 What is the relationship between Hendricks and Joe?
There were no longer any prisons—CPA officials had declared loudly and emphatically that their job was to prevent crime, not punish it. Instead, he was sent to a hospital where all criminal tendencies were removed from his mind by psychologists, shock treatments, encephalographic devices, a form of prefrontal lobotomy and a dozen other methods. Anyone who knew Hendricks well liked him, for he was a friendly, likable person. The President of the United States was a capable man, but also a very handsome one, and the fact that a man who looked something like a bulldog had been elected as New York's police commissioner was a credit to Hendricks and millions of women voters. Hendricks rose from behind the desk, walked leisurely to where Joe was slouched in a chair.
