Did you catch John Kerry's interview last week when he said he does not think Oswald was a lone wolf? He believes others were involved in the event, not necessarily in the shooting.

JFK Assassination Conspiracy Theories: John Kerry Has 'Doubts' Lee Harvey Oswald Acted Alone In Killing John F. Kennedy

I remember finding out about the shooting between classes on campus in the early afternoon. My French class instructor was really shaken up. He dismissed the class and the whole University closed in mid afternoon (EST).
The student center was mobbed with students as was the campus Chapel.
That was the Friday before Thanksgiving.
I went home to NYC & watched Ruby kill Oswald on TV on Sunday, which happened to be my Birthday. Most of the country was glued to the TV for the week. My school didn't resume classes until the Monday after Thanksgiving.

The NFL played on however ....
All regular programming was canceled. High school football games, college football games, all canceled out of deference to the tragedy. The AFL suspended its schedule that weekend as well.

But not the NFL. New commissioner Pete Rozelle nervously debated within his inner circle as to whether the schedule of games for Sunday, November 24th should be allowed to go on despite the death of the president. Rozelle even contacted the White House and spoke with press secretary Pierre Salinger to seek advice.

Salinger opined that President Kennedy, an ardent football fan, would have wanted the games to go on. How he knew this was anybody’s guess as JFK’s thought processes came to a sudden and violent end when the third bullet exploded his head during that fateful motorcade.

But even the President’s own brother, attorney general Robert F. Kennedy, was said to have agreed with Salinger and told Rozelle that the Kennedy Family would not be offended if the football games were played on Sunday while the President’s body lay in state inside the Capitol Rotunda.
