许多历史学家在谈到文字狱的时候，总拿出朱元璋时期的文字狱来为清朝辩护，以证明文字狱并非清朝首创，但是可悲的是，明朝有历史记录的文字狱，仅仅只集中在朱元璋时期，起因仅仅是因为朱元璋怀疑作诗者对他有嘲讽，而这样的案例并不见于明朝正史记录，只是乡间的传说比较多而已。退一步说，明朝的文字狱纵然确有其事，其性质也与清朝有本质的区别，清朝的文字狱本质上是一种民族的压迫和文化的破坏，明朝没有焚书，更没有如清朝办理“明史案”一样，去进行大规模的屠杀行动。

On May 29, 1973, Thomas Bradley, a black man, was elected mayor of Los Angeles. Los Angeles is the third largest city in the United States, with a population of three million. About sixteen percent of the city’s population are black.

News of this election appeared on the front pages of newspapers everywhere in the United States. Here is how one major newspaper reported the event.

LOS ANGELES ELECTS BRADLEY MAYOR UNSEATING YORTYBLACK WINS 56 OF VOTES

Bradley called his victory over Yorty "the fulfillment of a dream". During his childhood and youth, people had kept telling him, "You can’t do this, you can’t go there, because you are a Negro. " Nevertheless he had won a decisive victory over a man who had been won 43.7 percent.

Los Angeles voters have had many opportunities to judge. Thomas Bradley had to form an opinion of him. The son of a poor farmer Texas, he joined the Los Angeles police force in 1940. During his twenty-one years on the police force he earned a law degree by attending school at night. He was elected to the city council ten years ago.

At the time of the Los Angeles election, three other American cities already had black mayors, but none of those cities had as large a population as Los Angeles. Besides, the percentage of blacks in those other cities was much larger. Cleveland, Ohio, had thirty-six percent black when Carl Stokes was elected mayor of Cleveland in 1967. In the same year Richard Hatcher was elected mayor of Cary. In Newark, New Jersey, sixty percent of the population were black when Kenneth Gibson was elected in 1970. Thus election of a black mayor in those cities was not very surprising.

In Los Angeles thousands of white citizens voted for Thomas Bradley because they believed he would be a better mayor than the white candidate. Bradley had spent forty-eight of his fifty- five years in Los Angeles. Four years ago Bradley lost mayoral election to Yorty. This time Bradley won.
