No, The Kennedys did not have Marlyn killed...
Don't accept on face value carefully placed stories (which even liberal historians have taken the bait on and run with) that JFK and RFK planned the Ngo brothers' murders and the failed Castro assassination plots.
Or Marilyn's death (although there's little doubt of the affair).
It's a scam. It's intended to conivince us that the Kennedys "got what they deserve" via blowback/rough-justice/bad-karma. So we'll care less about what happened to Jack and Bobby and ask fewer questions about why and by whom.
The media has accepted that as fact. Don't make the same error.
(Even Ted's Chappaquidick situation is stranger than it appears on the surface).
It is true that several of JFK's girlfriends were knocked-off, including Mary Pinchot Meyer in 1964 -- a year after Kennedy's assassination, and the Kennedy family wasn't the culprit... Meyer's husband was, in fact, CIA operative cord Meyer who later said, prior to his own death, that his wife had been murdered "by the same bastards that killed President Kennedy" (meaning, apparently, his own agency).
The same is likely true with Marilyn.
Unfortunately, however, it's much too easy to frame the famous people. It makes for a sexier story to the tabloids and public at large. And helps paint the victims of assassination as if they were themselvs assassins.
Once again, that's to make us care less what happened, and to ask fewer questions.
