The National Archives is refusing to release 1,171 classified CIA documents related to the assassination [of President John F. Kennedy] in time for the [50th] anniversary as it had promised. In 2010, deputy archivist Michael Kurtz announced that the secret records would be declassified by November 22, 2013. But the National Archives has since [retracted] that promise in a letter to Jim Lesar of the Assassination Archives and Research Center, who requested the release. [This] frustrates Lesar, whose nonprofit is devoted to collecting and disseminating information about political assassinations. "In 1992, Congress unanimously passed legislation that was designed to get all of the JFK assassination-related records released," he said. "There was supposed to be only a very few records whose release could be postponed for periods of time including up until the year 2017, but basically everything was supposed to be released well before then." Of course, the CIA and National Archives won't say exactly what is contained in the documents, not even the number of pages. "The National Archives does not have a page count, but it appears that there are at least several thousand pages that are still being withheld, and they appear to be on some very important subjects." The CIA and National Archives' intransigence certainly doesn't help deflate the bubble of speculation about what really happened at the Grassy Knoll. It's been 49 years. Most of the people involved are dead. What's to hide, unless the government is shown in an embarrassing or criminal light?
