Wrong, research a little. Mary Jo was engaged, a professional, uptight about sexual matters, and a devout Catholic. She asked for a ride from a monster, thinking he was a friend. She was, and is, blameless.
I agree that Mary Jo is and was blameless. But that night, she would not have left her girlfriends and her purse. I believe they had all been drinking, and perhaps the dashing Senator had flattered her and wished to show her a special part of the island, a lovely beach or a private cove or some such. The ferry had long since stopped running, and the two left extremely quietly from the house of merriment.
The best that could have happened to her that night was to sustain a few beachside gropings from the famous Senator. As odious as that might seem to some of us, one does live on thereafter.
That’s the story...and I still don’t believe it. Anyone who worked for the Kennedy’s is suspect. That she didn’t have a “reputation” for extramarital affairs does not mean that she wasn’t capable of it. Anyone who worked for the Kennedy political machine is suspect for pretty much anything.
