Early on, it looked ominous when an Air Force base on the southern edge of Tucson in the U.S. state of Arizona was locked down Friday morning amid unconfirmed reports of gunfire. In the end, no shots were fired, and no weapons and gunman were found.

Pakistan's prime minister canceled his attendance at next week's U.N. General Assembly session in New York, saying Friday he needed to coordinate flood relief efforts at home.

Monsoon rains have flooded large parts of the southern Sindh province over the last six weeks, leaving more than 200,000 people homeless. Pakistan's leaders came under criticism last year for failing to deal with floods that affected more than a quarter of the country's territory.

The Eisenhower era was a repressive time in America. Women could legally be harassed by police just for wearing pants, and homosexuality was considered a shameful crime as well as a mental illness, for which the police could toss a man or woman into a psychiatric hospital.

Illustrating this lack of civil liberties with smooth and entertaining song is "Play It Cool", a noirish jazz musical about a secret gay nightclub off Sunset Boulevard in 1953 Los Angeles, a town where the police were notoriously hostile toward gay people.
