問題詳情：

In many businesses，computers have largely replaced paperwork, because they are fast, flexible and do not make mistakes. As the banker said, “Unlike humans, computers never have a bad day.”And they are honest. Many banks advertise that their trade is “untouched by human hands” and therefore safe from human temptation(誘惑). Obviously, computers have no reason to steal money. But they have no conscience and the growing number of computer crimes shows they can be used to steal.

    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, but simply does what it is told. The head teller at a New York City Bank used a computer to steal more than one and a half billion. No one noticed the theft because he moved the money from one account to another. Each time a customer he had robbed questioned the balance in his account, the teller claimed a computer error and then replaced the missing money from someone else's account. This man was caught only because he was a gambler. When the police broke up an illegal gambling operation, his name was in the records.

    Some employees use the computer's power to get revenge on their bosses they consider unfair. Recently, a large insurance company fired its computer-tape librarian for reasons that involved her personal rather than professional life. She was given thirty days notice. In those thirty days, she rubbed out all the company's computerized records.

Most computer criminals have been common workers. Now the police wonder if this is “the tip of the iceberg”. As one official says, “I have the 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. ”
