was restarting the process of declassifying and releasing the documents under provisions of a 1992 law, the Kennedy Assassination Records Collection Act. He scheduled this week’s release and another for next December — declaring the disclosures “critical to ensure that the United States Government maximizes transparency.”
