President Kennedy just before he was assassinated on November 22, 1963.

From the Wall Street Journal:

"WASHINGTON—President Donald Trump said Saturday morning he intends to allow the scheduled release of classified government documents about President John F. Kennedy’s assassination, though he left open the possibility that some could still be withheld."

"Among insights JFK scholars are hoping to gain from these documents is why assassin Lee Harvey Oswald made a trip to Mexico City weeks before the killing. The Warren Commission, which investigated the assassination, found Mr. Oswald’s visits to the Soviet and Cuban embassies there were an attempt to get visas that would allow him to enter those countries, but many details about the trip remain unknown."

I was a freshman in high school when this horrible thing happened. Everyone was upset. I saw a teacher who couldn't stop crying. I think it was about 3 days later and Oswald was killed which I watched on TV as it happened. In the same decade Martin Luther King and Robert Kennedy were murdered, there was a war in Vietnam, and we walked on the moon.
