Author Ray Bradbury got a  mixed review..from the FBI.

Recently declassified U-S documents show  the bureau investigated the “Fahrenheit 451” author in the 1950s and 1960s for suspected Communist sympathies.

An informant warned agents that Bradbury wrote stories that were “definitely slanted” against capitalism and added that science fiction itself could so terrify readers that they would succumb to “incompetence bordering on hysteria” and would be helpless during a Third World War.

The FBI  noted Bradbury’s opposition to anti-Communists and his support for civil rights but  it concluded that he had  never been in the Communist Party and interviewing him was unnecessary because he did not have “informant potential.”

Ray Bradbury died this June at age 91
