B
【答案解析】[解析]
In many businesses, computers have largely replaced paperwork, because they are fast and do not make mistakes. Many banks put advertisements in the newspaper showing that their business deals are "untouched by human hands" and therefore safe from human temptation. Obviously, computers have no reason to steal money. But the growing number of computer crimes shows they can be used to steal. Computer criminals don't use guns. (29) And even if they are caught, it is hard to punish them because there are no witnesses and often no evidences. A computer cannot remember who used it; it simply does what it is told. One clerk at a New York City bank used a computer to steal more than one and a half million dollars in just four years. No one noticed this because he moved money from one account to another. Each time a customer he had robbed questioned the balance in his account, the clerk claimed a computer error, then replaced the missing money from someone else's account. (30) This clerk was caught only because he was gambling. When the police broke up an illegal gambling operation, his name was put in the records. Most computer criminals have been minor employees. But police wonder if this is true. As one official say, (31) "I have a feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know how a computer works."
