question:  How does the CPA prevent crime?
context: If I get drunk, I can join the AAA and get free room and board for a month while they give me a treatment." If your CPA ID says you're a DCT, you're SOL and they tell you there's no openings. A civilization weary of murder, robbery, kidnapping, counterfeiting, blackmail, rape, arson, and drunkenness had originated the CPA—Crime Prevention Association. There were no longer any prisons—CPA officials had declared loudly and emphatically that their job was to prevent crime, not punish it. And prevent it they did, with thousands of ingenious crime-prevention devices and methods. They had made crime almost impossible, and during the previous year, only a few hundred men in the whole country had been convicted of criminal acts. 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. An expensive operation, but since there were few criminals—only ten in New York during the past year—any city could afford the CPA hospitals. The CPA system was, actually, cheaper than previous methods because it did away with the damage caused by countless crimes; did away with prisons and their guards, large police forces, squad cars and weapons. And therefore, an EX (a convicted criminal who received the treatment was commonly called an Ex because he was in the strictest sense of the word an Ex-criminal) ... A crime because it theoretically inflicted psychological injury upon the intended victim—and because millions of women voters had voted it a crime. On the other hand, attempted murder, robbery, kidnapping, etc., were not crimes. They weren't crimes because the DCT didn't complete the act, and if he didn't complete the act, that meant simply that the CPA had once again functioned properly. The WSDA—Women's Self-Defense Association—a branch of the CPA.
