For the first time, the Zapruder film of President John F. Kennedy's assassination is shown in motion to a national television audience by Robert J. Groden and Dick Gregory on the show Good Night America, which was hosted by Geraldo Rivera. The viewing led to the formation of the United States House of Representatives Select Committee on Assassinations (HSCA), which investigated the killings of both Kennedy and Martin Luther King, Jr.

In the United States, the Supreme Court upholds a ban on racial segregation in state schools, colleges and universities. The University of North Carolina had been appealing an earlier ruling from 1954, which ordered college officials to admit three black students to what was previously an all-white institution. In many southern states, talk after the ruling turned toward subsidizing white students so they could attend private schools, or even abolishing public schools entirely, but ultimately, desegregation did take place.

After ratification by 43 nations, the Treaty on the Non-Proliferation of Nuclear Weapons goes into effect. Of the non-signatory nations, India and Pakistan acknowledge possessing nuclear weapons, and Israel is known to. One signatory nation, North Korea, has withdrawn from the treaty and also produced nukes. International atomic experts estimate that the number of states that accumulate the material and know-how to produce atomic weapons will soon double.

In England, twins Ronald and Reginald Kray are found guilty of the murder of Jack McVitie. The Kray brothers had been notorious gangsters in London's East End, and for their crimes both were sentenced to life in prison, and both eventually died behind bars. Their story later inspired a 1990 motion picture entitled The Krays.

British-born comic genius Charlie Chaplin, whose long and turbulent career in the U.S. had been brought to an abrupt end when he was branded a communist and denied a residence visa, is bestowed a knighthood at London's Buckingham Palace. Chaplin died two years later and even then peace eluded him, as his body was stolen from its grave for eleven weeks by men trying to extort money from the Chaplin family.
