One of my sons is fascinated by the Kennedys, has read a few books about the dynasty and apropos of "Madmen" and the music of the time he's very interested in that whole era, civil rights etc. and often asks me about what I remember. Not a lot from the early 60s because I was quite a young child, although I recall having heard about the assasination on the radio when it happened, my mother was next door and had just come in and I announced it to her, she hadn't heard and was so visibly shocked and upset I wish I hadn't just blurted it out. JFK resonated so much with my Catholic parents and the hope he inspired at the time, it was like a small light going out in their lives.
There are so many conspiracy theories surrounding the Dallas shooting and the alleged phone call to a regional newspaper in England, 25 minutes before the event, advising some "big" news was coming out of America that just adds to those.
