I didn’t see anything like this - but I don’t doubt that it occurred. I do remember When JFK was assassinated my grandmother saying, “Good. I never liked that SOB”.
My parents said something similar when JFK was shot, without the “SOB” part. We knew a lot about his antics that never was reported, as house staff of the Kennedy friends/neighbors went to my uncle’s church in FL. The Kennedys were pigs; all of ‘em.
