More than 50 years after President John F. Kennedy was slain in full view of the world, the final government documents about his death are set for release. The documents are among the last of still-secret papers the government amassed on the assassination. Some grand jury and tax documents will remain secret. The JFK Records Act passed in 1992. The law mandated the government release the remaining files to the public and gave it 25 years to do so. October 26, 2017 ... is the deadline for full release. The National Archives said government agencies had deemed files covered by the act prior to its passage too sensitive for release. They run the gamut from FBI to CIA materials and all manner of documents said to pertain to investigations into Kennedy's death. The Archives said the full collection ... spans millions of documents. Many files have been released about the Kennedy assassination over the years, including some in redacted form. Barring a waiver from the President, the obscured text will be revealed. The full release of the documents would mark the end of a decades-long struggle for researchers to get a hold of all available information. A Gallup poll in 2013 showed 61% of respondents said more than one person was involved in the shooting and some pointed to the Mafia, the government, the CIA, Cuba and others as playing a role.
