Today’s Highlight in History:

On Feb. 18, 1970, the “Chicago Seven” defendants were found not guilty of conspiring to incite riots at the 1968 Democratic national convention; five were convicted of violating the Anti-Riot Act of 1968 (those convictions were later reversed).

On this date:

In 1564, artist Michelangelo died in Rome.

In 1972, the California Supreme Court struck down the state’s death penalty.

In 1983, 13 people were shot to death at a gambling club in Seattle’s Chinatown in what became known as the Wah Mee Massacre. (Two men were convicted of the killings and are serving life sentences; a third was found guilty of robbery and assault.)

In 1988, Anthony M. Kennedy was sworn in as an associate justice of the U.S. Supreme Court.

(Hanssen later pleaded guilty to espionage and attempted espionage and was sentenced to life in prison without the possibility of parole.) Auto racing star Dale Earnhardt Sr. died in a crash at the Daytona 500; he was 49.

Ten years ago: The United States vetoed a U.N. resolution that would have condemned Israeli settlements as illegal and called for a halt in all settlement building; the 14 other Security Council members voted in favor of the measure.

Five years ago: In what was seen as a criticism of Republican presidential candidate Donald Trump, Pope Francis said that a person who advocated building walls was “not Christian”; Trump quickly retorted it was “disgraceful” to question a person’s faith. (A Vatican spokesman said the next day that the pope’s comment was not intended as a “personal attack” on Trump.) Dallas-based Heritage Auctions said a rare copy of a comic book featuring the first appearance of Spider-Man had been sold to an anonymous collector for $454,100.

One year ago: Japanese health authorities confirmed 88 more cases of the coronavirus aboard the quarantined cruise ship Diamond Princess, bringing the number of cases on board to 542; U.S. officials said Americans who chose to remain on board could not return home for at least two weeks after coming ashore. Health officials in the Chinese city of Wuhan announced that a hospital director who’d mobilized the hospital’s resources to deal with the thousands of sick people arriving daily had died from the virus. The Boy Scouts of America filed for bankruptcy protection in the first step toward creating a huge compensation fund for men who were molested as youngsters decades ago by scoutmasters or other leaders; the organization urged victims to come forward.
