By 1970, the city gained notoriety for high rates of crime and other social disorders. A popular song by Cashman & West in the autumn of 1972, “American City Suite”, chronicled, in allegorical fashion, the decline in the city’s quality of life. The city’s subway system was regarded as unsafe due to crime and suffered frequent mechanical breakdowns. Prostitutes and pimps frequented Times Square, while Central Park became feared as the site of muggings and rapes. Homeless persons and drug dealers occupied boarded-up and abandoned buildings. The New York City Police Department was subject to investigation for widespread corruption, most famously in the 1971 testimony of whistle-blowing police officer Frank Serpico.
