Michael Roleplays a Super Embedded Person Whose Profession Is An Influencer

As a forward and not presented simply as legalistic cop out phrasing, this is my opinion on how I would handle the matter of any president being killed so long as we had the proper line of succession available.

The announcement: Made by someone.

12 hours go by...

Play the Garry Kasparov vs IBM's Deep Blue card where the winners of the chess match didn't really gloat.  I would just speak with head down saying very simply "Twelve hours have passed since the president died.  After another twelve, I'm voting that the proper chain of command gets activated.  During these twelve hours you are welcomed to reflect on all that that man or woman was during their life times.  Thank you for your patience with me during this, one of our darkest hours."

After the other 12 hours: "I vote that the chain of command becomes active."

(***Given the time period of the Kennedy assassination, I agree with the hundred minutes they waited before the inauguration of former president Johnson.  Why leave the entirety of the country in worry for so long.  I'd likely send someone to notify that the situation is stable and that there is an upcoming announcement.)
