It was bad enough that the Kennedy family had refused to release what were described as the private papers of the late Robert Kennedy. But then, last August, Boston Globe reporter Bryan Bender revealed that many of the papers were actually official documents from RFK’s time as attorney general, including some that may have pertained to assassination attempts against Cuban president Fidel Castro.

Yet the papers have still not been released. And, thus RFK’s son, Max Kennedy, who has acted as the family’s spokesman, earns his second Muzzle for stonewalling on the RFK papers (the first came in 2011).

According to an index obtained by Bender, the 62 boxes of files may contain crucial insights into such matters as the Kennedy administration’s anti-Castro activities, the Cuban missile crisis, and the Vietnam War. Max Kennedy said the family hoped to release all the papers. But one of the hold ups, according to the Globe, was the family’s desire to get a tax deduction for the papers before turning them over to the public domain.

As a Globe editorial put it, the Kennedy family “never should have been granted control over official documents in the first place. And they certainly shouldn’t feel entitled to a tax deduction for them.”

It’s time to see what’s in those files.
