The investigative reporter Seymour Hersh, in his memoir “Reporter,” describes a moment when as a young reporter he overheard a Chicago cop admit to murdering an African-American man. The murdered man had been falsely described by police as a robbery suspect who had been shot while trying to avoid arrest. Hersh frantically called his editor to ask what to do.
“The editor urged me to do nothing,” he writes. “It would be my word versus that of all the cops involved, and all would accuse me of lying. The message was clear: I did not have a story. But of course I did.” He describes himself as “full of despair at my weakness and the weakness of a profession that dealt so easily with compromise and self-censorship.”
