Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there are no witnesses and often no evidence. 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. 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.
Some employees use the computer's power to get revenge on employers they consider unfair. Recently, a large insurance company (保险公司) fired its computer-tape librarian for reasons that involved her personal rather than her professional life. She was given thirty days' notice. In those thirty days, she wiped out all the company's programmed records in the computer.
Most computer criminals (犯罪) have been minor (低级的) employees. But police wonder if it is true. As one official says, “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.”

In many businesses, computers have largely replaced paper work, because they are fast, and do not make mistakes. As one bank manager said, “Unlike humans, computers never have a bad day.” And, they are honest. Many banks put advertisements in the newspaper showing that their business deals are “untouched by human hands” and therefore safe from human temptation (诱惑). Obviously, computers have no reason to steal money. But they also have no conscience (良心), and the growing number of computer crimes shows they can be used to steal.
