This is Marina's very first interview with the press after the assassination. It's very touching. You can't help but feel sorry for her. She said at the time that she believed Lee did it, that she didn't want to believe it, but she couldn't deny the facts. But, she had been under a long intense period of heavy influence and total control after the assassination, as you know.
She also spoke of having loved Lee, and she said that she visited his grave one or two times a week. Would she have done that if all stories about wife-beating were true?
But, the most telling thing about the interview was her denial of having any idea that Lee was going to do such a thing. She could have said, for instance, that he spoke badly of Kennedy, but she didn't say that, and he didn't say that. The fact is that Oswald killing Kennedy was a crime completely lacking in any motive. Not even a little one. Note even a remote one. Here's the interview. As I said, it's very touching.
