Nice post SC.
Several thoughts:
1. I don't think we. will ever know who killed JFK concusively.
2. There are too many holes in the Warren Commission Report, for Oswald to have done this.
3. Events happened so fast, as they did when Lincoln was shot. The first woman to be hung, (Mary Surratt), was holding a package that John Wilkes Booth gave her and she was hanged as part of the conspiracy. She was innocent.
4. If someone really great gets elected, someone who disagrees with them in one form or another will probbaly kill him/her.
5. Arguing politics, is like, "two drunks on the Titanic, arguing over who's going to pay the bar bill".
This tradgedy seemed to have jolted all of America to a realization that is still felt after 50 years. Times of innocence were lost, and we started to live in a totally different world.
